Press Fit

[Big Ideas]

If you are looking at thin sheet (.062 or less) be aware that Flanged bearings sometimes have an undercut at the flange. It is possible that a hole of "proper" size is loose because the sheet falls into the relief groove.

Laser cutters and water jet cutters tend to have compensation for cutter kerf. You just have to make sure the part program uses the compensation. It would a shame to have nice holes well located by a CNC cutter and then have to try to keep the accuracy with an expensive hand reamer.

Also, look at parts from Spyraflo. These are self clinching self aligning bearings made to go into sheet metal (or thin wall tubing).
