Car wheel bearings are used in pairs over a maximum single row tapered roller or ball bearings. As technology advances, the car has been widely used car wheel unit. Cubo scope of use and the growing use of, has now developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has an outer raceway for the bearing retainer flange, can simply be FAG bearings sleeve onto the shaft with a nut. Makes the car maintenance becomes easy. Third generation wheel hub bearing unit is the use of the bearing unit and the anti-lock brake system compatible. Wheel hub unit designed to have a inner flange and outer flange, the flange is bolted to the drive shaft, the outer flange of the whole bearing mounted together.
Worn or damaged wheel bearing or hub unit will make your vehicles in the road occurred anachronistic and costly failure, and even damage to your safety. The use of the wheel bearings and installation Please note the following:
1, in order to ensure maximum safety and can be *, we recommend that you no matter how long the age of the vehicle should always check the wheel bearings - Note FAG bearings for wear early warning signals: includes any grinding noise when turning or hanging wheel assembly In turn, the deceleration is not normal.
Rear wheel drive vehicle is recommended to 38,000 km vehicle is to deal with the front wheel hub bearing lubrication. When replacing the brake system, check the bearing and replace the oil seal.
2, If you hear a wheel bearing parts of the emitted noise, first of all, it is important to find the noise occurs. There are many moving parts may produce noise, it may be a number of non-rotating member rotating member and the contact has occurred. If the confirmation is the noise FAG Bearings, bearing may be damaged and need replacing.
3, because the front wheel hub bearing failure on both sides led to similar working conditions, so even if only a bad bearing, also suggested replace in pairs.
4, wheel bearings are more sensitive, in any case need to adopt the right approach and the right tools. In the process of storage and installation, FAG bearing parts can not be damaged. Requires a large number of bearings pressed into the pressure, so they need special tools. Be sure to refer to vehicle manufacturers instructions.
5, the installation of bearings should be clean and tidy environment, small particles from entering the bearing will shorten bearing life. Replacement of bearings clean environment is very important. Not with a hammer percussion bearings, bearing note does not fall to the ground (or similar misconduct). Before installation shaft and housing should also check the situation, even with slight wear and tear can lead to poor, causing early failure of bearings.
6, the hub bearing unit, do not attempt to disassemble or adjust the wheel hub unit bearing seal, otherwise it would lead to water damage seals or dust from entering. Even ring and the inner ring raceways are damaged, causing permanent bearing failure.
7, is equipped with ABS unit bearing seal ring has a magnetic thrust, thrust ring can not be such a collision, impact or collision with other magnetic fields. Before installation remove from the box, so that they stay away from magnetic fields, such as the use of electric motors or electric tools. These bearings are mounted, through the observation of the dashboard road test needle ABS warning to change the operation of the bearing.
8, equipped with ABS magnetic thrust ring wheel bearings, thrust ring mounted in order to determine which side, you can use a light little thing * near the edge of the bearing, FAG bearings will be attracted by the magnetic force generated it. Installation will take the side of the magnetic thrust ring pointing inside, is on the ABS sensor. Note: Incorrect installation may cause failure of the brake system function.
9, many of the bearings are sealed, these bearings are not needed throughout the life of the grease in. Other non-sealed bearings such as double row tapered roller bearings in the installation must be added grease. The different sizes of the bearing cavity, it is difficult to determine how much additional fat, the most important thing is to ensure that the bearing with grease, if too much fat, when the bearing rotates, the excess oil will bleed. General Experience: At installation time, the total amount of oil to account for 50% of the bearing clearance.
10, due to mounting nut bearing FAG bearing types and the different torques vary greatly in size. Note reference to the relevant instructions.
