<P>PROBLEM TO BE SOLVED: To provide a double row bearing cage consisting of a pair of single row bearing cages each having an annular section and a plurality of pillar sections, the single row bearing cages being arranged such that their back faces abut to each other, wherein the abrasion of the back faces can be reduced, and to provide a roller bearing. <P>SOLUTION: The double row bearing cage consists of the pair of single row bearing cages 1, 1 each having: the annular section 2; and the plurality of pillar sections 3 extending in one of axial directions which are arranged side by side in a circumferential direction on the annular section 2, Here, a pocket 4 is formed among the adjacent pillar sections 3, 3 and the annular section 2 to retain a rolling element 6. An extending direction of the pillars 3 of one of the cages 1, 1 is opposite to an extending direction of the pillars 3 of the another of the cages 1, 1, and both annular sections 2 are arranged such that their back faces abut to each other. A mutually abutted interface between the annular back faces 1a of both cages 1, 1 is formed in intersection with a plane perpendicular to a center axis of the cages. <P>COPYRIGHT: (C)2012,JPO&INPIT |
