Rubber bushings, also known as silent blocks, are molded elastomer buffer components, often bonded with metal sleeves or metal inserts. Installed between two mechanical parts, they isolate vibration, absorb shock, reduce noise, and compensate for minor displacement.
We manufacture rubber bushings in NBR, EPDM, Silicone, and FKM materials. Custom sizes, hardness, and shapes are available according to drawings or samples for automotive and industrial vibration isolation applications.
