Description:

Turcon® Glyd Ring® is a double-acting O-Ring energized rod seal for dynamic applications. It provides low friction with no stickslip, minimal break out force and high wear resistance. Installed in grooves to ISO 7425.

Turcon®Glyd Ring®is a very effective and reliable low friction 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 Turcon®based slipper seal and an energizing O-Ring. It has 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 energized by the fluid, pushing

Glyd Ring®against the sealing face with increased force.

The geometry of Glyd Ring®ensures good static sealing and allows the lubricating hydrodynamic fluid film to be built under the seal in linear applications.

OPERATING CONDITIONS: 

Glyd Ring®is recommended for linear (with a length of stroke at least twice the groove width) and helical movements.

Pressure: Up to 60 MPa

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, flame retardant hydraulic fluids, environmentally

friendly hydraulic fluids (bio-oils), phosphate ester, water, air and others, depending on the seal and O-Ring material compatibility, see Table 64.

Clearance: The maximum permissible radial clearance Smax is shown in Table 65, as a function

of the operating pressure and functional diameter

ADVANTAGeS:

- No stick-slip effect when starting for smooth operation

- Minimum static and dynamic friction for a minimum energy  loss and operating temperature
