Abstract
A chuck is provided with a cylindrical workpiece gripping element having a jacket and an article gripping member and a resilient rubber-like sleeve sandwiched between. The jacket and gripping member are partially segmented into longitudinal strips so that the element as a whole can be diametrically expanded and contracted and when used to grip a workpiece having an eccentric surface the element will automatically adjust to apply equal pressure at all points on the workpiece surface and thus not distort the workpiece. The element is expanded and contracted by movable jaws.
