What is the oil seal

Oil seal is a mechanical component used to seal oil (oil is the most common liquid substance in the transmission system, also refers to the general liquid substance). It isolates the parts of the transmission parts that need to be lubricated from the output parts, so as not to let the lubrication Oil leaks. Seals for static and dynamic seals (generally reciprocating) are called seals. The representative form of the oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. Generally speaking, the oil seal often refers to this tc skeleton oil seal.


What material is the oil seal?
The oil seal is made of rubber. The oil seal is mainly used in the joint parts of two lubricating parts to prevent oil leakage, such as crankshaft oil seal, semi-shaft oil seal, transmission shell oil seal and the like.


What is the skeleton oil seal?

The skeleton oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts of the transmission parts that need to be lubricated from the output parts, so as not to let the lubricating oil leak. The skeleton acts like a reinforcing bar inside the concrete member, which acts to strengthen and maintain the shape and tension of the oil seal.

According to the structure, the single lip skeleton oil seal and the double lip skeleton oil seal can be divided. The secondary lip of the double-headed skeleton oil seal acts as a dustproof to prevent dust and impurities from entering the inside of the machine. According to the skeleton type, it can be divided into an inner skeleton oil seal, an exposed skeleton oil seal and an assembled oil seal. According to working conditions, it can be divided into rotating skeleton oil seal and reciprocating skeleton oil seal. Used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles, etc.


What is the general material of the skeleton oil seal?
The general materials of the skeleton oil seal are divided into: nitrile rubber (NBR), fluororubber (VITON), silica gel (SIL), nylon (PA). These are the most common materials, of course, PTFE Teflon oil seals, and Skeleton oil seals and more.
