Installation & Usage Guidelines

• Cleanliness is Key: When replacing Sinotruk spare parts, especially bearings, ensure the housing and shaft are free of contaminants. Even microscopic dust can degrade the 0735.303.332 bearing’s lifespan.

• Proper Lubrication: Use the manufacturer-recommended heavy-duty grease or gear oil. Incorrect viscosity can lead to overheating at high speeds (RPM).

• Adjustment: Tapered roller bearings require proper internal clearance adjustment during installation. Ensure the preload is set according to the Sinotruk service manual to avoid excessive friction or vibration.

• Inspection: Check the bearing raceway for signs of pitting or spalling during routine maintenance intervals (every 20,000 – 50,000 km depending on usage).
