TC Skeleton Oil Seal

Product Description:


TC oil seal is a mechanical element used to seal oil, which isolates the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. The seals used for static seals and dynamic seals (generally reciprocating motion) are called seals. The skeleton oil seal structure consists of three parts: oil seal body, reinforced skeleton, and self-tightening coil spring. 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.


Working machinery and equipment, engineering machinery and equipment, means of transportation, conveying equipment, machinery manufacturing, agricultural machinery, etc. Widely used in automobiles, motorcycles, crankshaft, camshaft, differential, shock absorber, engine, axle, front and rear wheels and other parts.

Installation Recommendation:

Reasonable use of oil seals, should pay attention to the following points:
(1) the speed of the shaft, due to the design and structural reasons, high speed shaft should use high-speed oil seal, low speed shaft using low speed oil seal, can not use low speed oil seal for high-speed shaft, and vice versa.
(2) when environment temperature is high, polypropylene, silicon, fluorine and fluorosilicone rubber should be chosen. And try to lower the oil temperature in the tank. When the temperature is too low, cold resistant rubber should be used.
(3) the pressure of the oil seal is poor, and the oil seal will deform when the pressure is too great. Under the condition of excessive pressure, the pressure bearing ring or the strengthened pressure seal shall be adopted.
(4) the eccentricity of the installation, when the oil seal and the shaft are too eccentric, the sealing performance will become worse, especially when the shaft speed is high. If the eccentricity is too large, the oil seal with 'W' cross section can be adopted.
(5) the surface smoothness of the shaft directly affects the service life of the oil seal, that is, the shaft has a high degree of finish, and the service life of the oil seal will be longer.
(6) pay attention to a certain amount of lubricating oil in the lip of the oil seal.
(7) special attention should be paid to preventing dust from being immersed in oil seals.
