PROBLEM TO BE SOLVED: To provide an innovative bearing exhibiting function and effect which are not conventionally available, and a grinding device.SOLUTION: The bearing includes a shaft part 2 having a receiving part 9 at the end, and a bearing part 3 for bearing the shaft part 2. A fluid is disposed in a gap S between a bearing surface 3a of the bearing part 3 and a shaft surface 2a of the shaft part 2 so that the bearing part 3 bears in a noncontact state. A rolling elements 6 are arranged between the receiving part 9 and the bearing part 3, and the rolling elements 6 are subjected to the axial load to roll and move in the relative rotation of the receiving part 9 or the bearing part 3. |
