Rubber bobbins are found usually in areas that require vibration damping. They are shock absorbers and usually found as feet, supporting a motor or pump / exhaust system. Anything that potentially could vibrate.
Bobbins are invariably made of Natural rubber as this has good elastic properties, but we are able to tailor the rubber material to suit the application. If oils are present then we would consider other materials resistant to the specific conditions.
Our engineering department will also manufacture the metals that sandwich between the rubber.
