Choosing the right option
Choose the cushion by load first. Each part number has its own maximum load in compression and in shear, so work out the share of the machine weight each cushion carries and stay within the figure for the Duro you choose. All properties are nominal. These cushions have no studs, so plan the fixing before you order: stainless steel hexagonal socket set screws with a locking compound, and the C column gives the thread size. Natural rubber may not suit corrosive environments or solvents, so check with Mackay Technical staff first. Apply the load to the full face of the cushion and avoid permanent tension loading.
