Mackay Dual compression mobile isolator

Its dual compression mobile isolators are engineered to isolate vibration, control shock and reduce noise due to structure borne vibrations, with high load carrying capacity, improved multi-directional resilience and built-in rebound protection. Available as 14 part numbers across six body sizes, in Duro 40 to 75, with load ranges from 8 to 35kg at the light end to 250 to 1000kg at the heavy end.

The ten M539 part numbers each have a load range and a nominal deflection of 0.7, 1.2, 2 or 3mm. The M169 isolators, in Duro 40, 50 and 60, are available separately with and without the snubbing washer.

Key specifications

Choosing the right option

Then check the dimensions for its generic number against your socket (the socket hole diameter G and the thickness of the supporting member H). Use the washer arrangement for the rebound shoulder, and see the with-washer and without-washer M169 versions linked below. All properties are nominal.

The fitting steps are: lubricate both the isolator and the socket with water; insert the part in the socket and rotate it by hand while applying axial force until it is partly seated, driving through the metal inner member with a bolt, stud or assembly fixture that does not overhang the outside diameter of the inner member, so the elastomer is not damaged; apply pressure to seat the mounting in its socket; then assemble the other support elements, insert the mounting bolt and tighten it. When the nut is tightened against the snubbing washer the rebound shoulder forms automatically, and the resulting pre-compression will ensure optimum performance.
