Front wheel bearing size VAZ 2109 dimensions

The purpose of the bearing is to reduce the rolling resistance of the vehicle. Therefore, wear and tear is a normal process that occurs as a result of vehicle operation.

In modern passenger cars, two types of wheel bearings are used according to requirements:

1. Ball.
2. Roller (conical).

The versions of these products used vary depending on the application and load.

These bearings are designed and rated to withstand high loads and environmental levels. Severe radial (caused by potholes) and axial (caused by hitting curbs) impacts are their biggest enemies. Extreme cornering also reduces wheel bearing life due to the high axial lateral forces generated. In addition, the product is exposed to factors that shorten its service life, such as:

• Corrosive water;
• Dust and sand that penetrate the housing;
• Speed ​​inappropriate for rough roads.

The most common sign of wear is its noisy operation, as well as the noise of mechanical friction and vibration transmitted to the body and steering system.

Bearing 256907

The main area of ​​its implementation is the front wheel bearing of VAZ 2108, 2109, 2110, 2111, 2112 cars. It has the following design features - ball, angular contact, double-row, closed type (seals on both sides). The double row ball bearing has the ability to be locked on both sides. Bearing 256707 is installed in the front hub of the most modern VAZ models (Kalina, Granta).

Since most VAZ models have become widespread not only in our country, but also abroad, the need for front hub bearings is very high - they are created immediately at 4 factories in our country:

• OJSC (form of organization of a public company; joint stock company)
  “Saratov Bearing Plant” (labeled SPZ) - according to professionals, produces the best front wheel bearings in our country, and at the same time they are not very expensive. Purchase from official representatives in your region (only they have a guarantee of authenticity and, at the same time, small trade margins - the cost of a wheel bearing will be about 350 rubles).
• 23 GPZ (or VBF, Vologda) - among motorists it is considered the best plant, but the wheel bearings of the previous manufacturer are in no way inferior to them in durability, are less likely to be counterfeited and are slightly cheaper.
• SPZ-4 (Samara) - produces products for those who are used to saving. But if you need a high-quality front wheel bearing, it is best to focus on the manufacturers presented above.
• 20 GPZ (Kursk) - currently not performed, but some companies still sell them; you will not receive a guarantee of their long-term performance.

For off-road use, it makes sense to install hub roller bearings 537907, which have an increased load capacity, but a lower maximum rotation speed.

Russian bearings are manufactured in accordance with GOST 520-2002, imported from other countries in accordance with ISO 15:1998. According to the international designation system, the number of this bearing is 532066DA.

Technical characteristics and dimensions of the front hub bearing 256907:

Internal diameter (d): 34 mm;

External diameter (D): 64 mm;

Ball diameter: 9.525 mm;

Number of balls: 28 pcs.;

Dynamic load capacity: 31.5 kN;

(Load capacity of the roller bearing of the hub 537907 - 68.6 kN);

Static load capacity: 27.9 kN;

(for a roller wheel bearing this value is 99.8 kN);

Rated speed: 6000 rpm. (for a roller, this value is less)

Engineering Features

The spherical roller 2109 enhances the technical parameters of the roller bearing. The geometry of the inner surface of the outer ring makes it possible to compensate for misalignment. Roller bearings are used under conditions of uneven and significant radial stresses.

Failure to maintain alignment changes the motion of the rolling elements. The quality properties of roller bearings are reduced. The axes of the installation sites certainly require adjustment.

The marking of 2109 bearings is described by GOST 3189. The designation contains numbers and letters. The designation includes the main characteristics of the bearing.

The composition includes outer and small rings. Working media - short or long rollers. Rotating rollers are screwed into cages. Mechanism 2109 is the support of the rotating device.

Basic deviations of roller bearings are designated by the letters lb L. The letter L is used to mark the inner ring. The outer ring of a bearing with accuracy class 6 is designated l6 (el 6). The letter l is used for the outer ring.

The outer surface of the inner ring and the large one inside also have running tracks. During activity, rollers roll in the chutes. Operation involves rolling friction.

Auxiliary design features are present in products with short rollers (rolling bodies). They do not function well enough at high speeds. The design flaw is the inability to absorb axial load. The advantage is high load-bearing capacity.

