N 75 is a single acting piston - rod seal and designed to have symmetrical lips in order to be used both for rod and piston applications..

PRODUCT ADVANTAGES:

• ​Superior static and dynamic sealing effect
• Wide range of dimensions
• Easy assembly into closed grooves
• Simple groove design
• Economical sealing solution

APPLICATION:

Pneumatic cylinders.

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 N 75 must be oiled with system oil.

Note: For special applications that require high temperatures, N 75 can be produced in FPM, also with a anti extrusion ring in ptfe white for high pressure c.a. 250 bar. The permissible gap values of N 75 pistonseal 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. 

Note: The above data are maximum values and cannot be used at the same time.

Note: It is recommended to have 50% to 90% of the working surface material contact area value.
