A rotating breech lock rotates tubing to distribute wear caused by a rotating or reciprocating rod of an artificial lift system. The rotating breech lock has a spool that disposes on a wellhead. A bowl element disposes in the spool's bore, and a hanger fits into the spool and lands on the bowl element with a thrust bearing. Above the hanger, a load ring fits against the hanger with a bearing, and a hold-down sleeve and locking pins hold the load ring against the hanger. The spool has a worm that mates with a wheel defined about the hanger so turning the worm by a ratchet or other mechanism rotates the hanger. Internally, the hanger has a bore with opposing shoulders separated by gaps. A mandrel couples to the tubing and disposes up into the hanger. Protrusions or keys on the hanger can selectively align with the gaps and the shoulders depending on how the mandrel is rotated in the hanger bore.
