ZSP
The profile ZSP is a five-piece compact seal, that is designed for both-way impingable pistons. This piston seal is a double-acting seal and guide element, which consists of an elastic profile seal ring, two back-up rings and two angle guide rings. The profile ring seals in the static and dynamic range. The back-up rings prevent an extrusion into the gap and the angle rings in the cylinder liner transmit arising shear forces.
ADVANTAGES ARE
- economic seal and guide solution
- good seal effect, also for holding cylinders
- simple snap mounting without assembly aids
- closed groove for seal element, back-up and guide rings

The values stated above keep their validity, if the processing messures incl. the tolerances will not exceed obvious under mechanical stress of the cylinders (bulging, oval shape). Range of appplication chiefly the sealing of pistons in the car hydraulics, in machine tools, pilot and support cylinders.
| MATERIAL | |
| Profile seal ring: | NBR-compound with a hardness of approx. 80 Shore A |
| Anti-extrusion rings: | Polyester-elastomer (WK035) |
| Angle guide rings: | Filled polyamide (WK016) |
MOUNTING INSTRUCTIONS
The mounting takes place in order of the several elements, incipient with one of the angle guide rings. Thereby pay attention that the joints (gaps) of the angle guide and anti-extrusion rings are ordered shifted. Sharp edges and burrs in the mounting area has to be removed.
For special cases of application (high temperatures, speed, specific pressure, use in water, HFA-, HFB-fluids etc.) please get in contact with our consultancy service.
