Hydraulic and Pneumatic Seals...since 1975
VNISO is a double acting rod seal and rod scraper combination specially designed not to require additional element for axial fitting within the housing.
PRODUCT ADVANTAGES:
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 assemble tools must be of soft material and have no sharp edges. Before installation the VNISO must be oiled with system oil.
NOTES: VNISO double wiper should be used in combination of suitable rod seals to avoid hydrodynamic pressure or pressure relieving bore between seal and wiper should be constructed to prevent the build up pressures (See section; Hydraulic Sealing Elements - Sample Designs).
