Abstract
An improved tapered roller bearing in which a shoulder at a small diameter end side of an inner race has been eliminated. A shoulder portion for maintaining a state of engagement between an inner race and a cage for holding tapered rollers at circumferentially equally spaced positions after assembling, is formed at an outer peripheral portion of a large diameter side of the inner race. Furthermore, projections for engagement with the shoulder portion are formed in positions not hindering the assembling of the tapered rollers at the large diameter side of the cage.
