Mackay Recessed flange isolator, duro 45

Mackay 172 x 150 x 100mm recessed flange isolator is available in four Duro grades under base number M801550. Mackay makes its recessed flange isolators for high load capacity with relatively large static deflections in the axial direction, and says the rubber is used in both compression and shear to give a high loading for the size.

The four part numbers (M80155045, M80155050, M80155060 and M80155070, Duro 45, 50, 60 and 70) each carry two figures in the Max Load column: 400 to 1200kg at 7mm displacement and 640 to 1860kg at 11mm displacement. The plate is 172 x 150mm with four ø11mm holes, the centre bolt is M24 torqued to 260Nm, and each isolator weighs 4.5kg. The overload and rebound washers are ordered separately, with M181550C for both positions.

Where this product is used

• Supporting equipment that needs high load capacity with relatively large static deflections in an axial direction
• Installations where overload and rebound washers control and limit the movement of the suspended equipment under shock loads

Features

• Rubber is used in both compression and shear, which gives high loading for the size
• Four Duro grades (45, 50, 60 and 70), each with two Max Load figures at 7mm and 11mm displacement
• Parts are colour coded by Duro and also stamped with their Duro
• Overload and rebound washers (M181550C) are ordered separately
• M24 centre bolt with a recommended assembly torque of 260Nm

Key specifications

Choosing the right option

Choose the Duro by load first. Each part number has a Max Load at 7mm displacement and a higher Max Load at 11mm displacement, so compare the load each mount carries with the figure at the displacement you are designing for. Check the base plate against your steelwork: 172 x 150mm, with four ø11mm holes on 144 x 100mm centres. Order the M181550C overload and rebound washers separately (linked below) and torque the M24 centre bolt to 260Nm. All properties are nominal.
