Abstract: A split cylindrical bearing assembly having a first split outer ring with an inner radial self-aligning feature aligning axially with a second split outer ring having an outer radial self-aligning feature, the second split outer ring having two sections that are fixedly assembled and circumferentially aligned. A split inner ring having two sections fixedly assembled and circumferentially aligned is assembled within and axially aligned with the second split outer ring, and a split cage retaining rolling elements disposed between the second split outer ring and the split inner ring. Also the split cylindrical bearing assembly assembled onto a shaft and into a housing assembly.

Abstract: A bearing sleeve assembly for a shaft system, having a bearing assembled between an inner and outer sleeve, the assembly mountable as a unitary sub-assembly or as separate components.

Abstract: An inner ring for a bearing, including: a first portion having a first hardness; and a second portion including an axial end of the inner ring with an axial circumferential edge, a slot for receiving a mounting or fastening device, or a hole for receiving a mounting fastener, an inner portion axially between the first portion and the slot or hole, and an outer portion axially between the slot or hole and the axial circumferential edge. At least one of the inner or outer portions has a second hardness less than the first hardness.

Abstract: A sealed spherical roller bearing assembly, having an outer ring with a seal groove and an inner ring with a central bore. A plurality of rolling elements is arranged between the inner ring and the outer ring. A seal is provided that has a sealing element on an outer diameter of the seal, which sealing element engages in the seal groove in the outer ring.

Abstract: A roller bearing with cage fasteners that prevent cage separation under adverse operating conditions. The roller bearing has an inner race, outer race, a plurality of rollers, a roller cage, and cage fasteners. The inner race is disposed about a rotational axis and includes a peripheral surface facing the rotational axis with an inner nominal diameter of seven inches about the rotational axis. The outer race has a circumferential surface surrounding the inner race and includes an outer nominal diameter of twelve inches about the rotational axis. The roller cage is disposed between the inner race and the outer race and includes a first piece and a second piece connected together by the cage fasteners. Each of the cage fasteners includes a first surface having a first effective area in contiguous engagement with the first piece of the roller cage, and a second surface having a second effective area in contiguous engagement with the second piece of the roller cage.
