Wiper Ring XSWR13

Function:
Wipers are designed to keep dust, dirt, sand and others off the rod and the
sealing and guiding elements, avoiding abrasive damage caused by external
contamination.

Features:
  • The profile is designed with two geometric different lips for wiping off any dirt on the rod and to reduce the residual oil film on the medium side.
  • The wiper consists of a PTFE wiping part and an O-Ring as preload element, maintaining contact pressure on the rod.
  • Due to the use of an O-Ring the wiper is able to compensate deflections of the rod.
  • Mainly used in combination with rod seal RS09B.
  • Pressure should be limited to 15bar.
  • For housings acc. to ISO 6195 Type D.
