What is the effect of an oversized groove width on the axial stability of a retained component?

If the groove width $W$ is significantly larger than the ring thickness $T$, the retained component will have excessive 'axial end play.' Under reversing loads, this leads to 'hammering,' where the component repeatedly impacts the ring. This dynamic loading can quickly fatigue the ring or deform the groove walls. For precision assemblies, the groove width should be specified as $T + 0.1mm$ maximum. If axial play must be eliminated entirely, a wave-type spiral retaining ring (which combines the functions of a ring and a wave spring) should be used to provide a constant axial preload against the retained part.
