Mackay M11440 Light Duty Flange Isolator M114, Duro 40, 40 to 60 kg

The Mackay M114 is the larger of Mackay's two light duty flange isolators: a base 92 mm long, a body 60 mm wide and a height of 29 mm, weighing 0.2 kg. Mackay says the telescopic metal inserts provide considerable stability in all directions, and that its upper metal insert is tapped to receive standard bolts or set screws (manufacturer-stated).

This listing covers three part numbers, M11440, M11450 and M11460, in Duro 40, 50 and 60, with compression load ranges of 40 to 60 kg, 60 to 85 kg and 90 to 130 kg. The upper insert thread is 1/2 inch - 20 UNF, and the base is bolted down through two 8.7 mm holes, 76.1 mm apart. Mackay lists the M114 with an optional M189 shield (manufacturer-stated).

Where this product is used

• Fastening the isolator to the floor or other base with bolts through the two lugs of the lower metal stamping (manufacturer-stated)
• Protecting the isolator from mechanical and chemical attack by fitting the optional M189 shield, which Mackay lists for the M114 and M140 (manufacturer-stated)
• Fixing standard bolts or set screws into the tapped upper metal insert (1/2 inch - 20 UNF) (manufacturer-stated)
• Mounting in the four arrangements Mackay shows as suggested methods: tandem series, compression series, tension and shear (manufacturer-stated)

Features

• Telescopic metal inserts give considerable stability in all directions (manufacturer-stated)
• Upper metal insert tapped 1/2 inch - 20 UNF to receive standard bolts or set screws (manufacturer-stated)
• Fastened down with bolts through the two lugs of the lower metal stamping (manufacturer-stated)
• Available with the M189 shield, which protects the isolator from mechanical and chemical attack (manufacturer-stated)
• Hardness colour code: Duro 40 red, 50 yellow, 60 white (manufacturer-stated)

Common specifications

Key specifications

Load and deflection ranges are the first and last rows of the Mackay load / deflection chart for each part number, which Mackay describes as approximate deflections at various static loadings. The chart gives separate figures for compression and shear. Mackay prints all properties as nominal and asks you to contact its technical department for technical advice. Dimensions are in millimetres.

Selecting the right option

Choose by load first. Each part number has its own compression load range and its own Duro, and the ranges in the chart run 40 to 60 kg (M11440), 60 to 85 kg (M11450) and 90 to 130 kg (M11460). Where two ranges meet (60 kg for M11440 and M11450) the chart prints a different deflection for each Duro at the same load, so pick the softer or firmer one by the deflection you want. Then check the base against your supporting steelwork: two 8.7 mm holes, 76.1 mm apart, 92 mm overall length, and the 1/2 inch - 20 UNF thread for the fixing into the top. Add the M189 shield if the isolator needs protection from mechanical or chemical attack. Mackay prints all properties as nominal and asks you to contact its technical department for technical advice.
