LYHY ferris wheel bearing Wheel bearing (hub bearing)

Wheel bearing (hub bearing) primary role is to load and for the rotation of the hub to provide accurate guidance, both axial load and radial load, is a needle roller bearings‍ very important component. Traditional automotive wheel bearing is composed of two tapered roller bearings or ball bearing combination, bearing installation, oiled, sealed and adjust the clearance is carried out in the car on the production line. This structure makes it difficult in a car assembly plant, high cost, poor reliability, and maintenance car maintenance, but also the need for bearing cleaning, oiling and adjustment. Developed on the basis of the ferris wheel bearing unit is the standard angular contact ball bearings and tapered roller bearings on, it will be two sets of bearings as a whole, with good assembly performance can be omitted clearance adjustment, light weight, compact structure, load capacity large, sealed bearings can advance into the grease, Angular contact ball bearings‍ hub seals and maintenance advantages omitted from the outside wheel, has been widely used in cars, and in the truck also has a tendency to gradually expand the application.
