ABSTRACT:
A rolling bearing with seal has a stationary inner race and rotatable outer race, a first sealing ring faced to the external space and mounted to the inner peripheral end portion of the outer race which rotates during use, so that even if foreign matter in the external space such as muddy water adheres to the outside surface of the first sealing ring, it is slung off by the centrifugal force, while a second sealing ring faced to the balls and mounted to the outer peripheral end portion of the inner race, whereby it is possible to nearly completely prevent the muddy water from penetrating into the space where the rolling elements are located.
