Back-up rings do not have a sealing function. They are designed to prevent elastic sealing elements such as O-Rings or Quad Rings of gap extrusion.
Features
Application
Installation
Back-up rings do not have a sealing function. They are designed to prevent elastic sealing elements such as O-Rings or Quad Rings of gap extrusion.
Features
- Normally cut at an angle for easy installation, but also available as non-split version.
- Low dynamic friction.
- Low break-away forces after long standstills.
- Activated back-up rings reduce gap extrusion and prevent twisting of the seal in the groove.
Application
- Dynamic and static applications in reciprocating pistons and rods in hydraulic cylinders,
- plungers, etc.
- Unfavourable tolerances and wide gap dimensions.
- Intensely pulsating pressures and pressure change.
Installation
- Snap-in installation; split or unsplit
