Oil Seal Hub Oil Seal For Sinotruck Howo Isuzu Truck

The function of the skeleton Oil Seal Hub Oil Seal For Sinotruck Howo Isuzu Truck is generally to isolate the components that need lubrication in the transmission components from the output components to prevent lubricating oil from leaking. It is usually used on rotating shafts and is a rotating shaft lip seal. The skeleton is like the steel bars inside the concrete components, which strengthens and enables the oil seal to maintain its shape and tension. According to the skeleton type, it can be divided into internal skeleton oil seal, external skeleton oil seal and internal and external exposed skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plates, with stable quality and long service life. Oil Seal Hub Oil Seal For Sinotruck Howo Isuzu Truck Widely used in automobile and motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels, etc.

1. Prevent sediment, dust, water vapor, etc. from intruding into the bearing from the outside;

2. Limit the leakage of lubricating oil in the bearing. The requirements for the oil seal are that the size (inner diameter, outer diameter and thickness) should comply with the regulations; it is required to have appropriate elasticity, which can properly clamp the shaft and play a sealing role; it must be heat-resistant, wear-resistant, good strength, and medium-resistant ( oil or water, etc.), long service life.

When using Oil Seal Hub Oil Seal For Sinotruck Howo Isuzu Truck rationally, you should pay attention to the following points:

(1) Shaft speed Due to design and structural reasons, high-speed shafts should use high-speed oil seals, and low-speed shafts should use low-speed oil seals. Low-speed oil seals cannot be used on high-speed shafts, and vice versa.

(2) When the ambient temperature is high, polypropylene or silicon, fluorine, or silicone fluorine rubber should be used. And should try to reduce the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.

(3) Oil seals with average pressure have poor ability to withstand pressure. The oil seal will deform when the pressure is too high. Under conditions of excessive pressure, a pressure-resistant support ring or reinforced pressure-resistant oil seal should be used.

(4) The degree of eccentricity in installation When the eccentricity of the oil seal and the shaft is too large, the sealing performance will become worse, especially when the shaft speed is high. If the eccentricity is too large, an oil seal with a "W" shaped section can be used.

(5) The surface finish of the shaft directly affects the service life of the oil seal. That is, the higher the smoothness of the shaft, the longer the service life of the oil seal.

(6) Note that there should be a certain amount of lubricating oil on the lip of the oil seal.

(7) Pay special attention to preventing dust from infiltrating into the oil seal.
