Structure and types of bearings
The product consists of the following parts:
- pairs of rings (external and internal), between which the rolling elements are located;
- rotating elements (balls, conical or cylindrical rollers);
- a separator (made of steel, non-ferrous metal or plastic) separating or holding the rolling elements at a given distance;
- protective washers that hold the lubricant inside the structure (they are not always used, they are present in ball bearings for a number of automobile hubs);
- rings holding the product in the unit body (found on units intended for installing shafts in the gearbox of VAZ or foreign cars).
Bearings are divided into 2 types:
- sliding (for example, used in crankshaft bearings of car engines);
- rolling (divided into conical, ball or needle).
Wheel bearing selection criteria
To select a wheel bearing, focus on the following criteria:
Bearing type
Depending on the design, there are single-row ball and roller, HUB type. When replacing, you must choose a part with a similar design that is installed in the car at the factory.
Material of manufacture
Wheel bearings are made from a variety of materials. Many manufacturers use steel. This is a practical and time-tested material with an optimal price-performance ratio.
There are ceramic bearings for sports cars. These are high-strength, elastic parts that are resistant to adverse environmental factors and weigh less than steel parts. Russian manufacturers of wheel bearings do not use this material in the manufacture of spare parts.
Design
Wheel bearings come in open or closed types. The first is considered cheaper and structurally simpler, but requires lubrication. The lubricant is filled to 70-90%, otherwise the lubricant will squeeze out during installation.
The closed type spare part is considered more reliable. The core of the part is reliably protected from moisture, dust, and dirt. This bearing does not need to be lubricated.
Equipment
To successfully install a wheel bearing, additional components are required: nuts, bolts, pins, seals, etc. The package must include all required fasteners without external damage (chips, scratches, cracks).
When dismantling a heavily worn or damaged bearing, old bolts stretch. Therefore, when installing spare parts, use new fasteners.
Vehicle operation period
One of the additional criteria for choosing a spare part is the period of operation of the machine. If the car will be used frequently and for a long time (another 3-4 years), then buy expensive spare parts from well-known manufacturers. The service life of such parts is about 100-120 thousand km.
If the car often sits idle in the garage or will be sold, then buy Chinese wheel bearings. These parts are of lower quality, but cheaper. Such spare parts are not much inferior in performance characteristics to foreign analogues, but they are inferior in terms of service life. Chinese bearings are enough for 20-30 thousand km.
List of suppliers
- SNR is the largest French supplier in Europe and rightfully ranks first in product quality;
- 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.
Purpose
The products are designed for the correct positioning of rotating shafts (for example, in gearboxes or front wheel drives).
Due to the introduction of balls or rollers, the units are able to absorb shock loads; when installing protective rings, operation in water or liquid mud is allowed.
The products are capable of operating at temperatures up to +150…200°C without reducing service life or risk of jamming (for example, in wheel hub units of passenger or commercial vehicles).
The type or design of bearings depends on which hub is used on the machine. For example, in Zhiguli cars with rear drive axles, conical joints are used with tension adjustment using a nut (which is then fixed in a tightened position). On vehicles with front-wheel drive, 2-row ball units are used that do not require periodic adjustments during operation of the machine.
Preparing for work
This process is best carried out in the light if we are talking about the street. A bearing is a miniature component. It will be ideal if you drive Priora into the inspection hole. We will disassemble the front hub part, since this is more difficult than carrying out the same operation with the rear hub, especially without removing the strut. And now to the tools:
- Spanners for 17, 19.
- A bearing puller is the main tool, so without it you will have to dismantle the strut and perform a wheel alignment.
- The head is 30, it is desirable that it be equipped with a reliable wrench.
- The frame is usually a homemade tool, which is a cut of a pipe of a certain size. With its help we will knock out the hub.
- WD-40 lubricant.
How to distinguish an original from a fake
Before buying bearings, you need to find out the characteristics of the original product. For example, special coded markings can be applied to rings, and a holographic label can be applied to cardboard packaging. Some manufacturers include mounting elements (for example, fastening nuts or seals) in the kit, allowing assembly of the unit without purchasing additional spare parts.
Information about the labeling or composition of the kit is available on the websites or in the official catalogs of manufacturers.
