J.W. Winco Inc. offers GN 452.1 and 452.2 vibration/shock absorption mounts, cylindrical type, with stainless steel components, in inch sizes.
These RoHS-compliant 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, and can also be used as leveling feet.
GN 452.1 mounts have a threaded stud, and GN 452.2 versions have a tapped hole. The mount body is made of natural rubber (NR), vulcanized, 55 durometer (shore hardness +/-5 degrees). Cover plate is stainless steel. Tapped inserts and threaded studs are stainless steel, molded" Mount body diameters range from 1 to 2 inches.

hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
