  • Spindle bearing follower
    Patent number: 4529324
    Abstract: This invention is a device to reduce the wobble of a rotating shaft disposed in a cavity of a housing which wobble results from a spurious or undesirable positioning of a bearing assembly in which the shaft rotates. The present device includes a bearing follower which is shaped to have a long side which is in abutment with the side walls of the cavity. Accordingly, the follower cannot be readily placed in a cocked or misaligned position. The follower is spring loaded against the bearing assembly which is subject to being cocked and thereby reduces the capability of that bearing assembly to be misaligned.
