GN 253 Vibration / Shock Absorption Mounts Conical Type, with Steel Components, Tapped Hole


Product description


GN 253 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.
