<P>PROBLEM TO BE SOLVED: To suppress a torque, prevent a bearing life from being shortened and balls from riding on the shoulder of a raceway, and increase a moment rigidity in a rolling bearing device supporting a cantilever rotating shaft on a fixed part. <P>SOLUTION: This rolling bearing device comprises concentrically disposed inner and outer races 2 and 3 having a radial ball bearing 1a and a slant-contacted ball bearing 1b and a ball row 6 for the radial ball bearing and a ball row 7 for the slant-contacted ball bearing rollably installed between these inner and outer races 2 and 3 parallel with each other. A ball raceway for the radial ball bearing and a ball raceway for the slant-contacted ball bearing are formed integrally with each other in at least either of the inner and outer races 2 and 3. Only a moment load by a fitted rotating shaft is substantially applied to the slant-contacted ball bearing 1b. <P>COPYRIGHT: (C)2004,JPO |
