    摘要: An end faced on an outer side in a radial direction of a small diameter annular portion of a retainer is disposed on an inner side in a radial direction of a pitch conical face of a taper roller and an end face on an inner side in a radial direction of a large diameter annular portion is disposed on an outer side in the radial direction of the pitch conical face. Further, a portion of the small diameter annular portion opposed to a small diameter end face of the taper roller is disposed on the inner side in the radial direction of the pitch conical face and a portion of the large diameter annular portion opposed to a large diameter end face of the taper roller is disposed on the outer side in the radial direction of the pitch conical face.

    摘要: A tapered roller bearing according to the invention is such that when an arithmetical mean roughness as a surface roughness of a large end face of a tapered roller is σ1 and an arithmetical mean roughness as a surface roughness of a large rib surface of an inner ring is σ2, σ1 is 0.04 μm or larger, and a composite roughness that is expressed by a square root of a sum of a squared value of σ1 and a squared value of σ2 is 0.17 μm or smaller. Raceway surfaces of an outer ring and the inner ring and a rolling contact surface of the tapered roller are crowned, and a total crowning amount is set to 50 μm or larger, an outer ring crowning rate is set to 40% or larger, and a roller crowning rate is set to 20% or smaller.
