Automobile Bearing

The main development of our automobile bearing is expanding the scope of general bearing application; improving the performance and lifespan of general and special bearing. They are more convenient for automobile installation, to make the bearing installation lightweight integration long life, high reliability and low cost in total.

This bearing also to be called hub bearing.The main function of hub bearing is to load and provide precise guidance for hub rotation. It bears both axial and radial loads, and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are carried out on the automobile production line. This structure makes it difficult to assemble in automobile factory, high cost and poor reliability, and the bearings need to be cleaned, oiled and adjusted when the automobile is maintained at the maintenance point. Hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It integrates two sets of bearings. It has the advantages of good assembly performance, eliminating clearance adjustment, light weight, compact structure, large load capacity, pre-loading grease for sealed bearings, eliminating external hub seal and avoiding maintenance. It has been widely used in cars. There is also a trend to gradually expand the application of trucks.

In the past, the hub bearings of cars used to be paired with single row tapered roller or ball bearings. With the development of technology, car hub unit has been widely used. Hub bearing unit has been used more and more widely, and now it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fix the bearing sleeve to the axle with a nut. Make car maintenance easier. The third generation hub bearing unit adopts the combination of bearing unit and ABS of anti-lock braking system. The hub unit is designed with inner flange and outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the whole bearing together. Weared or damaged hub bearings or hub units can cause inappropriate and costly failure of your vehicle on the road, and even harm your safety.
