Mackay V-shaped isolator for small engines, 90kg

Mackay single shear V-shaped isolator is made of two symmetrically tilted metal parts with a screw on each side. This makes installations more elastic than with cylindrical or bobbin mounts, giving a lower frequency and better vibration isolation.

Four variants: two sizes (weights 0.1 and 0.2kg) in Duro 45 and Duro 60, with loads of 5 to 90kg and 5 to 9mm static deflection. They provide vibration attenuation of above 90% in diesel or petrol single-cylinder engines running at 3000rpm.

Where this product is used

• Very low-load engines requiring high levels of isolation
• Portable gen sets, compressors and motor pumps

Features

• Two different length screws make it easier to assemble the engine to the chassis
• Two anti-turn tabs stop the mount turning when strong tightening torque is applied, very frequently with pneumatic tools
• Stability is enhanced when two are installed, symmetrically opposed
• Supplied in two hardnesses (Duro 45 and 60) to suit different load ranges
• Vibration attenuation of above 90% in diesel or petrol single-cylinder engines running at 3000rpm

Key specifications

Choosing the right option

Choose the size first, then the Duro: the smaller parts (M148151 and M148153) carry 5 and 15kg, the larger parts (M148171 and M148173) carry 43 and 90kg. Stability is better when two are installed symmetrically opposed, so work out the load each one carries. All properties are nominal.
