O-rings, oil seals, U-seals
Reinforced seals prevent leakage of grease, provide separation of space protects the mechanism from getting dust, maintain the pressure difference between different parts of the mechanism.
Hydraulic cuffs made of polyurethane (PU), used to prevent space between the cylinder and the piston of hydraulic devices. These cuffs are widely used as substitutes for rubber products, especially in hydraulic systems in which conventional rubber cuffs (NBR) are not possible chemical brittleness.
This is due to the unique properties of polyurethane: water, acids, resistance to oil. Wide operating temperature range from -30 ° C to + 100 ° C
