Glyd Ring
O.D. Sealing
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.
Advantages of Glyd Rings:
-
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.
Applications:
-
Injection molding machines
-
Machine tools
-
Presses
-
Handling machinery
-
Valves for hydraulic and pneumatic circuits
-
Excavators and Forklifts
-
Agriculture equipment
Material: Bronze (T46)
Used as a standard material for hydraulics, it offers high compressive strength, good sliding and wear properties, and good extrusion resistance. Typically a greyish to dark brown color.
