Abstract
A roller assembly having a central axis can comprise a roller having an outer surface and defining an inner bore. The apparatus can further comprise a bushing comprising a sleeve having an outer surface and defining an inner bore. The inner bore of the sleeve can have an operative circumference. The sleeve comprises a bladder that is configured to expand radially upon receipt of a fluid to reduce the operative circumference of the inner bore. The bushing can further comprise a flange extending radially outwardly from the sleeve. The flange defines a vessel containing fluid therein. The vessel is in fluid communication with the bladder of the sleeve. The bushing comprises an actuator that is configured to cause the fluid from the vessel of the flange to flow into the bladder of the sleeve. An alignment feature can be configured to rotationally position the roller relative to the bushing.
