Abstract: An assembly for providing support to a component, such as an ultrasonic component, including converters, boosters and horns which are subjected to continuous and repeated impacts and stresses. Such devices generally have integral nodal flanges for support purposes. In this assembly, shock-absorbing means are placed on each side of the nodal flange. A grip ring assembly is then bolted or otherwise removably fastened, together over the shock-absorbing means and nodal flange, compressing the shock-absorbing means. The component is prevented from rotating with respect to the grip ring assembly by pegs which are driven through holes provided in the grip ring assembly and into slots formed lengthwise in the nodal flange. Hence the flange itself, via the shock-absorbing means, absorbs all of the lengthwise force applied to the component by the grip ring assembly, and the pegs are required to absorb none of it.
