Temperature: -30 °C ... +110 °C (-40 °C ... +150 °C special material, by request)
Speed: ≤1 m/s
Liquids: Mineral oil-based hydraulic fluids
Materials
1. Seal part: filled modified thermoplastic (W5019)
2. Rubber ring: nitrile rubber, hardness 70 Shore A
Installation
Seal groove dimensioning according to ISO 7425-1
Easy to mount for a one-part piston that cannot have any sharp edges.
Mounting chamfer (C =D-d) / 4
Tolerances
d = H9, D = H9, W = +0.2
Advantages
- Small profile
- Good resistance to pressure impact
- Low start-up friction and motion friction, even after long idleness at high pressure
- Easy to install in a one-part piston. No special tools are required, as the seal ring is split.
- Good resistance to wear
- Low risk of penetration into clearances at high pressures; allows large clearances due to the material of the seal ring.
- Excellent dynamic and static tightness.
