GSF-W Series Heavy-Duty Bore Glyd Ring for High-Pressure Hydraulic Systems
Filled PTFE Seal Ring + NBR/FKM/PU O-Ring Combination
The GSF-W is a premium heavy-duty bore Glyd Ring engineered for hydraulic piston sealing, combining a wear-resistant filled PTFE main ring with optional NBR, FKM, or PU O-rings to match diverse temperature, fluid, and pressure demands. It delivers exceptional dynamic and static sealing performance, with low friction and no stick-slip issues, ensuring smooth operation even in high-frequency, long/short stroke heavy-duty scenarios. Designed to tolerate large extrusion gaps and dirty media, this seal eliminates concerns about harsh working conditions, making it highly reliable for rugged applications. Its simple groove design fits integral pistons seamlessly, reducing installation complexity and saving maintenance time for hydraulic systems. Ideal for injection molding machines, construction equipment, agricultural machinery, and presses, the GSF-W enhances hydraulic system efficiency and longevity, providing long-term value for industrial operations.

Product Advantages
Exceptional Sealing Performance: The GSF-W Heavy-Duty Bore Glyd Ring, offered by Forever Seals, combines a filled PTFE main ring with an O-ring made of NBR, FKM, or PU. This design ensures outstanding dynamic and static sealing, effectively preventing fluid leakage even in high-pressure and high-frequency operation scenarios.
High Wear Resistance: The filled PTFE material of the main ring provides excellent wear resistance, extending the product's service life and reducing maintenance costs. It can withstand harsh working conditions, such as those in heavy machinery.
Low Friction and No Stick-Slip: With low friction characteristics, the GSF-W enables smooth operation of hydraulic systems. There is no stick-slip phenomenon, ensuring stable and reliable performance, especially crucial for applications requiring precise control.
Large Extrusion Gap Tolerance: It can tolerate relatively large extrusion gaps, making it suitable for applications where there may be some dimensional variations or in environments with dirty media. This adaptability enhances its reliability in rugged industrial settings.
Working Principle
The GSF-W operates based on a combined action of its components. The O-ring, available in NBR, FKM, or PU, provides the initial preload and energizes the filled PTFE main ring. When the hydraulic system is pressurized, the O-ring deforms, pushing the PTFE ring firmly against the sealing surface. The PTFE ring, with its low coefficient of friction and high wear resistance, forms a tight seal, preventing the leakage of hydraulic fluid. In bidirectional piston applications, the seal effectively seals in both directions of piston movement, adapting to the changing pressure differentials.
Product Details
Material Composition: The main sealing ring is crafted from high-quality filled PTFE, known for its chemical resistance, low friction, and excellent wear properties. The O-ring comes in options of NBR (offering good oil resistance and elasticity), FKM (with superior heat and chemical resistance), or PU (providing high abrasion resistance), allowing customers to choose based on their specific operating conditions.
Precision Manufacturing: Manufactured with precision at Forever Seals, the GSF-W meets strict quality standards. The dimensions are accurately controlled to ensure proper fit within hydraulic cylinder bores, following international standards such as ISO 7425 for groove installation. This precision manufacturing guarantees optimal performance and compatibility with various hydraulic systems.
Application Range
Industrial Machinery: Widely used in injection molding machines, where it withstands high pressures and frequent reciprocating motions, ensuring consistent and reliable operation. It is also suitable for presses, providing effective sealing in high-force applications.
Construction Equipment: In bulldozers and other construction machinery, the GSF-W copes with harsh working environments, including dirt, dust, and extreme temperatures. Its ability to handle large extrusion gaps makes it ideal for the demanding conditions of construction equipment hydraulic systems.
Agricultural Machinery: Agricultural tractors and other farm equipment benefit from the GSF-W's performance. It can operate in hydraulic systems that may encounter dirty or contaminated fluids, maintaining reliable sealing and contributing to the efficient operation of agricultural machinery.
Machine Tools: In machine tools, where precision and smooth operation are crucial, the GSF-W's low friction and excellent sealing properties ensure accurate movement of pistons, enhancing the overall performance and precision of the machine tool.
FAQ
Q: How do I choose the right O-ring material (NBR, FKM, or PU) for my application?
A: If your application involves exposure to general hydraulic oils and normal operating temperatures, NBR is a cost-effective choice. For high-temperature environments or exposure to aggressive chemicals, FKM offers better resistance. PU is recommended when high abrasion resistance is required, such as in applications with a lot of mechanical stress. Our team at Forever Seals can also provide expert advice based on your specific working conditions.
