Answer
In high-volume production (e.g., transmission hubs), pneumatic plungers are used. The rings are stacked in a magazine and fed onto a plunger. The plunger pushes the ring through a 'tapered sleeve' that compresses (for internal) or expands (for external) the ring. Once the ring reaches the groove, it snaps into place. The critical parameter is the 'Stroke Limit' and 'Force Monitoring'; if the sleeve is misaligned, the ring can be 'shaved' (material removed) or 'tangled'. Sensors detect the 'snap' via an acoustic or force-drop signature to verify successful installation.
