Slide Ring Seal for Pistons GD1000K

Product catalog summary
Overview: The GD1000K Slide Ring Seal is designed for sealing and guiding pistons in double-acting hydraulic cylinders, particularly in demanding applications such as construction machinery. It is compatible with mineral oil-based hydraulic fluids, oil-water, and water-glycol mixtures, with modified versions available for other fluids.
Specifications: The seal consists of six components: an elastic base ring made of modified NBR, a slide ring made of abrasion-resistant PTFE-Bronze compound, two lateral support rings of modified PUR, and two bearing rings of pressure-resistant POM-PTFE-Bronze compound. The elastic ring ensures the slide ring maintains contact with the cylinder wall, enhancing the sealing effect as pressure increases.
Design and Functionality: The support rings prevent extrusion of the slide ring at high pressures and ensure uniform fluid distribution. The bearing rings prevent metallic contact between the piston and cylinder, ensuring smooth operation with minimal friction. The seal is effective even at low speeds, preventing stick-slip effects and allowing precise positioning.
Materials and Application Range: The GD1000K is suitable for high fluid resistance and a wide temperature range. It is designed for pressures up to 360 bar. The seal's efficiency is optimized with a surface roughness of Ra 0.3 - 0.5 µm.
Installation Instructions: Installation involves snapping one support ring into the groove, followed by the elastic ring and slide ring. The second support ring is then inserted, and the bearing elements are snapped into place. Tools may be required for long pistons to avoid damage during fitting.
Dimensions and Ordering: The GD1000K is available in various dimensions, with further sizes and profile geometries available upon request. The document provides a detailed table for selecting the appropriate profile based on diameter and other specifications.

GD1000K Gleitring-Dichtsatz für Kolben Slide Ring Seal for Pistons Gleitring-Dichtsatz für Kolben Slide Ring Seal for Pistons Der Hunger Gleitring-Dichtsatz GD1000K wird zur Abdichtung und Führung von Kolben bei doppeltwirkenden Hydrozylindern verwendet. Aufgrund seiner Konstruktion und der speziell entwickelten Materialien eignet sich dieser Dichtsatz besonders für außergewöhnliche Beanspruchungen, z. B. in Baumaschinenzylindern. The Hunger slide ring piston seal type GD1000K is used to seal and guide pistons on double-acting hydraulic cylinders. The seal design and materials used make it particularly suitable for the most vigorous applications e.g. construction machine cylinders. Er kann bei Hydrauliköl auf Mineralölbasis, Öl-Wasser und Wasser-Glykol eingesetzt werden. Für weitere Medien stehen modifizierte Ausführungen zur Verfügung. The seal can be used in standard form with mineral oils and water base fluids. Modified versions are available for use with other fluids. Der GD1000K besteht aus 6 Teilen, einem speziell geformten elastischen Grundkörper aus modifiziertem NBR, einem Gleitring aus abriebfestem PTFE-BronzeCompound als eigentlichem Dichtring, 2 seitlichen Stützringen aus modifiziertem PUR und 2 Führungsringen aus druckfestem POM-PTFE-Bronze-Compound. The GD1000K consists of 6 parts, a special shaped elastic ring of a modified NBR, a slide ring of abrasion resistant PTFE-Bronze compound which acts as the sealing ring, two lateral support rings of modified PUR and two bearing rings of pressure-resistant POMPTFE-Bronze compound. Der elastische Grundkörper preßt infolge entsprechender Vorspannung den Gleitring auch im drucklosen Zustand an die Zylinderwand. Bei ansteigendem Druck wird der Grundkörper in axialer Richtung gestaucht, The elastic ring energises the slide ring to press it against the cylinder wall, providing a sealing function at zero working pressure. The onset of pressure compresses the elastic ring which increases the radial force 100

Dies erhöht die Dichtwirkung. pressing the slide ring against the cylinder wall, thereby increasing the sealing effect. Die beiden Stützringe schützen den Gleitring auch bei höheren Drücken vor Spaltextrusion. Ferner sorgen sie durch ihre Geometrie für eine optimale Verteilung des Mediums und damit für einen gleichmäßigen Druckaufbau am Grundkörper. The two support rings prevent gap extrusion of the slide ring at high pressures. The special profile of the support...
