OG型活塞组合密封-Parker - OG HYDRAULIC PISTON SEALING SET
Parker - OG SINGLE-ACTING PISTON SEAL
The piston sealing set profile OG consists of a PTFE-piston sealing ring and an O-ring.
Profile OG is particularly suitable for single-acting pistons in control cylinders, in servo controlled systems, machine tools and quick acting cylinders.
Main advantages:
Assembly on one-piece piston.
Short assembled length.
Minimal break-out and dynamic slide friction. Therefore no stick-slip. Steady movement is guaranteed even at low velocities.
Low wear.
High extrusion resistance.
High temperature resistance.
Compatibility with nearly all media due to the high chemical resistance of the rod sealing ring, and a wide selection of O-ring compounds.
Available in diameters up to 2500 mm.
Fit ISO groove 7425/l
Range of Application:
Working pressure max. 400 bar
