VMC Group RB Ring and Bushing Elastomeric Isolator is a ring and bushing, elastomeric shock and vibration mount designed for a variety of load ranges. The ring and bushing design provides superior wear resistance for applications where difficult shock and vibration conditions exist. These isolators are typically found in the sensitive electronic, communications equipment and weapons systems within transportable shelters as well as within the structure itself.
The RB Ring and Bushing Elastomeric Isolator provides a low profile mounting that is a failsafe restraint when used with the recommended snubbing washer. A low frequency of 10 to 12 Hz at maximum load attenuates structure-borne noise in even the most challenging applications.
The structural sections are made of carbon steel for excellent strength and durability. A corrosion-resistant coating on all metal surfaces ensures long component life. The elastomeric elements resist oils, ozone and most solvents - providing optimum resilience in nearly all environments. The operating temperature of -20⁰ to +180⁰ offers continuous operation in varying weather conditions.
