An annular clamping ring for a disk pack assembly is shrink-fitted over a spindle of the disk pack. The ring has a plurality of feet annularly located on the outer portions of the bottom surface of the ring to contact the disk pack. A preload force applied to the inner portions of the upper surface of the ring creates a clamping force due to the elasticity of the ring. A thermally fit ring in Fig. 1 is indicated at 10. The ring is annular in shape and has a plurality of feet 12 spaced about the bottom of its lower surface which contact the disk pack after assembly. A cross section of one of the feet 12 is shown in Fig. 2. When fitting the ring to a disk pack, the ring is heated to a point where its inner diameter is greater than the diameter of the hub of the disk pack.
