Indeed, it is very unusual for products to use any sort of custom bearing as that just adds to the cost unnecessarily and there are so many existing stock bearing parts that such is rarely necessary. If you, or the new owner, pull the existing bearing you should be able to order a replacement simply by looking up the part number printed on the existing bearing.
Appreciate the suggestion, unfortunately I need to start a project and don't have the time to source a replacement. Additionally I can't complain, have gotten my moneys worth from the reconditioned unit. Have already replaced the beast.
