    摘要: A fluid actuated expanding mandrel or internal chuck is provided with means including very stiff springs to cause the expanding members to move outwardly a substantially equal amount, whereby a roll or workpiece is concentrically mounted, despite looseness between the bore of the roll or workpiece and the mandrel or internal chuck. A correspondingly inverted arrangement affords concentric chucking on the outer diameter of solid workpieces.
