90*145*10/16 – Suitable for heavy-duty drivetrains in Volvo Trucks and Volvo Buses.
Key Models: Classic heavy-duty truck series such as the Volvo F10, F12, F16, FL10, and FL12.
Application: Primarily used at the rear axle differential or reducer shaft end.
OEM Part Numbers: Volvo 1523239 or 1673701.
Functions of the Oil Seal:
1: Oil and Grease Retention: The differential housing is filled with high-viscosity gear oil. This oil seal fits tightly against the rotating driveshaft to prevent lubricant leakage, ensuring sufficient oil remains inside the differential for lubrication.
2: Dust and Water Protection: Trucks often operate in harsh road conditions. The seal features an external dust lip that blocks mud, dust, and rainwater from entering the differential, thereby preventing contamination of the gear oil.
3: Protection of Core Components: By maintaining a seal that prevents both internal leakage and external contamination, the seal protects differential gears and bearings from abnormal damage caused by oil starvation or dry friction, ultimately extending the service life of the vehicle's drivetrain.
