In a stringed musical instrument machine head, a string post is supported by a housing for rotation about its longitudinal axis and has an upper portion extending from the housing for attachment to a string and a lower portion carrying a worm wheel. A relatively long intermediate bearing portion of the post passes through an equally long bearing opening in the housing to reduce the ability of the post to wobble or shift relative to the housing, and further restraint against such unwanted movement of the post relative to the housing is provided by having the housing include a sleeve portion defining the lower part of the bearing opening and received in a recess in the worm wheel, with the worm wheel and sleeve portion of the housing also having co-engaging bearing surfaces.
