The Spiral Groove Principle

In contrast to the standard industrial impact dampener, with Zimmer’s patented spiral groove technology, the exhausting channel(throttle) is directly incorporated in the piston. By its continuous spiral groove there is a dynamic force over the total stroke and a maximum energy absorption at minimum power. A lubricating film in the form of a hydrostatic slide bearing is built up between the piston and high-pressure tube. The technological improvement is evident.

Zimmer Shock Absorber

During the dampening process the mechanical strain of the oil remains low because of the rotary spiral groove. The result is maximum energy absorption over the entire dampening stroke which guarantees a smooth dampening process.

Conventional Shock Absorber

An industrial impact dampener of conventional design squeezes oil through throttle bores which are inserted on one side of a tube. The oil is force-diverted and enormous strain is generated by the high velocities of impact creating vibrations that drastically affects the shocks lifespan
