Application and properties
Apply to the working condition of fast speed, high pressure, and the necessary pressure keeping. Recommended for double-acting pistons as piston-type energy storage, supporting cylinder and positional cylinder. Double safety with low friction and high elasticity, good dynamic and static sealing performance, larger extrusion clearances can be allowed, at the same time with the function of holding pressure, less leakage in the hydraulic cylinder. Simple groove, small installation space, excellent sliding performance, no crawling phenomenon.
Sealing ring: filled PTFE
O-Ring: NBR / FKM
X-Ring: NBR / FKM
