STRACK gas springs = robust, long-living, reliable Gas springs of STRACK NORMA particularly characterize by their robust and long-living design. Piston and piston rod consist of one piece. In addition the gas springs are partly provided with double seals and an integrated selflubrication and are thus designed for maintenance-free continuous operation. A mechanical stop guarantees a completely constant stroke. Due to the long self-centering guide bushes the gas springs of STRACK achieve an exact guidance accuracy of the piston rod. Everywhere, where in tools, devices and mechanical...

Safety features S A FET Y • Safety against too fast extending of the piston rod e.g. at sudden release of the gas spring. Safety against overstroke e.g. if due to a stroke, greater than the defined stroke of the gas spring, a compression of the body by components of the tool is caused or if the piston rod runs deeper and it will come to a collision with the bottom of the cylinder. Safety against overpressure, e.g. penetrating impurities in the gas spring can’t be compressed, they reduce the volume. STRACK NORMA GmbH & Co. KG • Tel.: +49 2351 8701- 0 • Fax: +49 2351 8701-100

Accessories Shield scraper - SN 2996 • Avoids the penetration of substances as liquid, metal particles and other impurities in the cylinder  Considerable prolongation of the service life The shield scraper is placed on the cylinder body and is retained with a lip in a groove on the body. It seals the piston rod around the cylinder tightly and avoids the penetration of impurities A cleaning lip avoids the seeping-out of excess lubricant from the interior af the gas spring This device protects the piston rods of the gas spring series SN 2808 and SN 2820 Excellent protection against liquid...

Controlled gas spring systems Controlled gas spring systems • Controlled gas spring systems with motion control can be locked in any position of the back stroke. As a result no deformation of components Compact design with working cylinder, accumulator and solenoid valve Can be controlled and used indivdually or in connection Full stroke or only a part of the stroke can be used Low spring back of maximal 0,1 mm Long lifetime Low heat development. No additional cooling required Contruction support free of charge Mounting plates for easy and quick installation of the tool and maintanance...
