Operating conditions

Pressure: ≤ 500 bar

Temperature: -30°C...+110°C (-40°C...+150°C special materials on request)

Speed: ≤ 1 m/s

Fluids: Hydraulic fluids (mineral oil based)

Materials

(1) Sealing part, Modified Thermoplastic (W5019)

(2) Expander ring, NBR-based elastomer (approx. 70 Shore A)

Installation

Housing dimensions according to ISO 7425-1.

Easy to assemble in a one-piece piston (no sharp edges allowed)

Installation chamfer (C =D-d) / 4

Tolerances

d = H9, D = H9, L = +0,2

Advantages

- Small profile

- Resistance against shock loads

- Low break-out and running friction even after long standstills and under high pressures

- Ease to assemble into a one-piece piston. No need for special tooling due split design of sealing ring

- High wear resistance

- High extrusion resistance at high pressures and large gaps due to the special compound properties of the cylinder sealing ring.

- Excellent static and dynamic sealing
