<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device for supporting a wheel reduced in rotating torque, enabling the secure removal of static electricity, making hard the leakage of grease and the entry of foreign matter, and usable for a long period. <P>SOLUTION: This rolling bearing device for supporting the wheel comprises an outer member 1, an inner member 3 formed of a hub 4 and an inner ring 5, and two rows of rolling elements 10 and 10. Also, seal devices 12a and 12b are installed between the inner end side inner peripheral surface of the outer member 1 and the inner end side outer peripheral surface of the inner ring 5 and between the outer end side inner peripheral surface of the outer member 1 and the intermediate part outer peripheral surface of the hub 4. The conductive grease is filled in a clearance surrounded by the elastic member 107 and the slinger 106 of the seal device 12a and a clearance surrounded by the elastic member 217 and the hub 4 of the seal device 12b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
