What is a Buffer element?
Buffer elements such as rubber buffers absorb kinetic energy from aggregates or assemblies. They help to reduce vibrations on the overall system. The end pieces made of steel or stainless steel ensure that the rubber buffers can be installed as effectively as possible. Ideally suited for machine and aggregate construction, special machines and in transport technology.
Rubber buffers (also known as rubber bobbins / stop buffers / buffer pads) are simple and inexpensive standard elements for elastic mounting. They are suitable for compressive and shear loads. However, the loads that rubber buffers can be subjected to under shear loading is much less than that by compressive loads.
There are two main types of buffer elements, they are:
Different Rubber buffers versions are available with different Shore grades. KIPP mostly supplies them in the material combination "metal-rubber buffer" (natural rubber, steel or stainless steel). Different types are provided for certain applications. For example, rubber buffers make it possible to absorb and cushion shocks. Elements with tapered rubber contour reduce high edge loads of the rubber by radial deflection and so increase the component's service life. At KIPP, rubber buffers are available in different forms, such as rubber cylinders, rubber cones or rubber buffers with a thread. What's more, different thread sizes are available, such as M8 rubber buffers, M6 rubber buffer, conical impact buffers or door buffers.
Rubber buffers take up the kinetic energy from assemblies and so reduce vibrations in an entire system or absorb the momentum of accelerated assemblies. When constructing machines, the energy released by vibrations must not be underestimated. In most cases, these vibrations arise from rotations and oscillations. Rubber buffers are therefore frequently used when shocks or recurring movements have to be damped with an end stop. A rubber buffer significantly reduces the vibration amplitude. Classic practical applications for rubber buffers are "doorstops", "door buffers" and machine feet. The positive side-effect as a sound-absorbing element rounds off the portfolio.
