category of profile

machined or molded/standard/trade product.


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.
