Failsafe Shear Cap Vibration Isolator (150 - 1,300 Kg)

What is a Failsafe Shear Cap Vibration Isolator, or Bell Mount?

The Failsafe Shear Cap Vibration Isolator is a bell-shaped anti-vibration mount.  It is a popular option for rubber/metal anti-vibration pedestal mounts when used with compression loads.  Should there be an issue which compromises the rubber's ability to do its job, the component is held together with a failsafe mechanism.

It provides a low-profile solution for isolation problems of numerous machines with rotation speeds of over 1500 revolutions per minute (compressors, motors, fans and pumps).

The elastomeric component is partially protected by the galvanised steel shell.

This isolator offers a good balance between isolation performance, mount height, and price.

This mount is designed to be used when mounted to a flat horizontal surface.  The load applied then acts vertically downwards towards the ground.

One notable advantage of all Shear Cap, or Bell Mounts, is that their properties tend to be more uniform with small changes in direction of load.  E.g. if used on a ship, the rocking of the ship will have a reduced impact on isolation when compared to standard Pedestal mounts.
