ON組合密封件-Parker - ON DOUBLE-ACTING ROD SEAL

Parker - ON HYDRAULIC ROD SEALING SET

The rod sealing set profile ON consists of a symmetric PTFE rod sealing ring and an O-Ring.

Profile ON is particularly suitable for rods in control cylinders, servi-assisted equipment, machine tools, quick acting cylinders or other in-house cylinder applications. An optimal sealing performance will be obtained if the rod sealing set is used in tandem with a double-wiper. The seal provides a double acting function.

Main advantages:

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.

Range of Application:

Working pressure        max. 400 bar

Working temperature     -30 / +100 °C

Surface speed           max. 4,0 m/s
