Black 80Mpa POM NBR Ok Compact Piston Seal For Excavator
OK
Purpose and performance:
OK type sealing rings are mainly used for piston sealing in heavy-duty hydraulic cylinders. These seals are suitable for working pressures up to 800bar, and in some cases higher. The sealing ring consists of two components, one is an open sealing ring with high hardness made of special material, and the other is a rubber rectangular ring that provides elasticity. Since the hydraulic cylinder sealing ring has an open structure, no auxiliary tools are required for installation. OK The sealing space is small and the groove is simple. It can resist impact loads, has no viscosity, and has excellent friction and sassafras resistance. Even after holding pressure for a long time, the friction in starting and running is very small.
