VKBA5521 Wheel End Kit For BPW, ROR, GIGANT
The VKBA5521 Truck and trailer wheel bearings are used on the front wheels, rear wheels, drive axles, and trailer wheels of light trucks (Ford F-150), heavy trucks (Volvo FH), vans (Mercedes-Benz Sprinter), and trailers (single-axle trailers, container trailers).
The VKBA5521 bearing is a Wheel end kit with an inner diameter of 50/80 mm , an outer diameter of 110/130 mm, a width of 42.25/37 mm. It typically uses P0 (ABEC-1), P6 (ABEC-3) grade precision tolerances and Chrome Steel (Gcr15) rings, Chrome Steel (Gcr15) rolling mlement. It primarily bears Axial and radial loads, Double seals type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
VKBA5521 bearings ( 50/80 mm x 110/130 mm x 42.25/37 mm) have the advantages of Integrated, maintenance-free, high load capacity, low friction, and are therefore widely used in the Front wheels, rear wheels, drive axle and trailer wheel ends.
