Roller end caps from pvc or nylon Help!

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 them off a little so they can’t spin in the pocket.

I’m not sure how well those materials would stand up against the forces of press fitting, I've not checked your wall thickness either but I would hate to see all that machining only for the caps/material to crack.

It would be best to have the bearings to hand as well, they may say 30mm outside race but I bet their not spot on and would read different on two different callipers. A 30mm pocket with the grub screw method should save some headache, would also allow for easy swapping of the bearings in the future should you need to.
