So far the bearing has held up well. It is used on a sheet folding machine to help the sheets coming out of the machine, there is a 3/4 inch spinning shaft running through the pillow blocks to help the sheet get pulled out of the machine. This was added on by me. This picture was taken before the shaft was put on but, the shaft runs from left to right at the same level as the dark metal channel to help pull sheets to the belts.
