Mackay M183 General Machinery Isolator, 35 x 29 mm, 50 to 110 kg
Available
The Mackay M183 is a general machinery isolator built as a rubber block between two flat plates, each drilled for fixing. It is listed in the Mackay Vibration Isolators catalogue with compression loads from 50 to 110 kg and shear loads from 5 to 13 kg.
It is a lower-load part than the M181 on the same catalogue page: 110 kg is the highest compression load Mackay lists for it, at 3.0 mm deflection (manufacturer-stated).
Where this product is used
- Machinery that needs mounting against the vibratory problems found within industry: Mackay says the general machinery isolators were engineered for these and are easily applied to a variety of applications (manufacturer-stated).
- Lighter machinery that suits the catalogue compression loads of 50 to 110 kg.
Features
- All angle flexibility (manufacturer-stated)
- Ease of installation (manufacturer-stated)
- Designed for stability (manufacturer-stated)
- Increased service life on equipment (manufacturer-stated)
- Ease of selection (manufacturer-stated)
- Flat plate construction, 35 mm wide and 29 mm high, with mounting holes in both plates

Selecting the right option
Pick the compression load that matches the weight each isolator carries, then check the deflection beside it: 50 kg gives 1.4 mm and 110 kg gives 3.0 mm. Check the plate lengths and hole spacings on the catalogue drawing against your supporting steelwork before fixing. If your load is higher, the M181 and M21345 are linked below. Mackay prints all properties as nominal and asks you to contact them for technical advice. Contact Mackay for critical loads.
