PROBLEM TO BE SOLVED: To provide a rolling bearing with a small division sensor of high reliability. SOLUTION: The bearing comprises a static track wheel 1, a rotary track wheel 6, at least one train of rotary bodies 3 allocated between the static track wheel 1 and the rotary track wheel 6, an encoder means 23 which is, attached to the rotary track wheel 6, concentric with the rotary track wheel 6, and a sensor means 14 supported with a sensor supporting block 15 while allocated facing, with a slight interval, the encoder means 23, while attached to the static track wheel 1. The travel while a bearing is rotated is detected with a sensor means 14. The sensor supporting block 15 is attached to the static track wheel 1 with a metal supporting member 16 positioned against the static track wheel 1, while the supporting member 16 is positioned on a side surface 5 extending in the radius direction of the static track wheel 1 of the bearing. |
