Gearbox Oil Seal

Gearbox Oil Seal

This is a replacement gearbox oil seal specifically for use in Rex concrete mixer truck gearboxes. Oil seals are critical wear items that contain lubricating oil within the gearbox and prevent harmful contaminants from entering, which can cause premature wear to bearings and gears. This seal is essential for routine maintenance or during a complete gearbox rebuild to ensure leak-free operation and extend the service life of the equipment. It is designed to withstand the high rotational speeds and harsh, abrasive environment typical of concrete mixer operations.
