-  2. Stick PTFE/UHMW tape to the sliding surfaces of the fixer and the shaft. Then trim the tape to match the surface shape. If you have some damping grease (medium or medium-high stickiness), apply a tiny bit on the sliding surfaces. Turn the M2*6mm screws into the bearing fixers halfway, don’t and never tighten them.
