Description-Oil Seal:
Oil seals - often called grease, fluid or dirt seals - close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contaminants from entering machinery, particularly in severe environments.
The function of the skeleton oil seal is to isolate the parts that need lubrication from the output parts in the transmission parts, so as not to let the lubricating oil leak. It is usually used in the transmission parts.
The rotary shaft is a rotary shaft lip seal. The skeleton acts as a reinforcing steel bar in concrete members and keeps the shape and tension of the oil seal. According to the skeleton type, it can be divided into internal skeleton oil seal, external skeleton oil seal, and internal and external skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life. Widely used in automobile, motorcycle crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels, and other parts.
