Hydraulic cylinders require reliable seals to prevent leakage and maintain performance under high pressure.Glyd Ring and Step Seal designs are popular choices for piston and rod applications in the USA due to their low friction and durability.Leading manufacturers in the United States deliver high-quality options with proven materials like PTFE and advanced engineering.Here are the top three manufacturers known for excellence in Glyd Ring and equivalent Step Seal products.
1.Trelleborg Sealing Solutions
Trelleborg Sealing Solutions is a global leader with a strong presence in the USA.Turcon Glyd Ring is a double-acting O-Ring energized piston seal for dynamic applications.Turcon Glyd Ring provides low friction with no stick-slip.Turcon Glyd Ring T provides optimum leakage control and good resistance to extrusion.These seals excel in hydraulic cylinders for heavy machinery and construction equipment.
2.Parker Hannifin
Parker Hannifin is a major USA-based manufacturer of precision-engineered seals.Parker Hannifin offers a comprehensive product range to manufacturers of hydraulics equipment, based on decades of experience in sealing technology.PTFE seals are suitable for use in harsh environments with temperatures ranging from cryogenic to 300C in combination with highly aggressive media.Their step seal configurations support high-pressure applications in excavators and industrial cylinders.
3.Hallite Seals
Hallite provides high-performance equivalents widely used in the USA market.The Hallite 54 double acting piston seal provides the designer with a compact,low friction seal for light to medium duty hydraulic cylinders.Step seals buffer the primary seal from pressure spikes.Typically a PTFE based seal lip is energized against the dynamic surface using an o- ring.These designs suit mining machinery and hydraulic supports.
