摘要： PROBLEM TO BE SOLVED: To prevent vibration and noise from occurring by minimizing the wear of separators in a rolling bearing.
SOLUTION: In this rolling bearing having the separators 5 and 6 installed between rolling elements 3 and 3, both the separators 5 and 6 are formed of a solid lubricant, and at least one of the separators 5 and 6 is formed so that a groove-like recessed face 5d is formed in a side face part in contact with the rolling elements 3 starting at the axial one end thereof toward at least the center part thereof. By this, since the separator 5 having the groove-like recessed face 5d can be inserted for assembly into clearances between the rolling elements 3 and 3 along the axial direction without being caught even if the clearances are small, the clearances between the rolling elements 3 and the separators 5 and 6 can be reduced. Also, a contact between the rolling elements 3 and the separator 5 is brought into a line contact or a contact similar to the line contact.

摘要： PROBLEM TO BE SOLVED: To further inexpensively manufacture a rolling bearing which prevents the occurrence of dropping of a rolling body by making a split type retainer to be simply assembled. SOLUTION: The retainer is provided with a first split body 11, in which a plurality of separators 14 are integrally projected from the side face of an annular retaining ring 13 and a recessed storage part 15 for storing the rolling body 7 between each separator 14 is formed, a second split body 12 having an annular closing ring 16 with the same diameter as that of the retaining ring 13, and a connection means 17 for coaxially connecting the second split body 12 to the first split body 11. At least one of the first and second split bodies 11, 12 is formed of a material having solid lubrication properties in the retainer for the rolling bearing. The connection means 17 is composed of a latch protrusion 18 which is formed at the tip part of the separator 14 so as to prevent from coming off by being caught by the closing ring 16 by pushing the tip part of the separator 14 into the closing ring 16 side.
