Generally speaking, how do Sintered Bronze bearings compare to
ball bearings for radial/perpendicular loads?

Thanks.

How much load and what kind of speed along with type of lubricant
supply would be pertinent questions. You can get quite good wear if
the load is constant but not heavy, the RPMs are moderate and oil is
supplied so that the wedge effect doesn't go away. Roller bearings
are used where there's really heavy and/or intermittent loads(like a
car wheel hitting potholes), constant lubricant supply is hard(ditto)
or where a constant film of lube can't be maintained. For decades,
don't forget, railroad cars used plain bearings with stuffing boxes
filled with oily waste for lube. Same with old-timey overhead belt
drives in machine shops, not a roller bearing to be seen. Not to
mention main bearings on most car engines. They're not sintered
bronze, but ARE plain bearings, as long as oil pressure is maintained,
they don't wear.

Archive.org has some elementary books on bearings, lubrication, and
design of same, might be some downloads would be in order.
