Bearings are an important part of automobiles, and bearings are the foundation to support automobiles. In the harshest environment, customers can also rely on the unique performance of sliding bearings, including: low friction, high wear resistance and high reliability. Bearing applications in automobiles include: wipers, shock absorbers, seats, gearboxes, braking, steering, folding convertible roofs, interior trim, pillars, control rods, pedals and other applications.

Steering system: steering support base, steering column, steering oil pump transmission system: rear output shaft, main shaft, reverse shaft, clutch, pump, solenoid valve, planetary gear set, shift fork seat: seat adjuster, height Adjusting mechanism and seat frame Axle: drive train, king pin brake system hinge: door hinge, trunk, hood hinge, automatic door closing device Engine management: water and oil pump, tensioner, pulley damper suspension and Shock absorber. Because most of the wheel bearings used in small passenger cars currently use sealed double-row angular contact bearings, this type of bearing is filled with grease to ensure the life-long lubrication requirements of the bearing, and the grease is sealed inside the bearing by an oil seal.

If this kind of automobile wheel bearing is damaged during driving, replace the assembly directly, and basically do not need to do any maintenance in the middle, so it can be said that this kind of wheel bearing is maintenance-free.

Automobile wheel bearings have now developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange for fixing the bearing on the outer raceway, and the bearing can be simply sleeved on the axle and fixed with a nut. Makes the maintenance of the car easier. The third-generation wheel hub bearing unit uses the bearing unit to cooperate with the anti-lock brake system ABS.

Many automobile wheel hub bearings are sealed, and this type of bearing does not need to be greased throughout its life. Other non-sealed bearings, such as double-row tapered roller bearings, must be lubricated with grease during installation. Due to the different sizes of the inner cavity of the bearing, it is difficult to determine how much grease to add. The most important thing is to ensure that there is grease in the bearing. If there is too much grease, the excess grease will leak out when the bearing rotates.
