High-speed bearing factory direct sales DAC38740236/33 Auto wheel hub bearings unit

The wheel hub bearing is one of the key components of the automobile. Its main function is to carry weight and provide precise guidance for the rotation of the wheel hub, which requires it to bear not only axial load but also radial load.Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all performed on the automobile production line. This structure makes it difficult, costly and unreliable to assemble in automobile production plants. Moreover, when the automobile is maintained at the repair point, the bearings need to be cleaned, oiled and adjusted.
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. It has good assembly performance, can omit clearance adjustment, is light in weight, has a compact structure, and has a large load capacity. Large, sealed bearings can be filled with grease in advance, omit external hub seals, and are maintenance-free. They have been widely used in cars, and there is also a trend of gradually expanding their application in trucks.
