I'm having my back axle replaced on my monster; for the bushings that are being machined, I need the dimension of the outside diameter of the inside race on 20mm bearings. Only want the bolt pressure to be on the inside race.

Anyone have that dimension handy? Thanks!!

I think this will depend on who makes the bearings - the measurements I get is:

ID: 20.05mm
Inside Race Thickness: 3.97mm
Inside Race OD: 28.00mm

Hope that helps.

Thanks Kent! Perfect
