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.
- Double acting wiper that is only used in old machineries anymore. For new
constructions WR11 or WR12 is recommended.
- Special designed housings required.
- Pressure from the trailing side should be avoided.
Application
Reciprocation rods in old hydraulic cylinders, plungers.
Max. pressure 0 bar, max. speed 4 m/s.
Installation
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%.
