    摘要： A ball bearing includes an inner ring having an outer periphery in which an inner raceway groove is formed, an outer ring having an inner periphery in which an outer raceway groove is formed, a plurality of balls interposed between the inner raceway groove and the outer raceway groove, and an annular cage that holds the balls. The cage includes an annular portion positioned on one side in an axial direction with respect to the balls and a plurality of cage bar portions that extend from the annular portion toward the other side in the axial direction. Each cage bar portion has a guide portion that positions the cage by coming into contact with the inner raceway groove in a non-contact area other than an area in which the corresponding ball is in contact with the inner raceway groove.

    摘要： A rolling-element bearing in which a rolling element is retained in each of retaining openings formed in a retainer and method for manufacturing the bearing are provided. Each retaining opening is defined by a pair of inner side faces facing each other, and a pair of inner end faces facing each other. In the manufacturing method, with a support die being brought into contact with one of the inner side faces and the inner end faces of one of the retaining openings, the outer and inner circumferential surfaces of the retainer are pressed by an outer punch and an inner punch. Accordingly, on at least one of the inner side faces and the inner end faces, a first retaining piece and a second retaining piece for preventing the rolling element from falling off are formed on the outer circumferential surface and the inner circumferential surface of the retainer, respectively.

    摘要： A support structure carries a thrust load of a transmission which includes a torque converter having an impeller and a turbine opposite to each other with a stator therebetween. A thrust needle roller bearing having needle rollers arranged in two rows is provided at, at least one of places respectively between the stator and the impeller and between the stator and the turbine. The support structure carrying a thrust load of the transmission, a method of manufacturing the support structure and the thrust needle roller bearing are thus obtained, with an improvement in inflow and outflow of a lubricating oil, a reduction of the differential slip of the needle rollers, and an improvement in strength durability.

    摘要： Material is first formed into a flat ring. Ball retaining pockets are then formed in the flat ring leaving bridge material between adjacent pockets. Bearing balls are inserted into the ball retaining pockets and bridge material between adjacent pockets is then reshaped such that the bridge material wraps partially around the balls, thereby retaining the balls and forming a rigid bridge between adjacent ball pockets. The bridge is proximate a line common to the centers of adjacent balls.

    摘要： The invention contemplates a method of retaining recessed-end bearing rollers in a ductile annular retainer having plural angularly spaced roller-receiving pockets, wherein each pocket extends radially through the retainer and is confined at axial ends by end walls forming part of the annular retainer, there being a local axially outwardly open central recess in the end walls at each roller-pocket location whereby the region of remaining wall material at each central recess is locally relatively weak. The rollers are retained by essentially limiting retainer end-wall indentations to the relatively weak regions.
