Mackay Levelling isolator, 144mm
Available
It is an effective and durable way to isolate free-standing equipment and machinery on non-level surfaces, and it is made using Nitrile rubber, which has better chemical and oil resistance than natural rubber.
This is the standard range, made with electrolytically plated zinc applied to automotive standards. It has 5 part numbers, M400300 to M406000, with threads from M12 x 1.75 to M24 x 3.0 and load ranges that run end to end from 30kg to 6000kg. For the first three sizes a stainless steel (type 304) version is available, recommended where better corrosion resistance is required.

Choosing the right option
Share the machine weight across the number of feet and choose the size whose load range covers the load on each foot. The ranges meet at 300, 1200, 2500 and 4000kg, so where a load sits on one of those figures compare the deflection figures (given at the minimum and maximum load) and the base diameter to choose. All properties are nominal.
