    摘要： This rolling bearing is provided with: an outer ring and an inner ring; rolling elements arranged between the outer ring and the inner ring so as to be capable of rolling; a retainer for holding the rolling elements; and a shield. The outer ring is provided with: a raceway surface for rollably supporting the rolling elements; recessed sections formed on both sides of the raceway surface in the axial direction; and ridge sections formed between the recessed sections and the raceway surface. The recessed section is provided with: a placing surface on which grease is placed; and a first inclined section that is formed between the placing surface and the ridge section and that approaches the outer circumferential surface of the outer ring towards the outside in the axial direction.

    摘要： This ball bearing comprising a cage (4) which is made of two identical, flat, parallel rings. A metal strip starts from the ring goes down towards the center then turns 90 degrees going towards the other ring then it turns 90 degrees and meets the other ring. These metal strips, stands (5) which sit on the inner ring (7) are positioned with space between them. Above these stands there are holes where axles (3) are inserted. Round these axles there are rotating rollers (2). These rollers are smaller in radius so that they do not touch the inner ring or outer ring (6). In between these rollers there are bigger balls moving circularly that touch and hold the rotating inner ring and stationary outer ring. The balls and rollers move in harmony.

    摘要： A rolling bearing (10) comprises: an outer race (1) that includes an outer race raceway surface (1a); an inner race that is assembled with the outer race (1) and that includes an inner race raceway surface (3a) facing the outer race raceway surface (1a); and a plurality of rolling bodies (5) that are incorporated, so as to roll freely, between the outer race raceway surface (1a) and the inner race raceway surface (3a). The rolling bodies (5) are formed of stainless steel, and the surface roughness Ra of the rolling bodies (5) is no more than 0.01 µm.

    摘要： This rolling bearing has an outer race having a predetermined axis of rotation; an inner race disposed on the inner circumferential side of the outer race and in a manner concentric to the outer race; a plurality of rolling bodies disposed between the outer race and the inner race; and a strain gauge that detects strain on the outer race or the inner race. The strain gauge has three or more detection elements disposed on the outer circumferential surface of the outer race or on the inner circumferential surface of the inner race. The three or more detection elements include at least two detection elements located at positions different in the direction along the axis of rotation and in the circumferential direction of the outer race or the inner race.
