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)

barely flammable hydraulic fluids,
environmentally safe hydraulic
fluids (biological degradable oils),

others. Depending on the O-Ring

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.
