VNISO COMBY WIPER FOR ROD HYDRAULIC K 107

product

VNISO/K  is a double acting rod seal and rod scraper with extra outside lip combination specially designed not to require additional element for axial fitting within the housing.

PRODUCT ADVANTAGES:

  • Good wiping effect
  • Wide range of dimensions
  • No twisting in the housing
  • Wiper lip reliably wipes away dirt and leaves a residual oil film on the retracting rod.
  • Double lip makes additional protection to prevent the particles to enter into the cylinder
  • Easy installation

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/l must be oiled with system oil.

NOTES: VNISO/l 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).
