Abstract
A workholder with a sleeve carried by a body and providing at least in part a circumferentially continuous fluid chamber between them and at least two circumferentially spaced apart locators carried by the body axially over the sleeve and projecting radially of the sleeve. A pressurized fluid in the chamber can change the diameter of the sleeve to move the locators generally radially relative to the body into firm engagement with a workpiece so that it is carried by the workholder. The locators may be received in part in a collar received at least in part axially over the sleeve with a portion of each locator projecting radially of the collar.
