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 conveyor trolleys.
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 leveling feet.
Versions with 40 or 70 durometer natural rubber material available upon request.
Specials, with certain minimum quantities, also available.
