Oil seal

classification

Oil seals are generally divided into single type and assembled type. The assembled type allows the skeleton and lip material to be freely combined and is generally used for special oil seals.

Oil seals can be classified into various forms and different names based on their sealing function, characteristics, structural types, working conditions, and sealing mechanisms. However, it is customary to refer to rotating shaft lip seals as oil seals, and static seals and dynamic seals (usually reciprocating motion) as seals.

purpose

Engine: crankshaft - crankshaft front and rear oil seals valves - valve oil seals (engine repair kit O-ring) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal...); Camshaft - Camshaft oil seal; Transmission: Transmission - front and rear oil seals, shift lever oil seals (transmission repair kit O-ring) (transfer case - front and rear oil seals); Rear axle: Half axle - Rear axle oil seal differential - (front) rear angle arrow oil seal Rear wheel oil seal Front wheel oil seal Steering gear oil seal (steering gear repair kit O-ring) Direction booster oil seal (front half axle oil seal).

Any part of the operating body box that has liquid lubricating oil and is connected to the outside requires oil seals. Some are rubber, some are metal, and most are steel reinforced rubber, such as crankshaft rear oil seal, transmission front and rear oil seal, left and right half shaft oil seal, main reducer front oil seal, air compressor crankshaft oil seal, etc.
