Quick LINKS
AS - METALLIC WIPERS
Metal-cased wipers are a single acting seal ensuring that foreign particles are not introduced into the hydraulic systems , avoiding wear and damage to all the internal components including seals. They also enable the rod to be well lubricated. Metallic wipers are single acting and can be used with combination of all rod sealing parts.
ADVANTAGES
- Superior wiping performance
- Axially open easy-construction groove
- Used in heavy conditions by the good mechanical properties of PU material
- Secure seating , press fitting into the housing
- Space-saving construction
APPLICATIONS
Light and medium duty construction machinery , fork-lift trucks , agricultural machinery , support cylinders and standard cylinders.

INSTALLATION
Wiper is pressed into axially open housings. Special equipment should be used during this process. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
