Quality Inspection for Car Hub Bearing - Automotive Wheel Hub Shaft Bearing 52711-02500 – JITO

*Specifications

The nearly port: Tianjin or Qingdao

1) Wheel Hub Bearing Unit Kit Assembly Introduction:

The main function of wheel hub bearing is to bear load and provides accurate guidance for the hub rotation. It is a very important part which can bear both the radial load and axial load. The traditional bearing for car wheel hub is composed by two set of conical roller bearing. The installation, greasing, sealing and adjustment of play are all done in the car production line.

2) About Wheel Hub Bearing Unit considerations:

For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the seal of the hub unit, otherwise the seal will be damaged and water or dust will enter. Even the raceways of the seal ring and the inner ring are damaged, resulting in permanent failure of the bearing.

3) Wheel Hub Bearing Precautions:

The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings and has good assembly performance, can eliminate clearance adjustment, light weight, compact structure and load capacity. Large, sealed bearings can be pre-loaded with grease, omitting external hub seals and maintenance-free. They have been widely used in cars, and there is a tendency to gradually expand applications in trucks.
