Auto parts Front Wheel Hub Unit Hub bearing for HILUX FORTUNER 90369-T0003
Traditional bearings for automobile wheels are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of bearings are all carried out on the automobile production line. This structure makes it difficult to assemble in automobile factories, with high cost and poor reliability. In addition, the bearings need to be cleaned, oiled and adjusted during maintenance at maintenance points.
Hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It integrates the two sets of bearings into a whole and has the advantages of good assembly performance, omitting clearance adjustment, light weight, compact structure, large load capacity, pre-loading grease for sealing bearings, omitting external hub seal and avoiding maintenance, etc. It has been widely used in cars and has a trend of gradually expanding application in trucks.
