Piston glyd rings
The Glyd Ring has successfully used for decades as a very effective and reliable low frictional seal. These are 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 energized 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 built under the seal in reciprocating applications.
No stick-slip effect when starting for smooth operation
Minimum static and dynamic friction coefficient for minimum energy loss and operating temperature.
Suitable for non lubricating fluids depending on seal material for optimum design flexibility.
High wear resistance ensures long service life.
No adhesive effect to the mating surface during long period of inactivity or storage.
Suitable for most hydraulic fluids in relation with most modern hardware materials and surface finish depending on material selected.
Suitable for new environmentally safe hydraulic fluids.
Injection molding machines
Valves for hydraulic and pneumatic circuits
Excavators and Forklifts
