Automotive hub bearings

- Jul 02, 2019-

The main function of hub bearing (hub bearing) is to carry load and provide precise guidance for the rotation of the hub, which is a very important component, both axial and radial. Traditional automotive wheel bearings are made up of two sets of cone roller bearings or ball bearings, and the installation, oiling, sealing and clearance adjustment of the bearings are carried out on the automotive production line. This structure makes it difficult to assemble, cost and poor reliability in automotive production plants, and bearings need to be cleaned, oiled and adjusted when the vehicle is maintained at the service point. Hub bearing unit is based on the standard angle contact ball bearings and conical roller bearings developed, it will be two sets of bearings as a whole, with good assembly performance, can be omitted play adjustment, light weight, compact structure, load capacity, sealed bearings can be loaded in advance grease, omitted external hub seals and exempt from maintenance and other advantages, Has been widely used in cars, in heavy-duty vehicles also have a gradual expansion of the application of the trend.