In mid-2022, the JTECT concern, which owns the Japanese manufacturer Koyo, together with the WBA (World Bearing Association, an international association of bearing manufacturers), introduced a program to verify the authenticity of products using a QR code printed on the packaging. After comparing the information with the database, a green or red indicator is displayed on the smartphone screen, indicating the original origin or counterfeit. As of mid-2022, the labeling program is in the development stage, and mass application of labels on packaging has not begun.
Signs of a low-quality spare part
The main signs of counterfeit products:
- packaging made of low quality material;
- grammatical or punctuation errors in the description (on the box or insert);
- absence of protective holographic stickers (subject to installation of elements on original products);
- scratches or other mechanical damage to the rings, separator or protective washers;
- lack of information or erroneous information about the manufacturer or catalog number;
- noise when the rings rotate or a palpable beating of parts.
Symptoms of failure
We replace the bearing when the following symptoms appear:
- Noise and knocking noise in the front hub.
- Severe play on the bearing.
- Leakage of grease from under the bearing seal.
- Mechanical damage to the unit.

Best rear wheel bearings
Finding good wheel bearings for the rear axle is a little easier, since they take on less load. Because of this, there were many contenders for the leading position. But only three products from Bavarian manufacturers passed the selection based on price/quality ratio.
NK 763924
Bavarian manufacturer of spare parts for cars in the budget segment. This brand produces: ball joints, levers, silent blocks, stabilizers and hub rollers. The last element is divided into 2,000 models that are suitable for all brands of passenger vehicles.
Replacement
The work must be carried out using the necessary tools. There are two options for replacing the wheel bearing - with subsequent wheel geometry and without its need. The replacement is similar for all VAZ cars (front-wheel drive).
Tool you will need:
Replacement with subsequent wheel geometry
According to the laws of physics from the school curriculum, cold bodies contract, and hot bodies expand. Therefore, a cold bearing will have a smaller diameter than a hot one, making installation easier.
You can use an old bearing as a mandrel.
Replacement without wheel geometry
In order to carry out a replacement without the need for wheel geometry, it is necessary to completely dismantle the steering knuckle assembly with the strut.
The next step is to remove the bearing from the knuckle and install a new one.
An old unnecessary bearing can be used as a mandrel for installing a new one.
The wheel bearing replacement process is complete.
The best front wheel bearings
The budget price segment includes about 10 models of car front wheel bearings from French, Russian, Japanese, Swedish and Chinese manufacturers. Competing products differ from each other in size, appearance, rated load and established warranty period.

A large Japanese manufacturer that began producing roller and ball bearings almost 100 years ago, which today offers more than 100 thousand types. The company's production facilities and research centers are located in Asia, America and Europe. Excellent characteristics are confirmed not only by the presence of international certificates of conformity, but also by the popularity of this brand among consumers in different countries of the world.
Separately, we should highlight the production of components for cars and automotive bearings for various purposes. The company's specialists monitor all stages of production and regularly test products for resistance to aggressive environmental conditions and endurance under the most extreme loads. For owners of domestic car brands, KOYO products are also of interest. Wheel bearings from this company can be installed on almost all VAZ, Niva and other brands. At the same time, the service life is several times longer than domestic analogues, so the difference in cost does not affect demand at all.
What to look for when choosing bearings for a hub
When choosing wheel bearings, you should pay attention to the following nuances:
- period of operation of the machine. If you continue to use the car, you should take high-quality foreign models. To sell a vehicle, inexpensive Chinese analogues will be sufficient;
- choose those manufacturers who supply their goods to the assembly line (for car assembly). In this case, the quality of spare parts is confirmed by many tests of the automaker;
- You can’t rely solely on size. Externally identical parts can differ greatly inside (for example, balls with different diameters). An unsuitable element will fail faster and can also lead to unit failure;
- exposed bearings must be lubricated before installation. Choose high-quality wheel bearing lubricant, the service life of which corresponds to the period of operation of the bearing;
- It is better to entrust the installation to professionals (especially if you do not have the appropriate experience and equipment). Otherwise, you can only damage the part.
If you don’t know which bearings are better, then you should take a closer look at more famous brands. In this case, you will receive reliable and durable parts that will serve you for a long period.
Popular packers
Also quite well-known brands that are often found in our markets. They do not produce spare parts themselves, but only package them.
