グ装置。 −The main cylinder is composed of two cylinders, an inner, an outer, and a middle cylinder7, and radial bearings are provided in double rows between the two outer and middle cylinders.Furthermore, the middle cylinder and the inner cylinder are provided with axial bearings on their opposing surfaces. A plurality of annular grooves are formed with approximately half of the annular groove having a straight portion facing toward the inner cylinder, and the remaining approximately half of the annular groove is formed in the inner cylinder with at least an opening toward the inner circumferential surface side, so that both sides are formed. An endless annular ball accommodating groove is formed oriented in the axial direction of the main cylinder by joining the semicircular grooves, and the ball accommodating groove has the above-mentioned opposing groove of the inner middle cylinder on the outer peripheral surface side of the inner cylinder. The ball rolls along the inner circumferential surface of the inner cylinder, makes point contact with the outer circumferential surface of the shaft supported by the same surface, and rotates the rolling ball in both forward and reverse directions along the ball receiving groove. Bearing device that can accommodate as many as you want. −
