- Mar 01, 2018 -

Hub bearing (hub bearing) is the main function of load-bearing and for the rotation of the wheel to provide accurate guidance, which both under axial load and bearing radial load, is a very important component. The traditional automobile wheel bearings are made of two sets of tapered roller bearings or ball bearings, and the adjustment of bearing installation, oil coating, seal and clearance are carried out on the automobile production line. This kind of structure makes it difficult to assemble in the automobile production plant, the cost is high, the reliability is poor, and when the vehicle maintains the maintenance point, the bearing also 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, it will be two sets of bearings as a whole, with good assembly performance, can be omitted clearance adjustment, light weight, compact structure, large load capacity, for sealed bearings can be loaded in advance grease, the external hub to omit the sealing and maintenance and other advantages, has been widely used in cars, in the truck has gradually expanded the application trend.
