Mackay M148208 Square Plate Isolator, 310 mm, Duro 60, 10,000 to 30,000 kg
Available
The Mackay M148208 is the largest part in Mackay's M1482## square plate series: a 310 x 310 mm plate isolator in Duro 60 with compression load figures of 10,000 kg at 3 mm, 20,000 kg at 6 mm and 30,000 kg at 9 mm deflection. Mackay describes its plate isolators as an uncomplicated, straightforward-design way to control vibration and shock, designed to protect equipment and machinery from damaging vibration and shock and with an excellent capacity for energy control (manufacturer-stated).
On the catalogue drawing the overall height is 120 mm, the plates are 10 mm thick and the four mounting holes are 22 mm in diameter on 270 mm spacing. The part weighs 27 kg. Mackay lists it with two smaller parts in the same series, M148213 and M148202, which carry up to 2200 kg and 7500 kg; the M148208 is the one for the heaviest loads. Mackay prints compression properties only for this series.

Figures are from the Mackay Vibration Isolators catalogue (Industrial Edition 09/2026), where the overall height (B) is 120 mm. The earlier Industrial Rubber Technology catalogue prints the same compression loads and weight but draws the height as 115 mm. Mackay prints "All properties nominal, contact Mackay for technical advice" on these tables, so treat the figures as nominal.
Selecting the right option
Match the load each mount carries to the compression table, and keep the loaded deflection within the printed 3 to 9 mm. Check the plate against your steelwork: 310 mm square plates, four holes of 22 mm diameter on 270 mm spacing, 120 mm overall height (115 mm in Mackay's earlier catalogue, so measure if the height is tight). Mackay says all properties are nominal and asks you to contact it for technical advice (manufacturer-stated). For loads near 30,000 kg, confirm with Mackay before ordering (manufacturer-stated).
