A1663340206 Front Wheel Bearing Hub Assembly VKBA 6784 auto bearing BSSD

Car wheel hub bearing‌ is a type of car bearing. Its main function is to bear load and provide precise guidance for the rotation of the wheel hub. It can bear both axial load and radial load. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. This structure is difficult to assemble on the automobile production line, has high costs, and has poor reliability. The wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. The two sets of bearings are integrated into one, which has good assembly performance, can omit clearance adjustment, is light in weight, has a compact structure, and has a large load capacity. Large, sealed bearings can be filled with grease in advance, eliminating the need for external hub seals and being maintenance-free.
