Abstract:
A matched ball bearing includes four or more rows of angular ball bearings axially aligned, two or more rows of the angular ball bearings with contact angles in a same direction being arranged in a back-to-back combination. The respective angular ball bearings have same inner diameters, respectively. The respective angular ball bearings with contact angles in the same direction have same outer diameters, respectively. The respective angular ball bearings with contact angles in different directions have different outer diameters, respectively. With respect to at least the respective angular ball bearings having the larger outer diameters, the angular ball bearing positioned at an axially outboard side has a ball diameter and a contact angle greater than those of the angular ball bearing positioned at an axially inboard side.
