摘要： PROBLEM TO BE SOLVED: To secure the smooth operation of a rolling bearing and prevent noise from occurring against the displacement of the position of the split face of the split type housing of a crankcase and others due to assembling errors.
SOLUTION: The outer ring 11 of the rolling bearing is circumferentially divided into two parts at the split face 11a (vertically into two parts in the figure). Wall thickness reduced parts 20, 21 smaller in wall thickness t than the other portions are formed at both end parts of each of the outer rings 11b, 11c so that the wall thickness t can be smoothly changed along the circumferential direction (wall thickness t1 → t2). The wall thickness reduced part 20 of one outer ring 11b of the outer ring 11 and the wall thickness reduced part 21 of the other outer ring 11c of the outer ring 11 are fitted to each other through the split face 11a of the outer ring 11 and connected to each other through the split face 11a. In this state, the wall thickness reduced parts 20 and 21 continued with each other form a circular arc shape having a radius of curvature smaller than that of each of the outer rings 11b and 11c. The lengths of the wall thickness reduced parts 20 and 21 continued with each other along the circumferential direction is less than the arrangement distance of rollers 12 along the circumferential direction.

摘要： PROBLEM TO BE SOLVED: To provide a compact bearing having a long service life, and receiving a radial load, a bidirectional axial load and a moment load under a service condition of being large in a difference in the load size received in the both shaft directions.
SOLUTION: A plurality of rolling bodies 5 and 5' are incorporated between an outer race 1 and an inner race 2 having respectively two raceway surfaces. The outer-inner races have the raceway surfaces 1a-1b and 2a-2b having a diameter larger than a radius of the rolling bodies 5 and 5'. In the respective rolling bodies 5 and 5', an outer diameter becoming a rolling contact surface also has curvature in the shaft direction. The rolling bodies 5 and 5' adjacent on the circumference are alternately arranged across each other. The outer diameter of the respective rolling bodies respectively contacts at two points in total by one point on the raceway surface of always opposed one bearing ring and the raceway surface of the other bearing ring. A value of a contact angle of one directional rolling body 5 and an inner-outer race raceway surface 1a-2b arranged across each other on the circumference is set different from a value of a contact angle of the other directional rolling body 5' and an inner-outer race raceway surface 1b-2a.
