Abstract:
1. A roller assembly, comprising: a shaft comprising a non-circular cross-section, a bearing comprising an inner race, an outer race, and rotatable elements captured between the inner and outer races, the inner race mating generally with the non-circular cross-section and being clamped to the shaft for rotation therewith, a bearing housing including an annular portion disposed about the outer race so as to support the bearing and having an outer periphery joined to a mounting flange arrangement extending axially, relative to an axis of said shaft, a bearing mount including a vertical wall containing a circular hole disposed concentric with said shaft and including a mounting bracket joined to and extending axially from said wall and being radially outward of said bearing housing in close proximity to said mounting flange arrangement of said bearing housing, said mounting flange arrangement of said bearing housing including at least one axially extending tab, and said mounting bracket being positioned radially outward from the at least one tab, and said fastener arrangement including a fastener securing the tab to said mounting bracket and said mounting flange arrangement of the bearing housing includes a step defined at an end of said at least one axially extending tab such that an axial dimension of the step defines an axial position range, with the mounting bracket including an axially facing edge, and the bearing housing being positioned, such that the edge of the mounting bracket falls within the axial position range, a housing attachment arrangement securing the bearing housing to the mount by a fastener arrangement coupled between said mounting bracket of said bearing mount and said mounting flange arrangement of said bearing housing and exerting a mounting force directed in a plane positioned at a right angle to said axis of the shaft.
