VSO WRM is a single action wiper ensuring that foreign particles are not introduced into the hydraulic systems, avoiding wear and damage to all the internal components including seals.

PRODUCT ADVANTAGES

  • Very good wiping performance
  • Simple, easy-construction groove
  • Wide range of dimensions
  • No twisting in the housing
  • Easy installation
  • Specially designed to prevent big particles to go into the system
  • Used in heavy conditions by the good mechanical properties of Polyurethane material.  

APPLICATION
Construction machinery , forklift-trucks , injection moulding machines , agricultural machinery and standard cylinders

INSTALLATION
Generally , wiper can be easily fitted into the closed housing by deforming into a kidney shape. 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.
