oil seals

Engine crankshaft bearing parts are mostly seals, rubber seal installation.Its main function is to prevent leakage of oil, and prevent the dust, filth from invading as machines internal sediment, is a kind of high technical requirements of precision products.

4 Correct installation oil seal

3 Choose materials used in rubber lips conditions can play a role

2 On the surface, such as shaft roundness, beating the axial load, the quantity, the impact of the deformation of dynamic control limits in, so as to establish and maintain satisfaction of oil film.

1 According to the standards specified tolerances manufacturing  oil seal

Two main lips mouth adopts hydrogenated butadiene acrylonitrile rubber (HNBR) and butadiene acrylonitrile rubber (NBR) to meet the material composition, oil resistance, heat resistance, abrasion resistance, corrosion resistance, resistance to deformation and performance requirements.Oil seals is through the control lips mouth and cooperation between the interference quantity, and the static and dynamic conditions can prevent leakage, simultaneously must meet the following conditions:

It's working reliability and service life, is the measure of hydraulic system is an important index.
