This tapered roller bearing is a vital component in the drivetrain or wheel hub assembly of Volvo dump trucks, engineered to manage significant radial and axial loads. It is manufactured to precise tolerances for smooth operation and extended service life, unlike a worn bearing that would introduce excessive friction and play. Operators may experience increased noise, vibration, or difficulty in steering and drivetrain performance when this bearing begins to fail.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Early signs of a failing tapered roller bearing include audible humming or grinding noises from the affected axle or transmission, particularly under load or during turns. If ignored, the bearing can overheat, seize, and cause severe damage to the shaft, housing, and surrounding components, potentially leading to a loss of drive or steering control. Continued operation risks extensive drivetrain damage.
Thoroughly clean the bearing housing and shaft before installation to ensure a precise fit and prevent contamination. Apply the specified lubricant evenly and avoid hammering or forcing the bearing into place.
When replacing a tapered roller bearing, it is essential to inspect the axle shaft or transmission gear, as well as the seals, for any signs of wear or damage.
