SAE 841, aka Oilite, is a sintered bronze and will not hold threads very
well. SAE 660 bronze is also very common and would be a better choice in
this case.

See the bottom of McMmaster page 1018 for steel bushings.

Misumi America is another possible source.

Yeah - I had decided I didn't want the oilite because I *want* friction
since it as attaching a motor shaft to a wheel. Glad to know about the lack
of thread-holding qualities, too.

Thanks !