VAZ 2108 front wheel bearing size

No matter what spare part a modern car needs to be perfectly matched to fit and technological dimensions. Much to our chagrin, the manufacturer does not constantly take into account the individuality of the use of materials in spare parts, which affects their service life, reliability, and, ultimately, safety of movement. The chassis of a car is subject to enormous overloads, so it is simply unacceptable not to pay attention to the correspondence of industrial sizes with the ones being replaced.

VAZ 2108 front wheel bearing size

If we take this issue more specifically, the chassis of cars of popular models and brands most often suffers from low-quality spare parts. First, let's look at this problem using the example of a VAZ 2108 front wheel bearing.

It would seem that there is nothing complicated - the hub has its usual dimensions, which the roller bearing must correspond to:

internal diameter - 34 mm; external diameter - 64 mm; Bearing width - 37 mm.

Only based on these characteristics can you select a bearing, of which Russian factories produce thousands. Manufacturers from China actively help with this, providing products that are not of the best quality and do not stand up to any criticism. Neither the steel grade, nor the number of balls, nor the dynamic characteristics of such bearings correspond to the standards. There are bearings completely unmarked, and there are especially careful owners who purchase them. Such bearings burn out within 1000 km and simply fall apart while driving.

Individual selection of wheel bearings for VAZ 2108

Naturally, we will not be able to check the dynamic load on the bearing races or on any of its balls. But it is necessary to understand, like Our Father, that:

• The VAZ 2108 wheel bearing is marked 25 69 07;
• according to the international marking system it is designated 53 20 66 DA;
• the bearing has a mass of 0.445 kg;
• ball diameter - 9.525 mm;
• number of balls - 28.

The difficulty in choosing bearings lies in the fact that they are not consumable parts, and they are not changed as often as piston rings or silent blocks. That’s why some manufacturers don’t even bother making human packaging. In addition, the bearing used in the front wheel hub of the VAZ 2108 is maintenance-free, which means:

• the bearing does not require lubrication;
• does not require preload;
• does not require adjustments during installation and operation;
• must have a very high resource.

Wheel bearing system for VAZ 2108

All VAZ cars are equipped with only 3 types of wheel bearings - wheel bearings for front-wheel drive VAZ cars, wheel hub bearings for rear wheels, and wheel bearings for Kalina and Granta cars, which differ in their smallest sizes.

All VAZ bearings are of the HUB-1 type, and this type is characterized by the system and the individuality of the installation. The bearing has a double-row system, is a type of angular contact ball bearings with closed working surfaces and does not have flanges for attachment to the hub.

Manufacturers and prices of VAZ wheel bearings

These bearings belong to the middle price sector, therefore the demand for them is very high. Because of this, you can often come across the fakes that we mentioned. However, the transition of the VAZ plant to bearings of this type, instead of roller bearings, the old standard, made it possible to choose bearings not only made in Russia, but also from almost all other foreign factories.

Important points

As can be seen from the article, replacing wheel bearings is a rather labor-intensive task, even taking into account the fact that the article provides the simplest method (an alternative replacement method allows you to do without removing the steering knuckles, but in this case the car owner will definitely need an inspection hole, which is far from available everyone has). In the method proposed above, a hole is not needed, and the main difficulty is not to disturb the camber of the car’s wheels. If the alignment still turns out to be damaged, there is only one way out: go to the nearest car service center and adjust the alignment again.

Front wheel bearing VAZ-2108: dimensions, description, photo

According to the car's maintenance card, it is necessary to replace the bearings of the front hubs of the VAZ-2108. Their dimensions are larger than similar ones installed on the VAZ 2101-2107 model. At the same time, there are individualities in carrying out the substitution. The “classic” uses tapered bearings; it is absolutely necessary to observe the permissible force when tightening the hub nut. Otherwise, the bearing will fall apart and you will have to buy a new one. Eights use cylindrical bearings; when tightening the hub nut, you need to apply as much force as you can - just don’t strip the threads.

Analogs and modifications

An excellent replacement for the Russian bearing 256706 will be its imported analogue BA2B633313C. It is important to take into account the country of production of the substitute and the brand. Low-quality Chinese parts are often sold under the same markings.

