The wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings into one. It has the advantages of good assembly performance, no need for clearance adjustment, light weight, compact structure, large load capacity, grease can be pre-loaded for sealed bearings, no external wheel hub seals and no maintenance. It has been widely used in cars and there is a trend of gradually expanding its application in trucks.
The Wheel Hub Bearing is an essential part of your vehicle’s wheel system, playing a vital role in ensuring smooth rotation and proper wheel alignment. It is designed to support the vehicle's weight while enabling the wheels to rotate with minimal friction. Made with high-quality materials, this bearing provides long-lasting durability and reliability, even under heavy use.
The main components of a heavy-duty truck wheel hub bearing include a large inner ring, a large outer ring, rolling elements (rollers), a cage, a locking mechanism, a heavy-duty truck chassis (ball housing), and bolts. Due to the assembly requirements and characteristics of automotive wheel hub bearings, a double-row tapered roller bearing is required to withstand both axial and radial loads.
