Parable buffer

Parabolic buffer for impact damping and limiting vibration amplitudes.

The parabolic buffers in our product range are designed for progressive shock absorption in structures with stoppers. They are used in conjunction with spring bearings to limit vibration amplitudes. The parabolic rubber buffers are also used as machine feet when progressive reduction of vibrations/impacts is desired. Visit our online shop for more information. Please call us or send us a request for custom dimensions!

Frequently asked questions (FAQ)

Progressive shock absorption means that the buffer/spring becomes harder and harder as the load increases, as a result the buffer/spring is prevented from breaking down under heavy loads and ensures that vibrations subside quickly. In contrast to this is the degressive damping which becomes softer with increasing load.
As there is no fixed connection, no metallic contact between the components, the transmission of mechanical or acoustic vibrations is reduced or even eliminated.
Vibration isolation or vibration reduction can be achieved by elastic and damping elements to reduce the forces from a machine or the vibrations transmitted from the environment to a machine, if certain forces are applied to a machine or device and these are supported on elastic and damping elements thereby reducing the transmission of these forces to the environment. This type of vibration insulation is called source insulation and active vibration insulation. If a building or a machine is supported on elastic and damping elements in order to reduce the ground displacements which act as foot point excitation from the system to be protected, this type of vibration insulation is called receiver insulation of a passive vibration insulation.
Moving parts on machines, equipment, apparatus and vehicles generate vibrations and noise. They are caused by uneven or rotating movements of unbalanced masses. Vibrations and shocks act as vibrations and noise disturb the environment.
Impact insulation reduces the impact-like forces that arise as a result of impact excitation.
Vibrations and structure-borne noise are vibrations and can be positively influenced by applying the following basic principles of vibration reduction or by design measures. Vibration insulation, structure-borne sound insulation and impact insulation design measures
