Bearings will never differ enough to measure with a caliper. I'm pretty sure the tolerance for that size is something in the tenths of micrometers region, so even with a micrometer you'd struggle....

It's easily doable, but my lathe just went up in smoke!

For the bearing tolerance, of the top of my head, you'll need about 0.1 undersize in plastic for it, but plastic can be very much trial and...

Hi Guys,

Just a couple of thoughts, if you are going to press fit the bearings it maybe a better option to fit them by hand but also secure them with a small grub screw from the side, just to lock...

Looks fairly easy to do, however an idea of tolerances are needed.

Is the part to be a pressfit into the roller, or a slight clearance fit to allow it to be glued/bonded in?
Is the recess in the...
