How Often Should Car Bearings Be Replaced?
1 Answers
There is no fixed replacement interval for car bearings; they only need to be replaced when damaged. Bearings in cars are maintenance-free and do not require grease replacement. The main function of wheel hub bearings is to bear loads and provide precise guidance for the rotation of the wheel hub. They withstand both axial and radial loads, making them a very important component. The wheel hub bearing unit has evolved from standard angular contact ball bearings and tapered roller bearings, integrating two sets of bearings into one. It offers advantages such as excellent assembly performance, elimination of clearance adjustment, lightweight, compact structure, high load capacity, pre-loaded grease for sealed bearings, elimination of external hub seals, and maintenance-free operation. These units are widely used in passenger cars and are gradually being adopted in commercial vehicles as well.
