Abstract
This disclosure relates to a bearing unit wherein the rolling elements are supplied with at least one of the raceways, and wherein the rolling elements are formed of a magnetically attractable material and that raceway which is furnished with the rolling elements has been treated to have magnetic characteristics wherein the rolling elements are permanently magnetically attracted to the raceway by a force sufficient to overcome gravitational forces normally urging the rolling elements away from the raceway.
Claims6
A bearing unit particularly adapted for association with a separate race surface, said bearing unit comprising a race member having at least a portion thereof defining a raceway, rolling elements engaging said raceway, said rolling elements being formed of magnetically attractable material, and at least said raceway having magnetic characteristics with said rolling elements being magnetically attracted to said raceway by a force sufficient to overcome gravitational forces normally urging said rolling elements away from said raceway.
