Configuration for a roller of a roller bearing

A method for manufacturing a tapered roller for a roller bearing, comprising:

• providing a tapered roller for a roller bearing having an end surface that terminates a rolling surface;
• and
• producing an abutment surface for a flange of a bearing ring on the tapered roller, the curvature of the abutment surface increases monotonically with an increasing of the curvature from a starting point on the abutment surface up to an inner end of the abutment surface that faces away from the raceway.

A tapered roller for a tapered roller bearing, the tapered roller bearing having a raceway and a flange, the tapered roller having a rolling surface configured to roll on the raceway and an end surface at the end of the rolling surface configured to face the flange, the end surface including an abutment surface having a curvature and a radially outer end and a radially inner end, the abutment surface being configured to contact the flange, wherein the curvature increases monotonically from a starting point on the abutment surface to the radially inner end of the abutment surface.
