Wiper Ring XSWR15

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 two O-Rings 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 XSRS09B.
  • Pressure should be limited to 15 bar.
  • For housings acc. to ISO 6195 – Type D.
