Parker R3 rod seal type

  R3-type rod seal is packing seal member with a retaining ring. Even under very harsh working conditions, this structure still has smooth motion, a good seal, anti-extrusion performance advantages. The seal ensures that the piston rod under low pressure or no pressure movement without leakage.

1. Material:

Rubber parts:

- Standard Material N3544 (nitrile rubber, hardness 88 Shore A)

- High-temperature materials V3664 (Viton, 85 Shore hardness A)

Collar:

Polon ® 062 (polytetrafluoroethylene, add 60% bronze).

2. Application:

Suitable for hydraulic cylinder rod seal.

Working pressure: ≤315 bar

Working temperature: -30 to + 100 ℃

Surface speed: ≤0.5m / s

3. Install:

An outer diameter slightly R3 interference, the outer diameter can ensure a good seal groove. After assembly, the inner diameter of the seal to

Obtaining preload to achieve the sealing function. The working life of the seal extrusion gap is mainly limited by the maximum impact.
