Shear type isolators are ideal for heavy equipment such as compactors, stone crushers, generators, or excavating machinery. These isolators consist of components that effectively absorb vibrational energies through shear forces, shock impact, low frequencies, and mechanical noise.


Our specially developed rubber in the shear isolators come with the ability to absorb the heat dissipated by the vibrations. It is worth noting that the design of our shear isolators is intended for both shear and compression, despite being 'shear' vibration isolation devices.


The vintage hourglass shape helps to release the inherent tension developed during deflection on bond and rubber.


Our shear isolators are made up of two metallic components fitted with an elastomeric compound between them. This facilitates the absorption of high magnitudes of forces and ensures excellent performance.

Mackay Consolidated Industries Pty Ltd is a 100% Australian owned private company.


With nearly nine decades of rich experience, Mackay has grown to become a significant manufacturer and distributor of a diverse range of engineered rubber and rubber composite products.


Our products service the Automotive, Defence, Transport, Rail, Marine, Mining, Construction, and Industrial markets globally.

Mackay's shear-type isolators are exceptional in design and functionality, setting the bar for high-end performance characteristics in heavy equipment applications.


We set our standards through the following:


  • Equipped to absorb heat generated by the mechanical system, thereby increasing the durability

  • Equally functional in both shear and compression

  • High performance assured courtesy of the release of tensile forces from the rubber

  • Designed to provide inexpensive isolation of vibrational energies and mechanical noise

  • A perfect blend of affordability and quality

  • Decades of experience in manufacturing and supplying the highest quality of rubber products





This isolator is particularly versatile and suitable for all types of machinery and structures. The M100 is well suited to installations that require the isolator to resist the sideways pull with belt-driven loads and to maintain the centre distance

for gears, without a loss of isolation efficiency in the vertical direction.


The isolator consists of three steel members which are securely bonded to two sections of rubber in its most effective

manner, that is, in shear with progressively increasing compression.


The M100 mount is available in 50 and 60 Duro. The mounting holes can be drilled to suit your own individual requirements. The isolator can be bolted or welded to a separate retention plate if preferred, but SECURE fixing is generally recommended.


IMPORTANT: The M100 isolator should be securely fixed to the foundations before the load is applied to prevent the mount spreading and therefore, not allowing it to obtain the correct deflections.


The standard lengths are 150mm and 300mm. If you require a load rating that calls for smaller lengths it is an easy matter for you to cut to the required size.




Mackay U-Flex isolators are a general-purpose isolator which offers excellent protection against vibration and shock to a wide range of applications including electronic apparatus, vibratory feeders, general machinery as well as equipment in packing cases during transit.


U-Flex isolators are most flexible along the X and Y planes when the rubber is used in shear and offer greater stiffness along the  Z plane where the rubber is used in compression. This characteristic is particularly useful when constrained motion is required in one direction.
