description

most common guide ring for rod or piston application. used in many standard cylin- ders, majority of applications require split version for installation into closed housings, non split design available (bushings).

application
 

not bolded symbols; please consult our technical for application limitations

category of profile

machined or molded/standard/trade product.

 

advantages

as a non-metallic guide element for pistons & rods, for standardised housings, amongst others, according to ISO 10766

  • no seizure due to metal/plastic materials combina
  • medium load-bearing capacity.
  • chamfered profile edges prevent pressing of edge into the corner radii of the housing groove.
  • simple snap-in fitting.

 

application

earth moving equipment, industrial vehicles, agricultural machinery, cranes.
