Abstract:
A raceway surface ( 3 a ) of an outer ring ( 3 ) of a tapered roller bearing ( 1 ) includes a composite crowning surface. The composite crowning surface includes a center curve ( 3 a 1 ), which is formed at a center portion in a generating-line direction, and end portion curves ( 3 a 2  and  3 a 3 ), which are formed on both sides of the center curve ( 3 a 1 ) in the generating-line direction. The raceway surface ( 3 a ) of the outer ring ( 3 ) is entirely subjected to superfinishing. Each of a ratio (R 2 /R 1 ) of a curvature radius (R 2 ) of the end portion curve ( 3 a 2 ) to a curvature radius (R 1 ) of the center curve ( 3 a 1 ) and a ratio (R 3 /R 1 ) of a curvature radius (R 3 ) of the end portion curve ( 3 a 3 ) to the curvature radius (R 1 ) is set to 0.02 or more. Each of drop amounts of the end portion curves ( 3 a 2  and  3 a 3 ) is set to 0.07 mm or less.

Claim (Index 10):
The tapered roller bearing according to  claim 7 , wherein the outer ring comprises a chamfered portion formed on a small-diameter-side end portion of the inner peripheral surface of the outer ring, the chamfered portion having an axial width of 0.5 mm or more.
