PROBLEM TO BE SOLVED: To eliminate a problem found in the prior art roll bearing or slide bearing caused by rotation of a shaft member arranged at a bearing member, a rolling body supporting a load or an oil membrane of lubricant by removing the member for supporting the rotation and load of the bearing member from the bearing member and arranging it to the shaft member.SOLUTION: This invention relates to a bearing device having a quite new configuration in which some ferromagnetic granular fine particles are uniformly and magnetically adsorbed at the surface of a shaft of a magnetic shaft member and the ferromagnetic granular fine particles slide on a slide face of the bearing member, and this bearing device fundamentally resolved the problem found in the prior art roll bearing or a slide bearing. |
