Babbit is a metal alloy that is poured in molten
form around a shaft in place. It’s like a custom
bushing. I don’t think that’s what you need
for a grinding wheel.

You might be looking for “pillow blocks”. For
a slow thing like that wheel you could make
your own out of hard maple or similar and they
would last a long time.

Split Bushings maybe. But I agree with Loren, make some from hardwood, an oil tropical wood would be best but hard maple will work too.

Hmm,
Suspect the technical name you seek is:
(split) pillow block bearing

Pillow Block bearings are not cheap units and typically designed for heavy duty applications.

Suggest the reason a babbit bearing was suggested is due cost .vs. simple low speed application. For a hand/foot powered grinding wheel a simple bronze/lead bushing would last many years.

Modern equivalent for babbit bearing today is oil impregnated bronze bearing. I like to use MSCDIRECT for this kind of stuff, but McMaster or Grainger carry them as well.

Brass and oil impregnated bronze stock is super easy to machine. You can also buy plain bar stock to make any custom size bearings you need and then simple press them inside a wood/metal housing.

Best Luck.

Thanks guys! Split Pillow Block is what I was looking for, but I ended up using hard maple and so far so good. We’ll see how long it lasts.

I poured some babbitt on an old Hit & Miss motor years ago.
if you have the bearing blocks, there not much to it.
there are probably YouTube videos on how to mold and pour babbitt bearings.

there is a pair of vintage Line Shaft Pillow Block Babbitt Bearings for $10.00 on E-Bay.
