Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a bearing unit having excellent response and vibration absorbent characteristics, wherein rigidity is optimized and torque, weight and costs are reduced at the same time with increased speed and accuracy of control of an object to be borne with the bearing. SOLUTION: This bearing unit comprises a bearing assembly 10 formed by a shaft 2, a plurality of bearings 4, 6 and a spacer 8 for holding the respective bearings with a predetermined interval, and a resin bush 12 mountable to the outer periphery and having a cutout part 12a partly cut out in the shaft direction. The resin bush has a complete round inner periphery R1 and an elliptic outer periphery R2. COPYRIGHT: (C)2003,JPO
