ABSTRACT:
A pair of contacting rolling spheres are disposed in a tubular housing inmediate a stationary cam element and a fluidically damped and lubricated movable cam-piston member. The cam-piston member provides an axial force of sufficient strength to restrain loosely stacked elements of a spin stabilized munition. The device has its longitudinal axis offset from the main spin axis of the munition in order to utilize centrifugal forces associated with spin to generate by cam action an axial thrust force of sufficient magnitude and proper direction to restrain slidable elements within the munition.
