PROBLEM TO BE SOLVED: To provide a rolling bearing having superior durability and high reliability while preventing the breakage of pins by managing the magnitude of stress operating on the pins of a pin cage along with the acceleration/deceleration of a machine device so as to keep it under allowable fatigue stress. SOLUTION: The rolling bearing 100 comprises a roller 8 rotatably supported by fitting its through-holes 8a to the pins 2 of the pin cage 9 having the plurality of pins 2 fixed at both ends 2a, 2b to two opposed circular plates 3, 4. A ratio D/d of an inner diameter D of the through-hole 8a of the roller 8 to an outer diameter d of the pin is 1.27 or less. COPYRIGHT: (C)2004,JPO
