We are supplying professional oil seals with various types and automotives/tractor /truck/ trailer oil seals. Custom oil seals can be made with customs' request. Oil seal consists of three parts: the seal body, strengthen the skeleton and the self-tightening spiral springs.The role of oil seal of the transmission components in general is in need lubrication components and parts output isolation, and typically used for rotating shaft is a rotary shaft lip seal. It can be divided in the seal, the outer seal, the inner and outer exposed skeleton oil seal.
