Guide Ring XSBWR04

Function:
Guiding elements are designed to prevent metal to metal contact between components of hydraulic systems e.g. piston and cylinder barrel or shaft and cylinder head.

Features:
  • Normally cut at an angle for easy installation, but also available as non-split version.
  • For use in rod applications.
  • Design combines guiding and backring function.
  • Low dynamic friction.
  • Low break-away forces after long standstills.

Application

  • Reciprocating rods in hydraulic cylinders, plungers, etc.
  • Max. speed 4 m/s, radial loads max. 70 N/mm2.
