NISB is a double action metal wiper ensuring that foreign particles do not penetrate into the hydraulic systems, avoiding wear and damage to all the internal components including seals.
Light and medium duty construction machinery, forklift-trucks, agricultural machinery,support cylinders and standard cylinders.
NISB 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.
NISB wipers are double action and can be used with combination of all rod sealing elements.