In some cases, it is worth paying attention to the roller analogue 537906. This product has exactly the same dimensional characteristics, but has a much greater load capacity, although at a significantly lower operating frequency.

Such a replacement is appropriate for older VAZ models that are operated in difficult conditions. This is especially true when driving in rural areas, where load capacity is much more important than speed characteristics.

Signs of a broken wheel bearing

As the vehicle is used, its components and assemblies wear out. In this case, those that suffer the most are those that are constantly loaded - these are rubbing parts. The weight of the motor and the friction force act on the bearing of the front hub of the VAZ-2108. That's why its dimensions are so impressive - to cope with overload. But when an element fails, the following symptoms appear (Symptom from Greek - case, coincidence, sign - one separate sign, frequent manifestation of a disease, pathological condition or disruption of any vital process)

:

1. At early steps there is a barely noticeable rumble.
2. Minor vibrations transmitted from the wheels to the body may be felt.
3. As the bearing wears, the noise and vibration intensify.

If you do not replace it in time, the bearing may jam. During operation, there will be excess heating of the hub - there is very little lubrication inside the bearing race, the iron elements rub against each other.

Causes of malfunctions

And now about why the VAZ-2108 front wheel bearing breaks. Its dimensions (with a mass of 445 grams) are as follows:

1. Width - 3.7 cm.
2. Internal diameter – 3.4 cm; external – 6.4.

The most common reasons why a bearing lasts a long time is water ingress or impact. The bearing temperature increases if you drive for a very long time on the highway at high speed. If after this you get into a puddle, especially if you drive for a long time in swampy areas, the bearing will end up in the water. At this time, almost all the lubricant is washed away. After a short time you will hear extraneous sounds. It is worth noting that front-wheel drive VAZ cars, starting with model 2108, use a bearing consisting of two rows. It does not need to be lubricated during operation, so the risk of water washing away all the lubricant is extremely small. Very often, the cause of premature failure of the wheel bearing is driving on uneven roads. For example, when you are moving at speed, notice a hole, and begin to press the brake pedal sharply, then you are causing enormous damage to your car. Oddly enough, getting into a hole at speed without pressing the brake is much safer. The fact is that inertial forces arise, weight begins to move from the rear axle to the front. And when a direct impact occurs, the front wheel bearing is subjected to many times greater forces. For this reason, the front wheel bearing of the VAZ-2108 will need to be replaced.

Repair tool

To replace the VAZ-2108 front wheel bearing, you will need a tool. All work must be carried out on a perfectly fixed frame. You will need the following tool:

1. Set of keys and sockets.
2. Mounting blade.
3. Bearing puller.
4. Gas-burner.
5. Jack, wheel chocks and secure supports.
6. A small piece of pipe with a diameter of 10 cm.
7. Hammer and chisel.
8. Pliers for removing retaining rings.

The methodology for carrying out work on the left and right wheels is similar. It is better to replace the bearings on both sides at once. It is necessary to install elements from the 1st and the same manufacturer, which are recommended by the factory.

Preparing for repairs

Now it's time to remove the old VAZ-2108 front wheel bearing. Its dimensions are indicated in the article below; when pressing out, you can use a clip from an old roller. Before starting work, do the following:

1. Unlock the front hub nut.
2. Using a 30mm wrench with a huge lever, remove the nut.
3. Place wheel chocks under the rear wheels.
4. Remove the wheel bolts.
5. Raise the side to be repaired with a jack.
6. Install supports under the frame.
7. Remove the wheel and place it under the car engine.

That's all, now you can start dismantling the front wheel bearing of the VAZ-2108. The sizes of the old and new ones must match. If the diameter is slightly larger or smaller, the bearing will not be able to work correctly.

Removing the front wheel hub

Now you need to remove the hub. To do this you will need:

1. Mark the position of the hub on the strut using a marker. Be sure to thoroughly clean the surface before doing this.
2. Use keys “17” and “19” to unscrew the nuts from the bolts securing the hub to the shock absorber strut.
3. Using a "17" key, you need to unscrew the lower bolts securing the ball joint to the hub. This is a common option when there is no need to replace the ball. But if it is necessary to change it, then you need to unscrew the nut from the ball pin using a “19” key and remove it using a puller.
4. Unscrew the hub nut completely.
5. Carefully knock the front wheel hub off the CV joint.

