Operating conditions

Temperature: -100°C ...+200°C

Speed: ≤ 5 m/s

Fluids: Hydraulic fluids (mineral oil based), water emulsions

Compression strength: 20°C ≤ 12 N/mm², 100°C ≤ 7,5 N/mm²

Materials

Alloyed teflon

PO-52 = bronze reinforced, modified PTFE (PO-55)

PO-30 = carbon reinforced, modified PTFE

Advantages

- Can be delivered as cord or cut into right dimensions

- Low friction

- No slip-stick phenomenon

Calculating radial load

FR= (D x L x q / v )x n

FR= maximum radial load (N)

q = compression strength at operating temperature for the given compound (N/mm)

D x L = diameter x seal width (mm)

n = number of rings

v = confidence coefficient (recommendation > 3)

Installation

Into simple groove. Same gap (S) recommended as for Parker rod and piston seals. Gap dependent on H and operating pressure.

Cord length

Cord length: A = 3,14 x B - M

- Gap M from table

- B = guide ring’s effective diameter

- Piston B = øH - L

- Rod B = øH + L

- L = Depth of housing
