X-Ring XR
Description
- Endless, circular ring with x-shaped cross-section
- Advantages
- Downloads
- Function
- Applications
- Optimized sealing effect (good pressure distribution over square cross-section)
- Low friction due to lower contact forces
- ulbricant depot possible between the sealing lips
- High stability in dynamic applications due to almost square cross-section
- Lower radial preload required
- No interference by separation rate
- Sealing effect due to cross-sectional deformation after installation and axial or radial compression in the installation space
- In the operating state, media pressure reinforces the sealing function
Most commonly used in the following applications:
- Dynamic sealing for reciprocal, rotating and superimposed screw movements
- Static sealing of stationary machine and system parts against liquid and gaseous media (flange and cover seals, pipe fittings, cylinder head and base for hydraulic cylinders)
- Comparable in handling and application to O-rings
- Sealing of pressures up to 1000 bar, use of back-up rings may be necessary