Bearing removal

To remove the bearing from the seat, you will need a puller. You can make it even without the help of others, there are no scarce components, the system is very common. The VAZ-2108 front wheel bearing puller is a long bolt with a large thread and a nut. And the most important thing is spacers and mandrels with a diameter similar to that of a wheel bearing. If there is no such puller, then all the work can be done with a hammer, but there still must be a mandrel.

First, remove the hub itself, in which the holes are made for attaching the wheels. Next you need to use pliers to remove the retaining rings. If you don’t have such a tool, you can use a flat-head screwdriver, pliers and an awl. After removing the rings, you can begin pressing out the bearing. If you do this with a hammer, then try to hit it literally and sharply, so the bearing will come out faster.

Bearing sizes

The article contains a photo of the VAZ-2108 front hub bearings, as well as a drawing of a puller indicating all dimensions. Therefore, if you doubt whether you got the right roller, check the dimensions of the hub. The part number is 256907.

The dimensions of the element are:

1. The outer diameter of the holder is 64 mm.
2. Internal diameter – 34 mm.
3. Weight – 445 g.
4. Balls with a diameter of 9.525 mm are installed inside.
5. The total number of balls is 28.
6. The unit is designed to operate at rotation speeds above 6000 rpm.

In any auto store, salespeople will be able to recommend a higher quality product for you.

Diameter and number of balls

The rolling elements of this bearing are placed through a special groove. Balls with a diameter of 9.525 mm are used as moving elements of the product. In the space between the clips they are placed in two rows, the total number per unit is 28 pcs.

The balls are held at specified positions using a separator. Its task is to position the rolling elements, but not to interfere with their free rotation.

There are ball bearings 256706 with a cage made of steel (without additional designation) and plastic materials: textolite (E, E1, E2) and polyamide (E9).

These features significantly affect the characteristics of a particular product, and therefore, before buying a replacement, you should learn more about the pros and cons of a particular separator.

Important! The use of composite materials for the manufacture of wheel bearing cages can significantly reduce their weight without compromising consumer characteristics. In addition, if such parts fail, they do not create solid debris that can aggravate the situation.

Manufacturers

Almost all motorists do not know which VAZ-2108 front wheel bearing to choose for their own car. At the moment you can meet several manufacturers on the market:

1. GPZ-23, Vologda, has the abbreviation VBF. The plant has earned the trust of motorists and is one of the best manufacturers of wheel bearings for Russian cars. Due to the relatively low price, these parts are virtually uncounterfeited.
2. SPZ, Saratov - as almost all experts believe, the bearings of this manufacturer are the most reliable, long-lasting and high-quality. And the most important thing is the very low cost of parts.
3. GPZ-20, Kursk is no longer engaged in the creation of wheel bearings, but you can find products in stores and warehouses.
4. Specialists do not speak very well about the Samara SPZ-3. The cost of the bearings is very low, and their quality does not shine, the service life is very short.

Some auto shops try not to get involved with little-known companies that create bad products. That’s why you can only find Saratov and Vologda bearings on the shelves.

List of suppliers

• SKF is the second-ranked supplier of bearing products, known in the markets for 100 years;

• NSK is also the second largest manufacturer of wheel bearings in the world from Japan;

• FAG is a manufacturer from Germany, absorbed by the INA concern, with high quality products;

• NTN is Japan's largest manufacturer;

• Kouo is the third largest manufacturer in Japan and is part of the Toyota concern;

• Timken is a manufacturer from the USA, the largest in the production of tapered bearings, the quality of which is exceptional.

These companies own many factories around the world, producing products of similar quality that meet the most stringent requirements.

If you need bearings for agricultural machinery, then it is better to pay attention to FKL, a Russian company located in Voronezh. Parts from this company have been supplied to all European countries for 50 years, are known for their high quality, and have no analogues in the world.

Installing the latest bearing

To simplify installation, you can use a little trick - warm up the hub a little and cool the bearing in the freezer. In the first case, the alloy will expand, in the 2nd case it will contract. Pressing will be much easier and faster. The main thing is not to overheat the hub, otherwise the seal on the bearing will melt and the lubricant will leak out. As a result, you will have to take the latest spare parts and make a new repair.

