TG 508 is a piston - rod guide strip designed to be used in heavy duty hydraulic and pneumatic systems
Mobile hydraulics , excavators , mining equipment , marine hydraulics , presses and heavy duty cylinders.
Easily mounted in the housing by hand. To install the TG must be oiled with the oil system.
NOTE: We advise you to cut the strip for use in a 30 ° angle.
The length of the strip can be calculated by means of the PI of formula:
For a piston circumference minus one times the thickness e.g.
For a rod circumference plus one times the thickness e.g.
Note: The permissible sealing gap values of TG strip is indicated in the table below.
|PERMISSIBLE SEALING GAP|
|Cross-sectional thickness (mm)||Smax (mm)|
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.
MATERIAL: POLYESTER RESIN + PTFE
