bronze bearing flange
Self Lubricating Bronze Bearing 10.02mm Bore 15.9mm Panel Hole diameter SDP/SI A 7Z41MPSB10M
and its 6mm brother have a flange thickness of 0.75mm. The bronze bearing I can get all have at least a flange thickness of 2mm. Is this a problem? Its a bit close next to the pulleys.
Another option would be to use PTFE or POM bearings. These have a flange thickness of 1mm but I'd rather use bronze.
