A tapered roller bearing described in JP 7796 is known. That is, in this tapered roller bearing, a tapered roller held by a retainer is interposed between a steel inner ring and a steel outer ring,
The tapered rollers are guided by a flange formed integrally with the large end of the inner ring, and a hard carbon film (diamond-like carbon film; aka DLC) is formed on the tapered roller guide surface of the flange.
(Also referred to as a film). Since this hard carbon film does not change even under high load and high temperature conditions, it hardly causes abrasion. Therefore, the conventionally known wear on the guide surface of the collar roller is prevented.

Further, processing distortion on the inner raceway due to this surface treatment can be avoided, and bearing accuracy is not impaired. In addition, since the DLC film is formed on the abutting portion at the orbital ring divided portion including the orbital ring body and the collar, fretting does not occur on the abutting surface. As a result, it is possible to reduce the frictional force between the flange and the flange, thereby realizing low torque.
