Supplied By: Shannxi Bernard Machinery Co., Ltd.

The HD90129320370 Tapered Roller Bearing (31316X2) is an original factory component engineered for the main reducer assembly in HANDE heavy-duty drive axles (specifically HDZ440 & HD469 platforms). Positioned on the input shaft / bevel gear pinion assembly, this high-precision bearing plays a crucial role in maintaining pinion gear alignment under severe torque conditions.

Its high taper angle design allows it to support heavy combined radial loads and heavy unidirectional axial thrusts generated by high-torque spiral bevel gears, ensuring quiet drive axle performance, smooth torque transmission, and minimal mechanical friction.

Key Features & Technical Advantages

• Heavy-Duty High-Taper Angle Design (313 Series): Specially optimized roller-to-raceway contact angle engineered for high-thrust drive axle applications, preventing axial play under heavy acceleration and retarder braking.

• 100% Genuine HANDE OEM Specification: Sourced from original supplier channels, adhering to strict precision limits (P6 / P6X quality class), guaranteeing silent operation and zero premature spalling.

• Superior Load Capacity & Thermal Stability: Manufactured with high-purity fatigue-resistant bearing steel and heat-treated for operation in high-temperature axle oil baths.

• Exact Dimensions (80x170x53 mm): Direct 1:1 drop-in replacement for SHACMAN X6000 / X5000 drive axle bevel gear maintenance.

Common Symptoms of Wear & Maintenance Tips

1. Drive Axle Whine / Grinding Noise: A high-pitched whining noise from the rear differential that changes during acceleration or coasting usually indicates worn roller surfaces or pitted raceways on the 31316X2 bearing.

2. Bevel Gear backlash Instability: Excessive axial end-play in the input shaft causes misalignment between the crown wheel and pinion, leading to rapid gear tooth wear.

3. Preload Adjustment: Always adjust the bearing preload strictly according to HANDE HDZ440 service manuals when rebuilding the main reducer assembly.
