Abstract
A rotary spindle has a rotatable shaft that defines a shaft axis of rotation, and has a shaft top land that is normal to the shaft axis of rotation. A disk mounting hub has an outer disk mounting surface, and has an inner cylindrical bore with an inner cylindrical surface that faces and is in radial compression with an outer cylindrical surface of the shaft at a cylindrical hub-to-shaft interface. The cylindrical hub-to-shaft interface is substantially concentric about the shaft axis of rotation. A disk clamp is fastened to the rotatable shaft, and the disk clamp has a clamp bottom land that faces and is in contact with the shaft top land.
