<P>PROBLEM TO BE SOLVED: To provide a rolling bearing which has long life, high rigidity and simple construction and is capable of being sealed. Ž<P>SOLUTION: The rolling bearing 1 includes an inner ring 2, an outer ring 3 and a plurality of cylindrical rollers 4 disposed between the inner ring 2 and the outer ring 3, and further includes a pair of O-rings 5, 5 which are disposed at both ends of bearing space S formed by the inner and outer rings 2, 3 and encapsulate the bearing space S, a pair of spacers 6, 6 which are disposed between the cylindrical rollers 4 and the pair of O-rings 5, 5, and a pair of snap rings 7, 7 which are disposed axially outwards of the pair of O-rings 5, 5. The adjacent cylindrical rollers 4, 4 are arranged side by side in the circumferential direction allowing them to get into contact with each other. The outer peripheral surface 2a of the inner ring 2 and inner peripheral surface 3a of the outer ring 3 have the same diameter. The outer peripheral surface 2a of the inner ring 2 is provided with a groove 2c into which the pair of snap rings 7, 7 are fitted. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
