K32 is a two piece single acting rod seal which consists of oneelastomeric sealing element specially designed with additionalsealing lip and one thermoplastic back-up ring.

PRODUCT ADVANTAGES
• Superior sealing effect with the secondary lip
• High wear resistance
• Secondary sealing lip provides extra protection againstthe ingress of dirt particles.
• Improved sealing gap due to the active back-up ring
• Simple groove design

APPLICATION
Construction machinery , fork-lift trucks , injection mouldingmachines , agricultural machinery , mining equipment andstandard cylinders.

Groove Base ØD ≤1.6 μm ≤10 μm
Groove Flanks B ≤3.2 μm ≤16 μm
Note: It is recommended to have 50% to 90% of the working surface material contact area value.
 

INSTALLATION
Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. Before installation the sealing element must be oiled with system oil.

NOTES
The permissible sealing gap values of K32 rod seal is given in the below table.  
 
PERMISSIBLE SEALING GAP
   Pressure (Bar) Smax (mm)
150 1.0
250 0.8
400 0.6

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.
