Dac38700037 Auto Hub Bearing

DAC38700037 Auto Hub BearingProduct Description
The hub bearing is primarily designed to provide load and provide precise guidance for the rotation of the hub. It is an extremely important component for both axial loads and radial loads. The traditional car wheel bearings are made up of two sets of tapered roller bearings or ball bearings, bearing installation, oiling, sealing and clearance adjustment are carried out in the car production line. This structure makes it difficult to assemble in the automobile production plant, high cost, poor reliability, and the maintenance of the vehicle at the maintenance point, but also need to clean the bearing, oil and adjust. Wheel bearing unit is in the standard angular contact ball bearings and tapered roller bearings developed on the basis of 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, for the seal bearing can be pre-loaded grease, omit the external hub seal and from maintenance, etc., has been widely used in cars, in the truck also gradually expand the application of the trend.

Maintenance attention
In the maintenance process, often found that some cars have a larger driving noise, check the tire without abnormal wear, in the lift on the wheel without significant abnormal sound. This phenomenon is often caused by the abnormal damage of the hub bearing, the so-called non-normal refers to the bearing damage caused by the installation. The front wheel bearings of the car are generally double row ball bearings, when the installation of the bearings if the use of hammer percussion installation, or in the bearing into the bearing seat through the pressure bearing inner ring way to install, will cause the side bearing raceway damage. When the vehicle is running when the noise, and when the wheels off the ground due to a better side of the raceway, and therefore can not hear the obvious noise. The correct installation operation is the key to long life of the bearing.
