PROBLEM TO BE SOLVED: To dispense with a holder and a lubricant by arranging intermediate rollers at uniform intervals between inner and outer rings no contact with the inner and outer rings, pinching each outer peripheral roller with two intermediate rollers in rolling contact with the outer ring, pinching each inner peripheral roller with two intermediate rollers in rolling contact with the inner ring. SOLUTION: A required number of outer peripheral rollers 5 are arranged in the inner peripheral groove of an outer ring 3, inner peripheral rollers 6 are arranged in the outer peripheral groove of an inner ring 4, each of flanged intermediate rollers 8 is inserted into the gap surrounded by two outer peripheral rollers 5 and two inner peripheral rollers 6 at four positions, and the opposite side of the intermediate roller 8 is buried and fixed into a bored disk-like flange 9. When the inner ring 4 and intermediate rollers 8 of this bearing are rotated CW, the inner peripheral rollers 6, outer peripheral rollers 5 and outer ring 3 are rotated CCW, the sliding friction between the rollers is resolved, and all components are rotated in rolling contact with each other. No holder is required, and no lubricant is required. This bearing can be used in an artificial satellite or a vacuum device, and it is suitable for high-speed rotation.
