<p><P>PROBLEM TO BE SOLVED: To provide a structure capable of increasing the total number of pockets 5, 6 as much as possible in a ball-cage 1 for a combined roller bearing obtained by combining two halved ball-cages 2, 3. <P>SOLUTION: A circumferential length in the first halved ball-cage 2 is determined to be longer than that of the second halved ball-cage 3 under a condition that the cylindrical shape is formed when the first halved ball-cage 2 and the second halved ball-cage 3 are combined, and the number of pockets 5 of the first halved ball-cage 2 is more than the number of pockets 6 of the second halved ball-cage 3 by one. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
