Product Description

A wheel hub bearing, also known as a hub assembly or wheel bearing assembly, is a critical component found in automotive vehicles. It is responsible for enabling smooth and frictionless rotation of the wheels while supporting the weight of the vehicle.Hub bearing is the main role of bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important parts. The traditional automobile wheel bearing is 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.

Some hub bearings, particularly tapered roller bearings, may require preload adjustment or clearance adjustment during installation. Preload adjustment ensures that the bearings have a slight axial load to enhance stiffness and prevent excessive play. Clearance adjustment sets the optimal internal clearance to accommodate thermal expansion and contraction during operation.

 Hub bearings are typically pre-lubricated during the manufacturing process and sealed to retain the lubricant. The lubrication inside the bearing helps reduce friction, dissipate heat, and prevent premature wear. It is essential to use the recommended lubricant type and quantity specified by the manufacturer when replacing or servicing hub bearings.
