Wheel hub bearing units enable wheels to turn freely and smoothly and also have a critical role in vehicle safety. They incorporate precision bearings and sensors, and increasingly include special coatings and greases for higher performance. We offer a range of hub bearing units that are applicable to different vehicle types. One design, for instance, features a double row angular contact ball bearing with matched rings and ball-sets to provide the required axial clearance. Variants of this incorporate a flange with the bearing outer ring, while another also has a flange in the rotating ring. There are other refinements to our range, including a unit with improved ABS and TCU sensors. Another is an anti-corrosion coating that simplifies disassembly of the bearing from the knuckle and rim.
