We have found them to be generally as effective or better, being more adaptable to a broader range of applications. Hard cones and bearings are effective at reducing vibrations in the horizontal and oblique planes; they often transmit, rather than diminish , vibrations in the vertical plane, however. These types of devices are best used to “couple” a component to a vibration-free surface. Square footing, by contrast, absorbs vibrations in all planes; they work great between a component and just about any kind of surface. They isolate components internally and externally. They work well in conjunction with rigid isolation devices, too. For example, you might have cones between your platform and floor — using Square Footing between the platform and component will make effective use of both theories of isolation.
