　　Oil seal is a general term for seals that prevent the leakage of lubricating oil. Oil seal achieves the sealing effect by contacting the rotating shaft with a very narrow sealing contact surface (less than 0.5mm) under a certain pressure and under the action of liquid lubrication. As an elastomer seal, the cross-sectional shape and clamping spring of the oil seal make the lip have a good following compensation performance to the shaft, so that a good sealing effect can be obtained with a small lip radial force.

　　Even if the selection of oil seal is correct in the early stage, and the groove size design of oil seal installation position is reasonable, it can not guarantee 100% of the expected function of oil seal. Because the installation operation method, installation direction and installation tool selection of oil seal are also very important. Next, I will introduce the correct method of installing oil seal, please read carefully.

　　The correct installation method of oil seal are as follows:

　　Before installing the oil seal, check whether there are dust and impurities on the surface and lip of the oil seal, to avoid damaging the lip and shaft during the shaft movement, causing leakage.

　　Before installing the oil seal, check whether there are rust-proof oil or dust and other foreign matters on the surface of shaft or cavity, if any, please clean them.

　　Before installing the oil seal, check whether there are burrs or chamfers on the surface of shaft or cavity, to avoid damaging the lip during installation.

　　When installing the oil seal, apply lubricating oil or grease on the outer diameter and lip of the oil seal, to reduce friction and wear.

　　When installing the oil seal, pay attention to the installation direction of the oil seal, and make the sealing lip face the sealing medium side.

　　When installing the oil seal, use special fixtures or pressure machines to avoid tilting or deformation of the oil seal.

　　When installing the oil seal, place the oil seal horizontally on the cavity hole and press it evenly, to avoid forcing or knocking.

　　These are some of the main points of the correct installation method of oil seal. The oil seal installation personnel must follow the correct installation method, use special handling fixtures, assembly fixtures, and avoid using wrong methods, so that the oil seal can play its expected role and function.
