GN 353 Vibration / Shock Absorption Mounts Conical Type, with Steel Components


Product description


GN 353 vibration / shock absorption mounts, also known as shock absorbing mounts, vibration mounts, anti-vibration mounts, vibration bobbins or rubber bumpers, are frequently used as end-stop bumpers, e.g. for conveyors.

They absorb most of the accumulated kinetic energy on impact. They act as dampers and prevent damaging shock and rebound. They also act as sound dampers. These isolation mounts are also used as set-up elements and leveling feet.

The parabolic shape of these isolation mounts generates progressive resilience characteristics: Impact and shock effects are absorbed more gently.

For inch versions see GN 353.1 / GN 353.2.
