China factory directly supply right front hub wheel bearing Dac28580042 Dac286142 Dac39530037 OEM Bearing Wheel Bearing
Bearings used in automobile, including wheel hub bearing, gearbox bearing, air conditioning compressor bearing, separation bearing, etc 

The main function of hub bearing is to bear load and provide accurate guidance for the rotation of hub. It bears both axial load and radial load, so it is a very important part. The 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 carried out on the automobile production line. This kind of structure makes it difficult to assemble, high cost and poor reliability in the automobile factory, and when the automobile is in the maintenance point, it also needs to clean, oil and adjust the bearing. Hub bearing unit is developed on the basis of standard angular contact ball bearing and tapered roller bearing. It integrates two sets of bearings. It has the advantages of good assembly performance, omitting clearance adjustment, light weight, compact structure, large load capacity, pre loading grease for sealed bearings, omitting external hub sealing and avoiding maintenance. It has been widely used in cars, There is also a trend to gradually expand the application in trucks.
