Cylindrical spacers having axially ribbed inner portions and an expanded circumference are located on the doffer shaft of a cotton harvester doffer column to support the doffers in vertically spaced relation and improve shaft strength and bend and vibration resistance. The spacer rib ends have doffer contacting surfaces to bite into the doffer and provide a keying function for enhanced doffer rotational retention.

A spacer for supporting cotton doffers in vertically offset relation on an upright spindle shaft of preselected radius, the spacer comprising: a cylindrical body having an inner wall and an outer wall, the walls having radii greater than the preselected radius of the shaft; and shaft support structure extending radially inwardly from the inner wall and terminating in shaft contacting surfaces lying generally on an imaginary cylindrical surface of radius approximately equal to the preselected radius to provide centralizing support of the spacer on the shaft.
