Abstract: A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange on the inner race ring at one axial end, and a flange on the outer race ring at an opposite axial end. At least one of the flanges, or an end of the roller, has a profile including a principal segment with a reference point C defining a contact location between the roller and the flange, the principal segment having a continuously changing radius of curvature, on both sides of reference point C, that decreases as a distance from the reference point C increases.

Abstract: A roller bearing includes an inner race ring, an outer race ring, and a roller arranged between and in contact with the inner and outer rings. The bearing has a flange (31,131) on the inner race ring at one axial end, and a flange (21,121) on the outer race ring at an opposite axial end. One of the flanges, and/or an end of the roller, includes at least one principal segment (53,153) intermediate two additional segments (52,152; 54,154). The principle segment is tangentially blended with the two additional segments, and the principle segment has a first curvature that is different from the respective curvatures of the two additional segments. A non-elliptical contact footprint can be obtained by composite profiles at the contact location between the roller end and the mating flange face.

Abstract: A bearing retainer subassembly for use between inner and outer bearing races of a rolling element bearing comprises rolling elements, a bearing retainer, and biasing elements within the bearing retainer for biasing the rolling elements toward one of the inner and outer bearing races to extend a zone of contact between the rolling elements and said one bearing race. The biasing elements may be compression springs, finger springs or similar devices and spacers for applying force on the rolling elements or on aligning pins penetrating the rolling elements to move the rolling elements.

Abstract: This is a multirow bearing for supporting a work or back-up roll of a rolling mill. A seal case is fitted within the annulus between the inner races and outer races. The seal case is configured to fit entirely within the annulus. The seal cases have elastromeric portions which cooperate with an inner race to form barriers at the ends of the bearing.The inner races may comprise a pair of inner races separated by a sealed spacer.
