Description:
The bearing is used in wheel hub and serves as a precision interface between the stationary axle and the rotating wheel, enabling the transfer of both axial and radial loads while minimizing friction and wear. These bearings are enclosed in a protective housing which may include seals, grease, and other protective features to prevent contaminants like dirt, water, and debris from infiltrating the bearing and compromising its performance. The seals also retain lubrication, reducing friction and ensuring prolonged bearing life.