- Ruville. A very large supplier, but at the same time, it cooperates with leading manufacturers and also packages counterfeits. As a result, it is difficult to talk about quality;
- Optimal. A Polish company that has previously collaborated with leading brands such as IRB, SKF and FAG. At the same time, now there are often fakes from China and CIS countries;
- H.K. Former FAG division, very high quality;
- Q.H. Packages Chinese original goods. The quality more or less matches the price;
- Corteco. The cheapest Chinese manufacturers, the quality is one of the lowest;
- SH. Mostly either low-quality bearings or fakes.
Such components are somewhat more expensive, since you also have to pay a markup for the packers. As a result, it is better to contact the manufacturer directly if this option is available.
Bearings for cars of the Russian automobile industry
The domestic auto industry, which produces passenger cars, still uses old types of bearings in production - single-row roller bearings. Only AvtoVAZ switched to two-row closed hub type HUB-1. HUB-1 means there are no flanges on the body for mounting to the hub. Therefore, owners of Russian car brands have a question about which wheel bearings are better. The most common vehicles on Russian roads today are VAZ 2110, GAZelle, and UAZ Hunter. Of course, you can purchase original parts, but they are often twice as expensive as similar ones from other factories. Let's look at the example of these particular brands of companies that produce the necessary parts.
Bearings for VAZ 2110
For the modern line of VAZ passenger cars (except Niva 4x4, Chevy Niva), three standard sizes of wheel bearings are produced:
- 256907 - for front-wheel drive VAZ 2108-2112;
- 256707 - on Granta, Kalina;
- 256706 - on the rear axle.
All these models belong to HUB-1, double-row, ball, closed, angular contact. Lada Granta and Kalina differ only in height.
Traditional suppliers of bearings for cars from Togliatti are 5 factories:
- CJSC "LADA Image" - manufactures and sells original Lada wheel bearings through secondary markets;
- Saratov plant - produces parts under the SPZ brand;
- Volzhsky Plant - uses the Volzhsky Standard brand;
- Vologda plant - sells products under the VBF brand;
- Samara plant SPZ-9.
The price-quality ratio of these factories is optimal. The cheapest products are those from the Samara plant (less than 200 rubles), other companies on average sell parts costing 230-275 rubles.
Bearings for UAZ
UAZ hubs use bearing 127509 - roller, conical, single-row, angular contact. There are additional parts marked: A - reinforced and AK - with minor design changes. The part can withstand large axial loads, so the car can be operated in difficult road conditions.
Parts of this type are produced by the Samara and Saratov plants, already mentioned above, as well as the Moscow GPZ-2 and Lutsk (LPZ) plants.
The most affordable products are from GPZ-2, the cost is 182 rubles.
Bearings for GAZelle
The front hubs of GAZelles are equipped with two tapered bearings, roller, angular contact, single-row. The outer one is marked 7305АШ, the inner one is marked 7307А. Both are designed to handle heavy loads.
Such bearings are manufactured at the Volzhsky and Saratov plants. The kit often consists of two bearings, fasteners, lubricant, stopper, and seals. The cost of such a kit from VPZ is 350 rubles.
In addition to Russian manufacturers, there are foreign companies that produce similar products, but prices are usually higher.
Before purchasing parts for hub repair, carefully study which suppliers offer the highest quality products, and check that the parts have the appropriate engraving. It’s better not to try to buy cheap, low-quality parts, because your safety depends on it, and such “savings” can lead to a major breakdown and a serious accident.
Stories from our readers
“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Tips for choosing
Never select bearings based on size alone. Inside 2 identical bearings there can be balls of different diameters, designed for small or large loads. An incorrectly selected spare part will quickly fail.
1. Buy spare parts at auto stores or service stations
This reduces the risk of error when choosing a part, especially if the car owner is poorly versed in the technical part of the car. Experts will tell you which wheel bearings are suitable for your car.
2. Avoid unlabeled products
High-quality wheel bearings have factory markings at the bottom or top of the part, consisting of numbers and letters. The marking contains information about the manufacturer, country and date of manufacture, size, etc.
3. Use specialized programs
Wheel bearing selection becomes easier when you use different applications. For example, the TecDoc program allows you to select a part from different manufacturers that is similar to the original spare part.
