description Trelleborg Glyd Ring Overview
The Glyd Ring is a type of piston seal manufactured by Trelleborg Sealing Solutions, a Swedish industrial sealing technology company. It is a double-acting seal designed for hydraulic cylinders and actuators, typically constructed from PTFE (polytetrafluoroethylene) filled with additives for enhanced wear resistance. The low-friction properties of PTFE make the Glyd Ring suitable for applications requiring minimal stick-slip behavior and high dynamic performance. It is used in industrial equipment including hydraulic presses, construction machinery, and manufacturing systems.
help Trelleborg Glyd Ring FAQ
What is a Trelleborg Glyd Ring used for?
The Trelleborg Glyd Ring is a double-acting piston seal designed for use in hydraulic cylinders and actuators. It prevents pressurized hydraulic fluid from leaking across the piston during both the extension and retraction strokes of reciprocating motion applications.
What material is the Glyd Ring made from?
The Glyd Ring is typically constructed from PTFE (polytetrafluoroethylene) compounded with strengthening fillers such as bronze or other materials. This PTFE-based construction provides very low friction and excellent wear resistance, which are essential properties for dynamic hydraulic sealing.
How does a Glyd Ring differ from a standard O-ring seal?
While an O-ring is a simple elastomeric toroidal seal often made of rubber, the Glyd Ring is a specialized piston seal made from harder PTFE-based material specifically designed for dynamic reciprocating hydraulic applications. The Glyd Ring offers lower friction, better wear resistance, and superior performance in high-pressure hydraulic cylinders compared to standard elastomeric O-rings.
Who manufactures the Glyd Ring?
The Glyd Ring is manufactured by Trelleborg Sealing Solutions, a Swedish industrial sealing technology company that is part of the Trelleborg Group. Trelleborg Sealing Solutions produces a wide range of seals, bearings, and precision components for industries including aerospace, automotive, and industrial hydraulics.
