ABSTRACT:
In a rolling bearing device mounted on an eccentric mounting shaft, its outer race ring is formed by pressing, and the outer cylindrical surface thereof is left as it is, not polished. Hence, an oil film is stably formed on the whole outer cylindrical surface of the outer race ring, which is a cam surface, thus preventing the cam surface from being seized or worn out. The outer race has a diameter "D" and a radial thickness "t", and the outer race has a large radial thickness which is accomplished by providing that the diameter "D" and the radial thickness "t" satisfy a formula t/D.gtoreq.0.07.
