<p>PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing with an aligning ring that improves a basic dynamic rating load and a basic static rating load while securing the strength of an outer ring, and can suppress the cost of a device into which the bearing is assembled.SOLUTION: A cylindrical roller bearing 1 with an aligning ring includes: an inner ring 10 that has an inner ring raceway surface 11 on its outer peripheral surface; an outer ring 20 that has an outer ring raceway surface 21 on its inner peripheral surface, and whose outer peripheral surface 22 has a spherical shape; plural cylindrical rollers 30 that are arranged in a rollable manner between the inner ring raceway surface 11 and the outer ring raceway surface 21; and an aligning ring 40 that has a spherical-shaped inner peripheral surface 41 fitted into the outer peripheral surface 22 of the outer ring 20 in an oscillatable manner. The axial width of the outer ring 20 is longer than those of the aligning ring 40 and inner ring 10.</p> |
