Mackay M175001 2-Hole Hy-Deflection Dome Mount, M10, 40 kg
Available
The Mackay 2-hole Hy-Deflection dome mount is an anti-vibration mount with a domed rubber body and a flange with two mounting holes. Mackay says these Hy-Deflection dome mounts offer great elasticity in the radial and axial directions, and that their internal design suits machines that produce vibrations in 3 directions (manufacturer-stated). The design makes installation easy, and Mackay lists the dome mount as a replacement for "M" type isolators (manufacturer-stated).
Mackay says the top metal part has an internal thread for securing to the machine, and the flange has two passing screw holes for securing to the bed plate (manufacturer-stated). The three part numbers, M175001, M175003 and M175021, all have an M10 thread. Their loads are 40 kg, 75 or 70 kg (the Mackay catalogues differ) and 130 kg, with flange lengths of 114 mm, 136 mm and 150 mm.

Dimension letters follow the Mackay drawing, in millimetres: A head diameter, B height, C thread, D hole spacing, E plate size, F plate thickness and G hole diameter. The weight column is headed "KgM" in the Mackay table and is read here as kg. Figures are from the Mackay Vibration Isolators catalogue (Industrial Edition 09/2026). The older Industrial Rubber Technology catalogue prints different values for some part numbers, including a load of 70 kg for M175003 (the newer catalogue prints 75 kg). Mackay prints all properties as nominal and asks you to contact them for technical advice.
Selecting the right option
Pick the part number whose load figure matches the weight each mount will carry: the table gives one load figure, in kg, for each part number. Check the hole spacing, flange length, hole diameter and M10 thread against your machine and bed plate. For M175003 the two Mackay catalogues print different loads (75 kg and 70 kg), so confirm with Mackay if your load is close to either figure. Mackay prints all properties as nominal and asks you to contact them for technical advice. Contact Mackay for critical loads.
