GN 353.1 and 353.2 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 mounts are also used as leveling feet.
The parabolic shape of these isolation mounts generates progressive resilience characteristics: Impact and shock effects are absorbed more gently.
Versions with 40 or 70 durometer natural rubber material available upon request in certain minimum quantities.
Specials, with certain minimum quantities, also available.
For metric versions see GN 353.
