Auto Parts Wheel Hub Flange Hub Bearing Unit Assembly

Wheel Hub Flange Hub Bearing

Wheel hub bearing is the main function of bearing and provide accurate guide to the rotation of the wheels. It handles axial load and radial load, making it a critical component for vehicle safety and performance. Traditional car wheel bearings were combined by two sets of tapered roller bearings or ball bearings. However, modern hub bearing units integrate these into a single assembly for better reliability and easier installation.
