Mackay Recessed flange isolator

Mackay Type 31 is a recessed flange isolator for equipment that needs high load capacity together with relatively large static deflections in the axial direction. It gets its high loading for its size by using the rubber in both compression and shear.

Available as three part numbers, M137063, M137061 and M137062, in Duro 50, 60 and 70. Loads run from 310 to 960kg with 6.0 to 6.5mm deflection, and each weighs 1.18kg. The flange is a four-hole plate 91 x 106mm with ø10.2mm holes, and the isolator is 66mm high. It is supplied with overload and rebound washers.

Where this product is used

Features

• Rubber is used in both compression and shear, which gives high loading for the size
• Supplied with overload and rebound washers

Key specifications

Choosing the right option

Choose by load first: each part number has its own load figure and Duro, so work out the share of the machine weight each mount carries and pick the figure that matches. Then check the plate against your steelwork: four ø10.2mm holes on a 70 x 82.5mm pattern, plate 91 x 106mm. The central fixing bolt should be torque tightened to its recommended value. All properties are nominal. If your load is outside 310 to 960kg, the larger Mackay recessed flange isolators are linked below.
