Seal
UN Seal is used to seal oil (transmission oil is the most common liquid substance, also refers to a liquid substance meaning general) mechanical components, transmission components will need to lubricate parts and component output isolation, and will not let lubrication oil leakage. Static seal and dynamic seal (general reciprocation) seals called seal. TC is the representative form of seal oil seal, which is self-tightening spring with one rubber seal lips completely covered, the general said oil seal often refers to this tc oil seal.

Oil seal (oil seal) is generally customary appellation seals, simply put this is that oil seal.
Seal is generally divided into haplotypes and assembly type, assembly-type skeleton and lip material may be freely
Combination, generally used for special seals.

Seal seal, characteristics, structure type, job status and the like from the sealing mechanism can be divided into many forms and different names, but the habit is generally called the rotary shaft lip seals oil seals, static seal and dynamic seal (general reciprocation ) seals called seal. TC is the representative form of seal oil seal, which is a rubber seal lips completely covered with a self-tightening spring, the general said, often refers to this tc oil seal oil seal, oil seal skeleton diagram shown in Figure:
Seal material

Seal materials are commonly used: nitrile rubber, fluoro rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene and the like. When selecting seal material must be considered material to the work of media compatibility, the ability to follow the operating temperature range of adaptability and high-speed rotation of the lip of the rotary axis. When the general work of its seal lip higher than the operating temperature of the medium temperature 20 ~ 50 ℃, should pay attention to when selecting seal material. For more details, please refer to: rubber types and characteristics. Material scope seal and seal using about: material is a nitrile rubber (NBR) is -40 ~ 120 ℃, Aggreko rubber (ACM) -30 ~ 180 ℃, Viton (FPM) -25 ~ 300 ℃.
Feature purpose
Engine: crankshaft – Front crankshaft rear oil seal valve – Valve seal (engine repair kit o-ring) (distributor seals, water pump seals, balance shaft seals, pump seals …); Camshaft – camshaft oil seal ; transmission: transmission – front derailleur, rear oil seal gearshift lever seal (o-ring transmission repair kits) (splitter – front splitter, rear oil seal); rear axle: axle – rear axle differential oil seal pacer – (front) rear wheel angle vector seal rear oil seal oil seal oil seal direction (the direction of repair kits o-ring) direction booster seal (front axle seal).
Those who work inside the body of liquid lubricants yet connected to the external parts are required seal. Some are rubber, some are metal, mostly steel reinforced rubber, such as the crankshaft rear oil seal, front and rear gearbox oil seal around axle seal, before the final drive oil seals, air compressor crankshaft oil seal
