Isobloc

Farrat Isoblocs have been developed specifically for, although their use is not limited too, power presses to provide effective vertical and horizontal shock absorption, vibration isolation and damping as well as easy and precise levelling on a much larger scale than Isomounts.

Farrat Isoblocs are the ideal choice for shock and vibration mitigation with high loads.

Our Isoblocs provide a simple, economical and flexible solution to factory or plant room layout planning, enabling easy installation and movement of machines without the need for bolting down or grouting.

Isoblocs are manufactured from the highest quality powder coated steel and Farrat NBR isolation materials. The design has been continuously improved to ensure long term durability against mechanical degradation and chemical corrosion. This is proven with hundreds of worldwide industrial applications.

Farrat Isobloc Selection

Select Mounts so that the below equation result is within the maximum load mount given in the table above. If the machine is made up of sections, calculate load per mount for each section:

Machine + Tooling + Workpiece Weight (Kg) / Number of Mounts

Order example (mount + screw assembly): ISB10-70 + SH30x1.5×170
