TB is a rod-piston guide strip designed to be used in medium duty hydraulic and pneumatic systems.
PRODUCT ADVANTAGES
APPLICATION
Construction machinery , cranes , injection moulding machines , control and regulation equipment , chemical industry and standard cylinders
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 TB strip is indicated in the table below.
| PERMISSIBLE SEALING GAP | |
| Diameter (mm) | S (mm) |
| 10-25 | 0.25±0.05 |
| 26-100 | 0.30±0.05 |
| 101-300 | 0.40±0.10 |
| 301 -600 | 0.60±0.15 |
| 601-1200 | 0.80±0.20 |
| > 1200 | 0.90±0.30 |
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: PTFE (Bronze filled)
