Rods: 0.05mm
Standard practice would be to replace the bearings, but I hear quite a few issues with aftermarket bearings and I wonder about the chances of winding up with worse clearances.
Here are a couple of photos of the bearings.
Can anyone identify the symbol?




No sir , those main shells are no good. As long as the photo is not deceptive, the bearing has a lot of embedded junk. In one of the photos it shows a wear pattern. This should be mirrored on the other side of the shell if the main housing was straight.
