JW Winco 452-30-25-M8-S-55 Series GN 452 Rubber Type S Cylindrical Vibration and Shock Absorption Mount with Threaded Stud, Metric Size, 30mm Diameter, 25mm Height

GN 452 vibration / shock absorption mounts, also known as vibration isolation mounts, anti-vibration mounts, vibration bobbins or rubber bumpers, are 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.
