Questions about this item

What shaft diameter matches the 3/4 in bore of this CB121816 sleeve bearing?

The bearing fits a 3/4 in shaft; the bore tolerance is held to ±0.005 in so the shaft should be sized for a proper running clearance with C93200 bronze.

Can I run these bearings next to steel shafts that have been in service for years?

Yes, the C93200 (SAE 660) cast bronze works with existing hardened steel shafts; the material handles -450 °F to 500 °F, so normal operating temperatures are well within range.

How do I confirm each bearing is seated correctly after pressing it in?

Measure the installed bore — it should stay within ±0.005 in of 3/4 in — and verify the 2 in overall length sits flush; the bronze colour and C93200 grade marking identify the correct part.
