Gomexus Power Knob 45 - 47mm

This is my 2nd 45mm knob. The 1st knob I got had 2 bearings the same and one bearing same size, but the inside diameter was slightly smaller. The 2nd knob however all 3 bearings were the same size and inside diameter. The bearing that should have a smaller inside diameter is for the middle of the knob, which holds the shaft from having any play. So one of my handles has a slight play on it.
