Description: K31 is a three piece single acting sealing set which consist of one elastomeric main sealing element with additional sealing lip , one special pro‑le elastomer nitrile rubber that goes into the main sealing component and one thermoplastic back-up ring. PRODUCT ADVANTAGES • Able to work in high pressures • Superior sealing effect in low pressures • Easy assembly into closed grooves • Superior sealing effect with the secondary lip • Secondary sealing lip provides extra protection against the ingress of dirt particles. •High wear resistance •Improved sealing gap due to the active back-up ring APPLICATION Mining equipment , iron and steel industry , metal injection machines , scrap cutters , marine hydraulics , cranes and mobile hydraulics.

SURFACE ROUGHNESS Ra Rmax Sliding Surface Ød ≤0.4 μm ≤3.2 μm 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. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil. NOTES K31 can be used in all type of cylinders safely due to the reason of perfect adaptation to the pressure changes.
