Removable bearing cover

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, and
• a 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.
