Wheel Hub Bearing
The wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings into one and has the advantages of good assembly performance, no clearance adjustment, light weight, compact structure, large load capacity, grease can be pre-loaded for sealed bearings, no external wheel hub seals and no maintenance. It has been widely used in cars and there is a trend of gradually expanding its application in trucks.

Product Type
1.First generation wheel hub bearing: It is composed of double-row angular contact bearings, with a relatively simple structure, but it has a certain degree of maintenance convenience
2.Second generation wheel hub bearing: There is a flange on the outer raceway for fixing the bearing, which can be simply put on the axle and fixed with a nut, making the maintenance of the car easier
3.Third generation wheel hub bearing unit: A highly integrated bearing unit with a flange for mounting the brake disc and a flange for mounting the steering knuckle to ensure high-precision operation. The third generation wheel hub bearing unit also integrates a speed decoder to provide the signals required for ABS/ESP suspension control, improving driving comfort and reliability
Wheel Hub Bearing Advantage
1. Strong load-bearing capacity: wheel hub bearings can withstand various forces and torques during vehicle driving, ensuring driving stability and safety
2. Good fatigue resistance: wheel hub bearings can still maintain strength and stability under repeated loads, extending service life
3. Low friction coefficient: The friction coefficient of wheel hub bearings is low, reducing friction resistance during driving, improving fuel economy and driving comfort
4. Strong corrosion resistance: wheel hub bearings have good corrosion resistance and can resist the erosion of chemical substances to ensure driving safety
5. Easy installation and maintenance: The wheel hub bearing unit integrates two sets of bearings, omitting clearance adjustment, light weight, compact structure, and can be pre-loaded with grease, omitting external wheel hub seals and maintenance-free
