Mackay MA5921455 Impact Buffer Vibration Isolator, 1300 kg Static, 6000 kg Buffing

The Mackay MA5921455 and MA5921055 are the larger impact buffers in Mackay's Vibration Isolators catalogue. Mackay's drawing shows a rubber block on a flat rectangular plate with four mounting holes. Each part is rated by a static load and a buffing load, with a deflection for each (manufacturer-stated).

This listing has two variants. The MA5921455 has a static load of 1300 kg and a buffing load of 6000 kg on a 250 x 120 mm plate; the MA5921055 has a static load of 2250 kg and a buffing load of 10000 kg on a 300 x 150 mm plate. Mackay prints a third part in the same table, the MA5924455 (700 kg static, 3600 kg buffing), which is not part of this listing.

Common specifications

Key specifications

Letters A to J follow Mackay's drawing: A is the height, B and C are the plate length and width, D is the hole diameter, H is the hole spacing at one end of the plate and J is the plate thickness. Static load and buffing load are Mackay's column names.

Selecting the right option

Work out which rating matches your duty, static load or buffing load, then pick the part whose rating covers it. Check the plate (B x C), hole diameter (D) and hole spacing (H) against your fixing points. The catalogue gives no application notes for these parts. Mackay prints all properties as nominal and asks you to contact them for technical advice.
