Technical Specifications

Description &Advantages

 

The NS-34 silde 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 partculary suitable for the most vigorous applictions e.g. construction machine cylinders. The GD1000K consists of 6 parts, a special shaped elastic ring of a modified NBR, a slide ring of abrasion resistant PTFE-Bronze compound wich acts as the sealing ring, two lateral support rings of modified PUR and two bearing rings of pressure- resistant POM -PTFE-BRONZE compound. 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 pressing the slid ring against the cylinder wall, thereby increasing the sealing effect. the two support rings prevent gap extrusion of the slide ring at high pressures. The special profile of the support rings encourages uniform fluid and, pressure distribution to the elastic inner ring. The bearing rings positioned on the support rings,  make contact with the cylinder wall; there is no metallic contact between the piston and the cylinder tube.
