Auto spare parts-Wheel Hub Bearing

The key role of hub bearings is to bear the load and provide accurate guidance for the operation of the hub. 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 basically completed on the automobile production line. This structure makes it difficult to install and configure in automobile factories, high cost and poor reliability. In addition, when the car is maintained at the maintenance point, the bearing should be cleaned, refueled and adjusted. The hub unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings, which has the advantages of good assembly performance, eliminating clearance adjustment, light weight, compact structure, large bearing capacity, sealing bearings pre-filled with grease, eliminating external hub sealing, maintenance free, etc. It has been widely used in cars, and there is a trend of gradually expanding its application in trucks.

Traditional car wheel with bearing is composed of two sets of tapered roller bearings or ball bearings back to back or face to face, the installation of the bearing, oil seal and clearance adjustment is carried out on the auto production line.This structure makes it in the car factory assembly difficulty, high cost and poor reliability, and when the car in pits maintenance, also need to clean, oil bearing and adjustment.  The key role of hub bearings is to bear the load and provide accurate guidance for the operation of the hub.

Features of Auto spare parts-Wheel Hub Bearing:

1. Bearing surrounding full of water, dust;

2. Bearing often contact mud;   

3. Bearings will be used in high temperature and cold regions; 

4. Automobile hub bearings belong to double row angular contact ball bearings, which have the characteristics of double row angular contact ball bearings. Generally, double-half inner ring structure is used, and the base is large, which can be assembled and ensure axial clearance.

Application:

1.Carry out internal optimization design of bearings according to the worst working conditions of the models used;               

2. Inner ring, outer ring, steel ball are high purity special quality bearing steel processing;                                   

3. The cage is made of engineering plastics in accordance with YB/T6638, and its technical conditions are prescribed by JB/T7048; Or negotiate with the user to use other materials;                

4. The best composite sealing structure is generally adopted, and the sealing ring material is made of high-quality nitrile butadiene rubber and SPCC skeleton, and other types of rubber can be used according to special needs;   

5. Bearings are added with special grease customized for special working conditions of wheel bearings to meet the requirements of maintenance-free.
