派克OD型四氟组合密封件-OD HYDRAULIC ROD SEALING SET
The rod sealing set profile OD consists of a PTFE rod sealing ring and an O-Ring.
Profile OD is particularly suitable for rods in control cylinders, servo-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 acting wiper.
Main advantages:
Short assembled length according ISO 7425 /II
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.
Good back-transport of oil film due to special shape of sealing edge.
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
