What is the oil seal

Oil seal is used to seal oil ( Oil is the most common type of liquid substances in the transmission system, also refers to the general liquid substance) Mechanical components, it will need lubricating parts and transmission parts output component segregation, unapt let lubricating oil leakage. Static seal and dynamic seal ( General reciprocating motion) Seal called sealers. The representative of oil seal in the form of TC oil seal, this is a kind of rubber coated with the full spring lips oil seal, the general said oil seal often referred to as the TC skeleton oil seal. Oil seal is what material? Oil seal is rubber material. Oil seal is mainly used in two joint parts of the lubrication parts, to prevent oil leakage, such as crankshaft oil seal, half shaft oil seal, gearbox oil seal, etc. Skeleton oil seal is? Skeleton oil seal is a typical representative of oil seal, general said oil seal is refers to the skeleton oil seal. Generally is the role of oil seal driving part need lubrication components and output components in isolation, not let lubricating oil leakage. Skeleton is like the inside of the concrete members reinforced, have the effect of strengthening, and makes the oil seal can keep shape and tension. According to the structural form can be divided into single lip skeleton oil seal and double lip skeleton oil seal. Lips skeleton oil seal deputy lip dustproof effect, to prevent external dust, impurities and so on into the machine inside. According to the skeleton skeleton oil seal type can be divided into the package, exposed skeleton oil seal and prefabricated oil seal. According to the working conditions can be divided into rotation skeleton oil seal and return type skeleton oil seal. Used for gasoline engine crankshaft, diesel engine crankshaft, transmission, differential, shock absorber, engine, axle parts, etc. Skeleton oil seal is generally what material skeleton oil seal is generally divided into: nitrile rubber ( NBR） , fluorine rubber ( VITON） , silica gel, SIL) , nylon ( PA） These four were the most common material, of course the PTFE teflon skeleton oil seal, oil seal and so on.
