K36 PISTON - ROD SEAL 20X28X6.3 NBR

K36 is a single acting piston - rod seal which consists of reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element.

PRODUCT ADVANTAGES
• Functions even with poor surfaces
• Reinforced cotton fabric base prevents the seal from extrusion
• Both rod and piston application
• Good sealing at low pressures

APPLICATION
Low to medium duty hydraulic cylinders , mobile hydraulics and presses.

SURFACE ROUGHNESS	Ra	Rmax
Sliding Surface ØD-Ød	≤0.4 μm	≤3.2 μm
Groove Base Ødp - ØDb	≤1.8 μm	≤6.3 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 K36 is to be assembled into open grooves. 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 The permissible sealing gap values of K36 piston - rod seal is given in the below table.

PERMISSIBLE SEALING GAP

Pressure(Bar)	S (mm)
150	0.2
250	0.1

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.
