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 skeleton acts as a reinforcing steel bar in concrete members and keeps the shape and tension of the oil seal.
The FKM skeleton oil seal is made of high-quality fluororubber and steel plate with stable quality and long service life, and it is more heat resistant than the rubber oil seal, and it can also work in acid and alkaline.
It is widely used in automobile, motorcycle crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels, and other parts.
