F 300021 Wheel End Module
The F 300021 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 F 300021 bearing is a Wheel end module with an inner diameter of 70 mm , an outer diameter of 178 mm, a width of 140 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.
Interchange code: SKF 0144D-VU9001, SKF BTF 0144D, SKF BTF 0144D-VU9001, SKF VU9001, Fersa F 300021
F 300021 bearings ( 70 mm x 178 mm x 140 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.
