Hi Fellas,
I'm new to the community and I would like to ask if there are any methods ( accepted or otherwise) to reclaim enough Outside Diameter on small journals ( 3/4 " and below ) on shafts that run in small ball bearings. I was on shift last weekend and was asked to see if I could facilitate a running repair on a check weigher ( for small packaged frozen food packages ) . When I stripped the unit down the journal that was running in a 608 2RS ball bearing had worn about 20 thou and I had no spares . The repair had to last a 12 hour shift. By the way I am not a machinist I am a mechanically biased maintenance engineer. The only thing I could think of was to put a knurl on the shaft but I could not get more than 40 percent of the journal because of the wall of the knurling tool holder. My repair worked for 4 hours then failed so I would humbly like to ask some of you obviously elite machinists ( judging by reading many threads ) are there any other methods I could have employed?
Thanks in advance fellas,
Jay.
