摘要： A cage segment for a bearing rotatable around an axis of symmetry that defines an axial direction and able to receive a plurality of rolling elements and having an inner and outer walls that extend circumferentially in the form of a of cylinder. A plurality of radial beams extend globally radially with respect to the axis and connecting the inner and outer walls. Each axial radial beam having a central portion and two end portions that are opposite with respect to the central portion. The central portion being symmetrical with respect to a plane of symmetry. The plane of symmetry of the at least one end portion cooperating with a rolling element to center the segment, forms with the plane of symmetry of the central portion an angle which is not equal to zero.

摘要： A mechanical system with a one-way clutch, such as a motor vehicle alternator pulley, includes an outer first ring and an inner second ring able to move relative to one another in rotation about a central axis and delimit between them, radially with respect to this central axis, an annular housing. The mechanical system includes a free-wheel mechanism having members arranged in the annular housing, and at least one rolling bearing providing rollers arranged in the annular housing. The first and second rings are common to the free-wheel mechanism and to the rolling bearing. The members of the free-wheel mechanism are cams in contact with a first race formed by the first ring and a second race formed by the second ring. The first and second races are circular, centered on the axis of rotation and have no ramp.

摘要： A prong type resin cage includes: an annular portion; and multiple cage bars. Each cage bar has a roller guide face formed in each opposed face thereof, the opposed face being opposed to an outer peripheral face of a corresponding one of rollers. The roller guide face is used for roller guide by the outer peripheral face at a rotational speed equal to or lower than a prescribed rotational speed. A cage outer face including an outer peripheral face of the annular portion and radially outer faces of the cage bars has outer ring guide faces of which diameter is increased radially outward by a centrifugal force to decrease a radial clearance between the outer ring guide faces and an inner peripheral face of the outer ring, so that outer ring guide by the inner peripheral face is carried out, at a rotational speed higher than the prescribed rotational speed.
