Special Features: Material : polyacetal glass fibre einforced Velocity : reciprocating to 0.8 m/s Temperature : -40 to +110 °C Guide rings PWR and RWR filled polyacetal successfully reduce metallic contact between sliding parts, i.e. piston rod and piston in cylinder bore. In the case of intermediate duty applications, they represent an alternative of phenolic fabric or polyester fibre wear rings. They are supplied in slotted design with a cut at an angle or straight splitting. Very good shear characteristics, no stick slip effect Exact tolerances through injection process No swelling Avoids metallic contact of sliding parts Easy to manufacture the groove geometry Easy snap-in assembly into the groove Alternative to PTFE, Phenolic fabric or Polyester polyester fiber, wear and guide rings on a different price basis 195 PWR, RWR Guide Rings
