Not having done this, I would try an auto parts store first with info about or my compressor in hand. The bearings, once removed should have info stamped in them that would allow me to go to a local vendor called Bearings, Inc. in my area, which is where I go to replace that 25 year old bearing in a motor that the OEM wants $85 for as a replacement part and Bearings has it for $7. McMaster-Carr would be another source. The auto parts store may also have these items. maybe someone else like Jazzman will see this thread and throw in hs $02.
