High Load Bearing Differential Housing HD95129320077 Multi-Hole Flange Design With Integrated Spline Hub For Commercial Vehicle Drive Axle

Product Description

HD95129320077 differential housing assembly is the core load-bearing shell component of heavy truck drive axle differential system. It serves as the mounting carrier for differential gears, side gears, bearings and pin shafts, bearing huge radial and axial torque during vehicle full-load operation, and evenly distributes driving torque to left and right driving wheels. The product adopts integrated casting and one-time precision machining molding, with standard flange bolt holes and internal spline hub fully matched with original axle parts, realizing seamless assembly during axle maintenance and overhaul.

Key Product Advantages

• Integral high-strength alloy steel casting + overall quenching heat treatment, strong torsional resistance and anti-fatigue performance, no cracking or deformation under long-term heavy load climbing and bumpy road driving.
• Multi-layer stepped flange layout with evenly distributed precision machined mounting holes, uniform stress distribution during assembly, effectively avoiding bolt loosening and oil leakage.
• Internal multi-tooth involute spline hub processed by precision broaching, high matching accuracy with transmission shaft spline, stable power transmission without tooth jumping or abnormal noise.
• Reserved standard sealing groove inside the shell, matched with high-temperature resistant oil seal to prevent gear lubricating oil leakage under high-speed operation of the axle.
• Strict dimensional tolerance control of all installation surfaces, completely interchangeable with original differential components, no secondary turning or grinding required during maintenance assembly.
