Product Description
The main structural form of the hub bearing is double-row angular contact balls or double-row tapered rollers. Its main function is to bear the load and provide precise guidance for the rotation of the hub. It is a very important part that bears both torsion and torsion.
Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance of the bearings are all adjusted on the automobile production line. The structure makes it difficult to assemble in the automobile production plant, the cost is high, and the reliability is poor. Moreover, when the automobile is maintained at the maintenance point, the bearing needs to be cleaned, oiled and adjusted.
The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. The two sets of bearings are made into components, which have good structural performance, can save clearance adjustment, light weight, compact structure, and large structural volume. , It is a sealed bearing, which can be pre-loaded with grease, saves the external hub seal and is free from maintenance. It has been widely used in cars, and there is a trend of gradually expanding its application in trucks.
