Mackay M104 combination isolator, 125kg

Mackay M104 combination isolator is a rubber-in-shear-and-compression isolator available in four hardnesses: Duro 40, 50, 60 and 70. Combination isolators give the excellent shock-absorbing properties of rubber in shear and compression, with good dynamic cushioning under rugged operating conditions. They are designed to be used as an assembly.

The M104 measures 71mm across and 30mm high with a 16mm centre hole and weighs 0.2kg. Loads run from 57 to 180kg at 4mm deflection, rising with Duro.

Key specifications

Choosing the right option

Choose the part number by load first: each Duro has its own load and the deflection is 4mm for all of them. Match the load to the weight each isolator carries, then pick the Duro it lists. Care must be taken when installing to make sure the nut is not drawn too tightly, to avoid any excessive pre-loading of the isolator and rebound unit. The M107 is linked below if you need a different size.
