Description/Basics

Rubber metal elements, or also called rubber metal buffers, are generally used for oscillation and vibration damping. They are not only used to reduce structure-borne noise (transmitting vibrations), but also demonstrably reduce noise generation. This property plays an increasingly important role in the industry and mechanical engineering, as noise reduction plays an increasingly important role.

The vulcanized rubber buffers are generally fitted with mounting plates on one side or both sides. The mounting plates are provided with internal threads, external threads or through holes. Depending on the installation requirements, MISUMI offers the appropriate vibration damper.
MISUMI offers vibration-damping rubber in various materials, with different advantages and properties. Not only the respective loads and vibration frequencies must be observed when selecting rubber buffers, but depending on the application the resistance to environmental influences (e.g., oil resistance) also plays an important role. The design of the damping material also influences the damper characteristic, which can develop a degressive or progressive damping effect. It should be noted that vibration dampers do not allow complete isolation and decoupling of vibrations, but this is greatly reduced. You can find further details under the tab More information.

Rubber metal elements are often used to reduce vibration and noise in a wide variety of applications in almost all industries. Motors, pumps, and other vibration generating units are often elastically supported with vibration dampers.

Natural Rubber (NR)
Rubber metal elements made of natural rubber offer the advantage that they form a low heat development (low "heat-build-up" values) during internal creep. However, a vibrating damper made of natural rubber should not come into contact with oil, as this will cause the rubber buffer to swell and become porous, which can reduce its damping properties.

Chloroprene Rubber (CR)
Vibration dampers made of chloroprene rubber have an excellent weather resistance and good oil and ozone resistance. However, rubber buffers made of chloroprene rubber have only limited resistance to water.

Nitrile Rubber (NBR)
Rubber buffers made of nitrile rubber have the advantage of high tear resistance and abrasion resistance. In addition, rubber buffers made of nitrile rubber have good resistance to hydrocarbons, fats and oils. As a result, this material is often used for seals because it also has good temperature resistance. Furthermore, vibration dampers made of nitrile rubber are electrically conductive.

Silicone and Silicone Gel (SI)
Rubber, silicone metal bearings are very temperature-resistant, water-resistant and durable in response to the other materials. Vibration dampers made of silicone rubber also have very good chemical resistance. Silicone is a soft material that has very good damping properties, but can absorb only a small amount of supporting force.
