Auto bearings VKBA7497 43560-26010 54KWH02A-Y2CA 54KWH02 Front Wheel Hub Bearing BSSD

Car wheel hub bearing‌ is a type of car bearing. Its main function is to bear load and provide precise guidance for the rotation of the wheel hub. It can bear both axial load and radial load. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. This structure is difficult to assemble on the automobile production line, has high costs, and has poor reliability. The wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. The two sets of bearings are integrated into one, which has good assembly performance, can omit clearance adjustment, is light in weight, has a compact structure, and has a large load capacity. Large, sealed bearings can be filled with grease in advance, eliminating the need for external hub seals and being maintenance-free.

What are the commonly used bearings in cars Source: 

1. Ball bearings: used to support the axle, bear the weight of the vehicle and transmit power.    

2. Needle roller bearings: Mainly used for supporting components such as engines and transmissions.    

3. Sliding bearings: Mainly used in low-speed and heavy-load applications such as engine crankshafts and transmission input shafts.    

4. Tapered roller bearings: commonly used in automobile rear axle drive bearings.    

5. Cylindrical roller bearings: mostly used in automobile steering knuckles, wheel hubs and other components.    

6. Thrust ball bearings: usually used in automobile transmission shafts, universal joints and other components.    

7. Angular contact ball bearings: mostly used in automobile steering gears, brakes and other components.
