VNI L+LI+OR (U-RING SINGLE ACTION RODSEAL)

product

VNI-L+LI+OR is a two-part, single-acting rod seal consisting of a PU sealing element, as well as o-ring and anti-extrusion ring for better sealing effect

PRODUCT ADVANTAGES

  • Excellent barrier properties and with the second sealing lip anti extrusion ring and a nbr o-ring
  • Excellent barrier properties at low pressures
  • High abrasion resistance
  • Extra lip ensures that the seal does not stick to the rod.
  • High gap bridging by anti extrusion ring

APPLICATION
Mining equipment , iron and steel industry , metal injection machines , scrap cutters , marine hydraulics , cranes and mobile hydraulics.

INSTALLATION:

Easy to assemble in a closed groove, depending on the minimum diameter values indicated in the table below. If the diameter values outside this table, we recommend an open groove. If'm assembly tools are used the mounting area should not have any sharp edges. Before mounting the VNI-L+LI+OR must be lubricated with oil system

MINUMUM DIAMETER VALUES FOR CLOSED TYPE OF GROOVES
(D-d) /2 (mm) 4 5 6 7.7 10 12.5 15
dmin (mm) 25 30 40 50 80 100 105

Note:  The permissible sealing gap values of VNI-L+LI+OR rod seal is given in the below table.

PERMISSIBLE SEALING GAP       Smax (mm)
t=(D-d)/2 150 Bar 250 Bar 400 Bar 630 Bar
  1.0 0.8 0.6 0.4

Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers. 

MATERIAL: PU 94 SH / POM / NBR
