Oil Seal

Oil Seal
Oil Seal

An oil seal is a lip-type seal designed for rotating shafts, featuring an internal metal skeleton and a garter spring for support and reinforcement. Primarily installed in the bearing housing or drive end of a pump, it prevents lubricant or grease leakage while blocking external dust, moisture, and contaminants from entering the bearing cavity, serving as a protective barrier to ensure the smooth operation of the pump drive system.
