Product Name:

Trailer Axle Oil Seal 76.26x95.27x17 JAC / C&C Truck High temperature Resistant Oil Seal

Oil Seal Stucture:

Oil Seal Type:

The shaft skeleton oil seal is an essential component in lubricated rotating motion.

SPS rotating skeleton oil seal is after years of practice, the use of advanced technology processing.

A, sealing lip:

Sealing lip oblique wedge shape, sealing fluid role. Standard material is nitrile rubber, other rubber materials can be selected according to requirements. Sealing lip can be either injection molding or mechanical cutting.

B, self-tightening spring "provides radial compression force. Material: phosphating C72 spring steel (standard) or AISI302 stainless steel (for acid fluids and water)

C, metal skeleton: fixation and support. Thin steel is usually used, but stainless steel may be used if required.

D. Dust proof lip: dust proof.

Selection of rubber materials

NBR70- NITrile butadiene rubber has good properties of mineral oil and edible oil. Good wear resistance, bending resistance, aging resistance, elastic rubber body universal material. When the temperature is not too high, it can also be used with low concentration of inorganic acids and salts.

Si70-silicic acid has lower physical/chemical properties (ductility, tensile strength, etc.) than other rubbers, but it has good compressibility and low coefficient of friction, which is very important in some cases. Good resistance to mineral oil, but poor resistance to gasoline, acid and fluoride agent.

Fkm70-fluorine rubber has good physical properties and high temperature resistance (instant up to 250 degrees). It is a good material for oil, fuel, various solvents and chemical substances. Not recommended in the presence of low molecular lipids, ethers, ketones, amines. In some conditions, other elastomers are easy to aging or loss, but fluorine rubber must be considered.
