Mackay Low-frequency isolator, 50 - 350kg

Mackay Hy-Deflection isolator is a lattice-style rubber isolator that gives flexible support to mechanical equipment subject to intermittent or continuous, low frequency, high amplitude vibration. It comes in three part numbers, M18840, M18860 and M18875, with compression loads from 50 up to 1400kg and deflections up to 28mm.

The design gives a soft spring rate in all directions with exceptional horizontal stability, and suits applications where the disturbing or forced frequency is as low as 5 hertz. It is not suitable for applications involving repetitive shock load. Each isolator weighs 10.0kg.

Where this product is used

• Vibrating screens and vibrating conveyors
• Generators, industrial refrigeration units, air conditioning compressors and industrial pumping equipment
• Shipboard applications, and equipment where a high degree of vibration isolation is required

Features

• Lattice design gives a soft vertical spring rate combined with lateral stability
• Recommended where the disturbing or forced frequency is as low as 5 hertz
• Intended for applications where high static deflection is required, not suitable for repetitive shock load
• Overall length (base): 305mm

Key specifications

Choosing the right option

Choose the part number by load first: M18840 covers 50 to 350kg in compression, M18860 100 to 800kg and M18875 100 to 1400kg. It is not suitable for repetitive shock load. Check the 276mm base hole spacing, 19mm holes and 5/8 UNF top thread against your equipment. All properties are nominal.
