QUIDE STRIP PO-55- 12,8 X 3

Conditions of use
Temperature: -100 °C ... +200 °C
Speed: ≤15 m/s
Liquids: mineral oil-based hydraulic fluids, water emulsions
Compressive strength for material: 20 °C ≤ 12 N/mm², 100 °C ≤ 7.5 N/mm²
Materials
Filled PTFE
PO-52 = bronze-reinforced modified PTFE (PO-55)
PO-30 = carbon-reinforced modified PTFE.
Advantages
- Supplied as ribbon or pre-cut
- Low friction
- No stick-slip phenomenon
Calculation of radial load
FR = (D x L x q / v) x n
FR= maximum radial load (N)
q = maximum allowed radial load for the material (N/mm²)
D x W = diameter x width mm²
n = number of rings
v = safety factor (recommendation > 3)
Installation
Mounted in a single groove.
It is recommended to use the same clearance S as with Parker shaft and piston seals.
The gap depends on H and the operating pressure.
Tape length
Tape length A = x B - M
- Gap M from the table
- B = average diameter of the guide ring
- for the piston B = øH - L
- for the shaft B = øH + L
- L = groove depth
