Abstract: Construction is achieved that is able to effectively prevent the displacement in the axial direction of a ball bearing 16 that supports the middle section of a pinion shaft 6 so as to be able to rotate freely, and that is compact and low cost. A fastening groove 28b is formed around the entire circumference of a portion near an opening of the inner circumferential surface of a sub housing section 12c of a casing 10c, and a radially outside portion of a C-shaped retaining ring 29b is fastened in this fastening groove 28b. As a result, a side surface in the axial direction of a radially inside portion of the retaining ring 29b is pressed against a side surface in the axial direction of an outer ring 18 of a ball bearing 16 that is fitted inside and supported by the inner circumferential surface of the sub housing section 12c. Moreover, a clip 35 having a radially outside arm section 43 and radially inside arm section 44 is mounted in the opening edge section of the sub housing section 12c, and a diameter reduction prevention section 36 that comprises the tip-end section of the radially inside arm section 44 is inserted into a non-continuous area 34 of the retaining ring 29b.

Abstract: A hanger bearing assembly for a shaft assembly includes a plurality of bearing elements arranged around a circumference of a shaft assembly, each bearing element having a bearing element diameter. A bearing inner race is positioned between the plurality of bearing elements and the shaft assembly and extends circumferentially about the shaft assembly. The bearing inner race includes an outer wall interactive with the plurality of bearing elements. The outer wall has a linear profile extending in an axial direction. A bearing outer race is positioned radially outboard of the plurality of bearing elements and extends circumferentially about the shaft assembly. The bearing outer race includes an inner surface interactive with the plurality of bearing elements and having a curvilinear inner surface profile extending in the axial direction.

Abstract: Disclosed systems couple two rotational shafts in axial alignment with each other such that torque can be transferred between the shafts without undesired loading occurring. A shaft coupling system can include an annular mounting housing positioned around a juncture of two rotational shafts with bearings positioned between the shafts and the housing so that the housing prevents radial motion of the shafts while allowing the shafts to rotate about their common axis. One shaft can be coupled to an engine and the other shaft can be coupled to a shaft-driven device such as a hydraulic pump. One shaft can be smaller in diameter and piloted into a recess in the end of the other shaft. In some embodiments, the two shafts have about the same diameter and are linked via a torque coupler within an annular mounting housing that allows rotation but limits radial motion of the shafts.

Abstract: A cage for a roller bearing is provided. The cage has a ring-shaped base body with a plurality of pockets for receiving rolling elements. The base body is formed by two side rings arranged in a defined axial distance and by a plurality of pocket elements, which are located between the side rings. Each pocket element has two face sides designed for contacting a rolling element. The connection between the pocket element and each of the side rings is established by at least one beam joined with one of the side rings and the pocket element. The beam is a positive substance joined with one of the side rings and the pocket element and has a ring-shaped or elliptical cross section in a section perpendicular to the longitudinal extension of the beam.
