Introduction

Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, in a truck also has a tendency to gradually expand the application.

Main Function

The main role of hub bearings is to bear weight and provide accurate guidance for the rotation of the hub, it bears axial and radial loads, is a very important part. The 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 carried out on the automobile production line. This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the maintenance of the car in the repair point, the bearing needs to be cleaned, oiled and adjusted.

Application

Hub bearings are used with car wheels.
