1. A mechanism comprising:
a shaft; a bearing assembly rotatably supporting the shaft, with the shaft projecting outwardly from the bearing assembly along an axis to present a shaft end having an axially endmost shaft margin; and a bearing cover removably attached relative to the bearing assembly, said bearing cover including:
a flange,an outer wall spaced axially outwardly from said flange,an at least substantially continuous side wall extending between and interconnecting the outer wall and the flange, anda magnet associated with the flange,said side wall and the outer wall at least in part cooperatively defining an interior space,said shaft end being received in the interior space such that the endmost shaft margin is positioned in the interior space,said magnet removably retaining the bearing cover relative to the bearing assembly such that the bearing assembly is at least in part covered by the bearing cover,said bearing cover comprising a non-magnetizable material,said bearing cover further comprising metal particles embedded in the material,said particles being dispersed throughout the bearing cover so that the bearing cover or a separated portion of the bearing cover is detectable by a metal detector. |