Lubricate the inner surface of the hub and install the retaining ring on one side. Carefully now you can begin to press in the wheel bearing of the VAZ-2108. If the dimensions are correct and there are no deviations in the geometry of the nodes, assembly will not take much time. When finished, install the 2nd retaining ring. Assemble the entire assembly and install it on the CV joint, tightening the bolts at the top and bottom. Replace the ball joint as necessary.

Tightening the hub nut is done with a wrench to “30” with a very enormous force after assembling the entire suspension and installing the car on the wheels. The entire assembly is done in reverse order, do not forget about the marks on the surface of the shock absorber strut. After all the work, make sure that there is no significant wear on the tires - otherwise, do a wheel alignment.

wwss75 › Blog › Front wheel spacers for maintenance-free bearing 2108

I rewrote it, corrected it, added it. part 1. HURRAY! It’s done, I’m holding the spacers in my hands. I have long wanted to create one for myself. It’s very difficult with a budget and purchasing via the web is no longer necessary. I couldn’t find it on sale in St. Petersburg, I heard a price tag of 2000 rubles. I contacted turners several times and was shocked by their price of about 6,000 rubles. for work. An old friend Andryukha came to the rescue. I found the time and, according to the drawing, turned it out of 45 steel, accurate to the hundredth. I didn’t take any funds :)) FRIEND! :)) I took the drawing from timur911, here is the link at www.drive2.ru/l/4438002/ In my drawing, 2 dimensions have been changed for the tightest fit of the spacer on the axle. Plus, the accuracy of production of two seating surfaces has a tolerance of 0.01-0.03 mm. (When making the inner surface, the turner makes dissatisfied faces and says that it is lazy and difficult to create) So, my version is a trial one! Everything in size will become clear after installation on the machine. I'll definitely write back. (18 months have passed, everything is EXCELLENT! Everything works! The drawing was corrected and correct 09/07/16.)

Part 2. Verification of dimensions after production during installation. The front brake disc from 2112 does not fit on the rear hub of 2108; it is necessary to grind the hub. I measured the front hub 2112 and got a fit for the disc of 58.5 mm. Since our hub has a larger fit for the brake drums, we grind the hub. The diameter is 58.5 mm on the contact side of the disc brake disc. Here, in this size, great precision is not needed; the brake disc is centered on the hub with bolts. The main thing is that he is dressed all the way to the hub. Bearing and spacer. The dimensions from the rear hub are taken as the base. 2108. This means that the installation of the bearing on our spacer must be similar. I watched a bunch of videos and articles on the web on how to remove and install the rear wheel bearing on a 2108. I also found the dimensions of these bearings and who makes them here. The diameter of the inner bearing race is exactly 30 mm. when measured with calipers 29.95mm. I identified both Russian and the latest bearings imported from other countries when I bought them from the store. The dealers also allowed me to measure the newest rear axle 2108, the size came out to be 30.01 mm. When installed, the bearing should not fit loosely on the axle, it does not have to be free-wheeling. In other words, the bearing fits tightly onto the axle (there should be no greater interference). As a base we take the control for installing the rear bearing. axles 2108.

What drives can be installed

When planning to replace old steel wheels with alloy wheels, you should choose either original products or products from well-known manufacturers who care about the quality and safety of their products.

Alloy wheels combine the following useful properties: they are lightweight, practical to use, endowed with sufficient strength and have an attractive appearance, which is aimed at transforming the entire appearance of the car.

The most common among alloy wheels are aluminum products. This is due to the fact that they are resistant to corrosion, meet strength requirements and, in comparison with other alloy wheels, remain relatively inexpensive.

Titanium alloy is the most expensive option. It also meets all the technical specifications, but at the same time has a more attractive appearance. In third place is the option using a magnesium alloy.

The latest models from AvtoVAZ use wheels with a 4x100 mounting pattern. When installing them on a 4x98 hub, you should use studs with an eccentric to compensate for the difference of 2 mm. To install disks with other mounting patterns, you will have to use the appropriate adapters (spacers).

You must understand that installing wheels larger than 15 inches is impossible without interfering with the car’s design.
