(pack) Piston-Rod Sealing U-ring K36 NBR ID 4,76mm-36mm (choose dimensions)

Description

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.

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.

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.
