Mackay ANB buffer, 70 x 50 x 43mm long

Mackay ANB buffer is a cylindrical rubber body bonded to a square steel baseplate, with a fixing hole at each corner of the plate. A special high-hysteresis rubber compound gives as much energy absorption as possible, uses the volume of the rubber at optimum efficiency, and effectively limits movement of equipment or machine components.

Available as three sizes: the M2255290 (70mm plate, 816 Kg-F at 21mm deflection), the M117001 (185mm plate, 5000 Kg-F at 50mm) and the M117002 (315mm plate, 40000 Kg-F at 100mm). The rubber is stiffer under dynamic conditions than under static or pseudo static loading, so more energy is absorbed for a given deformation.

Where this product is used

• Limiting movement of equipment or machine components
• Traverse cranes, using one buffer, or two buffers connected in series

Features

• Cylindrical rubber body bonded to a square steel baseplate with a fixing hole at each corner
• Special high-hysteresis rubber compound for as much energy absorption as possible
• Rubber volume used at optimum efficiency
• Low resilience of the rubber gives a high degree of energy absorption
• Simpler designs and lighter calculated forces can be considered on new machine developments, which can lower cost

Key specifications

Choosing the right option

Match the compression load and deflection to the duty, then check your fixing points against the plate side (K), hole spacing (A) and hole diameter (d) of that size. Traversing and lifting cranes appear among the typical applications. All properties are nominal.
