摘要： A roller bearing retainer is constituted by two or a greater number of circumferentially disposed segments. Each segment includes: a plurality of columns provided between mutually opposing long sides of a rectangle; and a plurality of pockets for holding rollers between the columns. At least one of the mutually opposing long sides of the segment includes an arc-shaped connecting member having a generally U-shaped section for slidable fitting in a circumferential direction. The segments are arranged in the circumferential direction, and under this state, the connecting members of each segment is slid over the long side of the adjacent segment, whereby the segments are mutually connected with each other.

摘要： A light weight bearing cage assembly (100) consisting of a plurality of snap-on bridge elements (104) coupled between first and second cage support rings (102A, 102B) conforming to the surfaces of adjacent rolling elements (10). The snap-on bridge elements maintain rolling element (10) in separation, provide rolling element retention within the bearing assembly, and function as a lubrication reservoir between the rolling elements for grease lubricated bearings. Each snap-on bridge element may be individually removed and replaced by snap-on engagement with the first and second cage support rings. Optional locking clips or rings (300, 302) fitted over each snap fitting end of the bridge elements optionally provides additional security against accidental uncoupling of the bridge elements from the first and second cage rings.

摘要： A bearing cage assembly (100) comprises a plurality of discrete bridge elements (206) disposed between adjacent rolling elements (1 12) and coupled between first and second axially spaced cage support wire rings (1 02, 1 04) which are appropriately tensioned. Spacers (1 10) are disposed between adjacent bridge elements and engage the bridge elements in a piloted engagement. The bridge elements maintain a separation between rolling elements, retain the rolling elements within the bearing assembly, and function as a lubrication reservoir for grease lubricated bearings. Profiled surfaces on the bridge elements position the bearing cage assembly on at least one axial end of the rolling elements.

摘要： A rolling element retainer chain provides a row of rolling elements smooth running in a recirculation passage and keeps a predetermined spacing distance between two adjacent rolling elements and the rolling elements be separated without contact to each other; the rolling element retainer chain comprises at least one thin flexible metal strip having a row of longitudinal arranged holes; a row of cross arranged latten between holes are formed thereof; and a number of spacers, incorporated on the cross arranged latten; the strength of the flexible metal strip is much higher than that of the resin materials conventionally used and can endure higher tension without broken, and thus a longer operating duration can therefore be achieved; both ends on the flexible metal strip can be overlapped wholly fixed without interference because of thinner thickness thereof, and a close loop rolling element retainer chain is formed thereof.
