wheel bearing

The main function of deck crane bearing is to provide accurate guidance for the wheel hub bearing and rotating, it not only bear the axial load but also bear radial load,which is a very important component .

  The wheel of the car with the traditional thin section bearing is composed of two sets of tapered roller bearing and ball bearing assembly, bearing installation, greased, sealed and clearance adjustment is carried out in the automobile production line. This structure makes it difficult in assembly, automobile production plants of high cost, poor reliability, and vehicle repair points in the maintenance, also need cleaning, oiling and adjustment of the bearing.

  wheel bearing unit is developed in the standard angular contact ball bearings and tapered roller bearings on the up, it will be two sets of bearings are made into a whole, has good assembly performance, can omit clearance adjustment, light weight, compact structure, large load capacity, to advance into the seal bearing grease, ellipsis and external hub seal free from repair and other advantages, has been widely used in cars, in a truck is also gradually expand the application trend.
