Rolling bearing, rotating device, and method for manufacturing rolling bearing

A method for manufacturing a rolling bearing,

• the rolling bearing comprising
• an inner ring and an outer ring disposed coaxially with each other,
• a rolling body disposed between the inner ring and the outer ring,
• a sealing member mounted on the inner ring or the outer ring and covering a space between the inner ring and the outer ring from an outer side in an axial direction, and
• grease disposed between the rolling body and the sealing member,
• one bearing ring of the inner ring and the outer ring having a circumferential surface facing the other bearing ring,
• the circumferential surface being formed with a raceway surface that supports the rolling body in a rollable manner, and a recessed portion that is provided at a location extending in the axial direction from an end edge of the raceway surface in the axial direction and is recessed in a radial direction, and
• the recessed portion has a location that faces a direction inclined inward in the axial direction with respect to the radial direction;
• and
• the method for manufacturing the rolling bearing comprising:
• an application step of applying the grease by bringing the grease into contact with the recessed portion, and
• a mounting step of bringing the sealing member close to the one bearing ring to contact with the grease.

• the grease is in contact with the recessed portion, and
• the grease is in contact with a location of the recessed portion that faces a direction inclined outward in the axial direction with respect to the radial direction.
