Perfect groove size for 4.7mm brake line
7 of these are being used in a 4.7mm brake line tubing straightening jig. The tubing material is copper-nickel, so the steel outer bearing groove has no difficulty at all straightening it out. They work great, even though the mounting hole is only 4mm, but I'm using M4 10.9 allen head screws, so 7 of them working together is strong enough.
