Product Description

PTFE Bronze Compact Seal Style GSF Glyd Rings Piston rings
Successfully used for decades, the Glyd Ring is a very effective and reliable low frictional seal. It is particularly suitable as a rod seal in both high and low pressure systems.
The double acting Glyd Ring is a combination of a based slipper seal and an energising O-Ring. It is produced with an interference fit which together with the squeeze of the O-Ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-Ring is energised by the fluid, pushing the Glyd Ring against the sealing face with increased force.
The geometry of the Glyd Ring ensures a good static sealing and allows the lubricating hydrodynamic oil film to be build under the seal in reciprocating applications.

To assure that a rapid energising of the seal takes place at sudden changes of pressure and direction of motion, the seal can be delivered with radial "notches" on both sides.    

Operating conditions

The Glyd Ring is recommended for reciprocating (with a length of stroke at least twice the groove width) and helical movements.
Pressure: Up to 60MPa
Speed: Up to 15 m/s
Frequency: Up to 5 Hz.
Temperature: -45 °C to +200 °C
(depending on O-Ring Material)

Media

Mineral oil based hydraulic fluids,
barely flammable hydraulic fluids,
environmentally safe hydraulic
fluids (biological degradable oils),
phosphate ester, water, air and
others. Depending on the O-Ring
material compatibility.


Important Note

The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed

depends on material type, pressure, temperature and gap value.
Temperature range also dependent on medium.

Materials

All round material for hydraulic applications with reciprocating, short stroke or helical movements in mineral oils, flame retardant hydraulic fluids HFC, phosphate ester, bio-oils or fluids having less satisfactory lubricating properties:
O-Ring: NBR, 70 Shore A N FKM, 70 Shore A V
Set code: M12N or M12V
For medium to heavy applications with reciprocating
movements in mineral oils and other media with good
Lubrication

Advantages of Glyd Ring

- No stick-slip effect when starting for smooth operation.
- Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature.
- High wear resistance ensures long service life.
- No adhesive effect to the mating surface during long  period of inactivity or storage.
- Suitable for new environmentally safe hydraulic fluids.
- Available for all rod diameters up to 2,600 mm.
