Product Description
Product Introduction
This rear axle gearbox housing cover is a precision-cast structural component, manufactured from high-strength ductile iron (QT450-10) through high-precision mold casting and CNC finish machining. Its integrated stepped cylindrical structure features a precision-machined inner bore for bearing positioning, a flat sealing flange with evenly distributed bolt holes, and reinforced ribbing at stress-bearing points to enhance structural rigidity. The cover undergoes normalized heat treatment to eliminate casting internal stress and prevent deformation under heavy loads, with a corrosion-resistant black oxide coating on the surface for long-term protection in harsh working conditions. The precision-machined sealing surface ensures a perfect fit with the differential housing, matching with OE-spec gaskets or oil seals to achieve zero leakage of lubricating oil.
Core Function
-
Seals the open end of the rear axle differential housing, forming a closed lubrication cavity to prevent the leakage of gear oil and the ingress of external dust, water and impurities.
-
Provides precise axial positioning and support for the differential side bearing, maintaining the running clearance and concentricity of the differential gear set.
-
Bears and disperses the axial thrust generated by the differential during operation, preventing bearing displacement and ensuring stable meshing of internal gears.
-
Serves as an auxiliary mounting base for rear axle accessories such as the speed sensor, with reserved mounting holes to meet the functional configuration requirements of heavy-duty trucks.
-
Realizes direct OE replacement, with full compliance of dimensional parameters and mounting standards to ensure quick assembly and consistent performance with the original rear axle system.
