Abstract: A bearing support assembly is disclosed having a support plate with support holes and a column mounting plate with slot openings centered and positionally adjustable in a first direction over the support holes. A mounting plate having mounting slots is perpendicularly affixed at one side of the support plate by mounting bolts which are positionally adjustable in a second direction within the mounting slots. A tubular support column is affixed at one end to the column mounting plate, the interior of the tubular support column containing: a screw adjusting block which is fixedly secured within the tubular support column at the one end, and a slidably engaging support post, one end of which is connected to a bearing clamp, which in turn supports a bearing. An adjustment bolt engages the screw adjusting block and the other end of the support post, where the adjustment bolt is rotationally adjustable in a third direction to vary the vertical position of the bearing support assembly.
