J.W. Winco Inc. offers series GN 351 Vibration Isolation Mounts, Cylindrical Type in metric sizes.
The RoHS compliant components, also known as vibration mounts, anti-vibration mounts, vibration bobbins or rubber bumpers, are suitable for the elastic mounting of machine units such as motors, compressors and pumps. They are simple and economical construction elements. Their resilience and their broad range of different sizes and dimensions allow these mounts to be used in many applications that require vibration isolation.
These mounts are available in three types: with two tapped holes, with one tapped hole and one threaded stud, or with two threaded studs.
The mount body is made of natural rubber (NR), vulcanized, 55 durometer with a shore hardness of +/-5 degrees). The cover plate is made of steel, zinc plated, blue passivated, molded in, as are the tapped inserts or threaded studs. Inch size tapped and stud versions available upon request. Specials, with certain minimum quantities, are also available. 40 and 70 durometer natural rubber material available upon request.

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.
