Mackay M169 dual compression isolator without washer, 250kg

This is the Mackay Dual Compression Mobile Isolator Without Snubbing Washer.

Mackay dual compression mobile isolators are engineered to isolate vibration, control shock and reduce noise from structure-borne vibration, with high load carrying capacity, improved multi-directional resilience and built-in rebound protection. This is the M169 without snubbing washer: three part numbers in Duro 40, 50 and 60 for loads of 100 to 250kg.

These are the plain M16940, M16950 and M16960 without a washer. The M16911 snubbing washer is a separate part: Mackay supplies it with the M169 K versions only, so link to it below if you need one.

Key specifications

Choosing the right option

Choose by load: M16940 is Duro 40 at 100kg, M16950 is Duro 50 at 150kg and M16960 is Duro 60 at 250kg, all at a nominal 1.5mm deflection. Check the 16mm centre hole and the socket (34mm hole in a 16mm thick supporting member) against your mounting. Add a snubbing washer if you want the rebound shoulder. All properties are nominal.

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 partially positioned.

Insert the driving bolt, stud or assembly fixture in the metal inner member, taking care that the driving device does not overhang the outside diameter of the inner member.

Apply pressure to the driving device to seat the mounting in its socket, then assemble the other elements of the support, insert the mounting bolt and tighten to the required torque.
