Claims

[Scope of utility model registration request]

(1) In a string ball bearing with a large number of balls inserted between an inner member and an outer member and without a cage, the inner member has a cylindrical surface orbit that contacts the balls, and the outer member is attached to the central axis of the bearing. It consists of two mating members divided into two on a perpendicular plane, and both mating members have a trajectory with a slightly larger curvature than the radius of the ball that contacts the ball, so that the trajectory makes angular contact with the ball. A string ball bearing characterized in that the center of the curvature is located at .

(2) The string ball bearing according to claim 1, wherein the mating member has a shoulder such that the inner opening width W formed by the mating members is slightly smaller than the diameter of the balls. .
