Mining Seal XSW51
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 interference on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
- Additional sealing on the housing face.
- Sharp wiping lip to ensure any dirt is wiped off properly.
- Secundary lip for stabilizing and reducing the residual oil film.
- Pressure from the trailing side has to be avoided.

Snap-in installation.
When the cylinder can not be dismantled, the wiper can also be installed in cut version. In this case the diameter should be increased by 2-3%.
