Product Description
The hub bearing is primarily designed to provide load and precise guidance for the rotation of the hub. It is an extremely important component for both axial loads and radial loads. Traditional car wheel bearings consist of two sets of tapered roller bearings or ball bearings, with installation, oiling, sealing, and clearance adjustment performed on the production line. This structure makes it difficult to assemble in the automobile production plant, leading to high costs, poor reliability, and maintenance challenges. The wheel bearing unit is developed based on standard angular contact ball bearings and tapered roller bearings, combining two sets of bearings into one. It offers good assembly performance, eliminates the need for clearance adjustment, is lightweight, compact, has a large load capacity, and can be pre-lubricated, eliminating the need for external hub seals and regular maintenance. It is widely used in cars and gradually expanding its application in trucks.
Maintenance Attention
During maintenance, it is often found that some cars have excessive driving noise. Checking the tires shows no abnormal wear, and lifting the wheels does not reveal significant noise. This phenomenon is usually caused by abnormal damage to the hub bearing, which refers to damage due to improper installation. Front wheel bearings are generally double-row ball bearings. If installed using hammer percussion or pressure through the inner ring, it may cause damage to the raceway. When the vehicle is running, the noise may not be noticeable when the wheels are off the ground, but proper installation is crucial for the bearing's longevity.
