K94 is a single acting wiper ensuring that foreign particles are not introduced into the hydraulic system.

PRODUCT ADVANTAGES
•Very good wiping performance
•Simple , easy-construction groove
•No twisting in the house
•Specially designed to prevent hydrodynamic pressure build-up
•Specially designed to provide excellent sealing against big particles , humidity and water
•Used in heavy conditions by the good mechanical properties of Polyurethane material

APPLICATION
Mining industry , heavy-duty , concrete pumps , mobile applications , telescopic cylinders.
 
MATERIAL   CODE
PU  94 SHORE A PU9401
OPERATING CONDITIONS
MEDIA Mineral oil (DIN 51524)  HFA and HFB HFC
TEMPERATURE -40°C +120°C +5°C +50°C -30°C +40°C
SPEED ≤1.0 m/sec ≤1.0 m/sec ≤1.0 m/sec
Note: It is recommended to have 50% to 90% of the working surface material contact area value. 

    

 
SURFACE ROUGHNESS Ra Rmax
Sliding Surface Ød ≤0.4 μm ≤3.2μm
Groove Base ØD ≤1.6 μm ≤10 μm
Groove Flanks  S1 ≤3.2 μm ≤16 μm

INSTALLATION
Easily installed to closed type groove. We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). It is very important that the assembly tools must be of soft material and have no sharp edges.

NOTES
Groove has to be designed with suitable form according to K94.
