The invention belongs to the technical field of engineering machinery, and particularly discloses a non-contact uniform bearing of retainers and a rolling body, which is characterized in that the rolling body adopts a cylindrical rolling body or a steel ball rolling body; a through hole is formed in the rolling body, small bearing mounting holes are arranged at the two ends thereof, and a small bearing is connected with the rolling body into a whole in tolerance fit through connecting shafts and assembled in the rolling paths of an outer ring and an inner ring; two retainers are mounted on the two sides of the rolling body, retainer mounting holes are arranged in the retainer and riveted with the end parts of the connecting shafts; O rings are mounted between the connecting shafts and the retainers; gaskets are mounted between the retainers and the connecting shafts; and a cylindrical rolling body oil hole is arranged in the cylindrical rolling body. The invention has the benefits that the retainers are not in contact with the rolling body to avoid the rolling friction and the power impurities brought by the rolling friction, thereby improving the precision of the shaft and the prolonging the service life of the bearing; and as the friction of the rolling body is reduced, the heating is reduced, the lubrication is enhanced, and the bearing can rotate at a high speed.
