DESCRIPTION

Manufactured by Hunger Hydraulics®, the GD1000K is a slide ring piston seal assembly used to seal and guide pistons on double-acting hydraulic cylinders.

The GD1000K consists of 6 parts; a special shaped elastic ring of a modified nitrile, a slide ring of abrasion-resistant Bronze-filled PTFE which acts as the sealing ring, two lateral support rings of modified Polyurethane, and two bearing rings made of a pressure-resistant POM-PTFE/Bronze compound.

The internal elastic ring energizes the slide ring to press it against the cylinder wall providing a sealing function at zero pressure. The onset of pressure compresses the elastic ring which increases the radial force pressing the slide ring against the cylinder wall, thereby increasing the sealing effect.

The two support rings prevent extrusion of the slide ring at high pressures. The special profile of the support rings encourages uniform fluid and pressure distribution onto the elastic inner ring. The bearing rings positioned on the support rings make contact with the cylinder walls and prevent metallic contact between the piston and the cylinder tube.
