Buffer, Progressive – Type C

These buffers are made with a rubber compound permitting major deformations under impact with notable absorption of energy. They can be made with high-damping rubber to order, however absorption of energy in high damped compound buffers is performed with reduced rebound movement and with slightly higher transfer levels of stress to the structure .

Product Description

Buffer progressive Type C

Rigid buffers used as end stops or to limit the stroke of moving parts give rise to high impact stresses to structures often causing visible deterioration .This is normally accompanied by unacceptably high noise levels to the human ear , particularly when these impacts are repeated periodically. Rubber buffers eliminate these drawbacks considerably, as they dampen noise and absorb energy . The simple buffer is a flat surface and therefore responds immediately to impact, without over-extending the stroke of the moving part. The progressive buffer has a conical form and therefore makes contact on a progressive basis , increasing deflection with increasing load. This action provides gradual arrest of moving parts, absorbing considerable energy, prohibiting instant high impact stresses.

These buffers are made with a rubber compound permitting major deformations under impact with notable absorption of energy. They can be made with high-damping rubber to order, however, absorption of energy in high damped compounds is performed with reduced rebound movement and with slightly higher transfer levels of stress to the structure .

Applications include: as buffers in limiting impact stress. • End of stroke of spring or damper. • End of stroke of cranes and hoists. • Supporting fragile material or machinery in packaging applications

These buffers can be used in two ways: As actual buffers – impact taking place at the end of a stroke, taking into account the maximum deflection the stop has to give. As flexible mounts where the buffers may be screwed to the base of the machine so that its flat surface rests directly on the floor or ground.
