What is the oil seal of deep groove ball bearing?
Oil seal is used to seal oil (oil is the most common liquid substance in the transmission system, also generally refers to the general meaning of liquid substances). It separates the parts that need lubrication in the transmission parts from the output parts, so as to prevent the leakage of lubricating oil. Static seal and dynamic seal (general reciprocating motion) with seals called seals. The representative form of oil seal is TC oil seal, which is a double lip oil seal with self tightening spring completely covered by rubber. Generally speaking, oil seal usually refers to this kind of TC framework oil seal.
What material is the oil seal?
The oil seal is made of rubber. Oil seal is mainly used in the joint of two lubricating parts to prevent oil from seeping out, such as crankshaft oil seal, axle shaft oil seal, transmission case oil seal, etc.
What is the skeleton oil seal?
Skeleton oil seal is a typical representative of oil seal. Generally speaking, oil seal refers to framework oil seal. The function of oil seal is to isolate the parts that need to be lubricated in the transmission parts and the output parts, so as not to let the lubricating oil leak. The skeleton is like the steel bar in the concrete component, which plays a reinforcing role and keeps the shape and tension of the oil seal.
According to the structure, it can be divided into single lip framework oil seal and double lip framework oil seal. The secondary lip of double lip framework oil seal plays a dust-proof role to prevent external dust and impurities from entering into the machine. According to the framework type, it can be divided into inner framework oil seal, exposed framework oil seal and assembled oil seal. According to the working conditions, it can be divided into rotating framework oil seal and reciprocating framework oil seal. For gasoline engine crankshaft, diesel engine crankshaft, gearbox, differential, shock absorber, engine, axle and other parts.
What material is the framework oil seal in general?
The general materials of framework oil seal are NBR, Viton, SIL and PA, which are the most common materials. Of course, there are PTFE Teflon oil seal, outer framework oil seal, etc.
