VMC Group CM Encapsulated Elastomeric Cup Isolators are elastomeric cup isolators that provide superior shock and vibration isolation for a variety of applications, environments and mounting configurations. These isolators are ideal for use in very low load applications where portability and accessibility are required such as propulsion, guidance, radar, sonar, deck systems and other sensitive systems. 

The CM Series Cup Isolators offer a low profile, light weight, all-attitude design for flexible installation in numerous locations. The series are available in cold-rolled, zinc-plated steel or aluminum housings to meet virtually any weight requirement. All metal surfaces have a corrosion-resistant coating for extra protection and durability. Two different elastomeric element types are also available in the CM Series. The standard elastomeric element offers operating temperatures of -20⁰F to +180⁰F.
