Classification Of Automotive Bearings

In life, the number of cars is increasing, and the demand for wheel bearings on automobiles is increasing. Correct installation of automobile wheel bearings can increase the driving safety factor of automobiles. Excessive wear and bearing damage, if not replaced in time, will bring certain hidden dangers to driving safety.

Single row tapered roller bearing

◆ The inner and outer rings can be installed separately;

◆ The rear wheel that can be used for drum brakes (such as Santana rear wheel);

◆ It has higher carrying capacity and relatively low speed;

◆ Small installation space and easy to install;


Generation of wheel bearings

◆ Fixed, pre-set bearing clearance;

◆ Lifetime lubrication, maintenance free;

◆ permanent seal;

◆ The sealing ring is divided into: rubber oil ring and combined oil seal;

◆ Compact structure;

Second generation hub unit

The second generation of wheel bearings combines the advantages of the first generation economy and integrates a hub flange for mounting the brake disc and rim. The second generation of hub bearings is a compact bearing unit with a fixed Pre-set bearing clearance, lifetime lubrication (maintenance free), sealed.


◆ Integrated a hub flange;

◆ A certain pre-set bearing clearance, integrated with the hub flange;

◆ Rolling and flanging technology, fully pre-tightened;

◆ The snap ring provides the axial tension of the bearing outer ring and makes the bearing firmly fixed;

◆ Multiple sensors can be integrated in the seal ring to support ABS (anti-lock brake system), ASR (drive anti-skid device), ESP (electronic stability system);

Three generation hub unit

The third generation of wheel bearing is a highly integrated wheel bearing unit with a mounting flange for mounting the brake disc and a flange for the steering knuckle to ensure maximum running accuracy. The integrated speed decoder provides the signals needed for ABS/ESP suspension control. The tightening force of the hub bearing acts and is regulated by the annular boss.


◆ Compact structure, high bearing capacity, lifetime lubrication and sealing;

◆ Reduced shaking and improved driving comfort;

◆ High precision brake disc and wheel guide;

◆ Double flange design, installation does not need to adjust bearing clearance, installation is more convenient;

◆ Life is more reliable and has a longer service life;
