Function
Symmetrical piston/rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.
Features
c:: Symmetrical, single acting piston/rod seal, no interference on the ID or OD.
c:: Wider groove and softer lips compared to PRS06. c:: Excellent static and dynamic sealing performance. c:: Excellent performance in low pressure conditions. c:: Useable for long stroke lengths.
c:: Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.
Application
Reciprocating rods in hydraulic cylinders, plungers. Dynamic seals in hydraulic systems.
Max. pressure 400 bar, max. speed 10 m/s. Tandem arrangement possible.
Installation
Snap-in installation.
Attention: PTFE glide rings needs calibration after installation!
