SO 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.
Construction machinery, forklift-trucks, injection moulding machines, Agricultural machinery and standard cylinders.
Generally, wiper can be easily fitted into the closed housing by deforming into a kidney shape.It is very important that the assemble tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
SO WRM wipers are single action and can be used with combination of all rod sealing elements. SO WRM wipers can be produced on request in FPM material for special applications that require high temperatures.
