Bearings & Power Transmission > Anti-Vibration Mounts | Mackay Annular Isolator | Mackay Annular Isolator | Replaces Hy-Deflection Low-Frequency Isolators | Anti-vibration isolators provide large deflections under small loads. | Protects instruments and apparatus from transmitted vibration and shock as well as vibration from light machines and equipment. | Normally fitted to take loads in compression or shear. | Continuous loading in tension is not recommended although the occasional shock load which places the rubber in tension can be permitted. In compression, shock loads severe enough to close the centre hole can be taken with safety. | Low-frequency instrument isolators are available in two sizes, each with a range of Duros available in each size.
