ABSTRACT:
An expandable airlock shaft with surface mounted roller bearings provides differential core speed slipping capability for adjacent core segments on a common shaft. The shaft may be used with an expandable collet system consisting of a set of relatively short, expandable collets, which are used with spacers where needed to accommodate multiple core segments in any desired arrangement. Alternatively, the roller bearings may be incorporated into the expandable collets, and the shaft configured with an expandable bearing support surface.
