I just learned that both motors work fine. Both almost jump when
powered.

How can I know that a motor is made for driving a belt (and is
able
to
take side loads)?

Baldor might have the belt load data (as a function of the distance
from the bearing). If not, you can look up the dynamic load rating
for
the bearings, measure the distance between them and where the load
will be applied, then calculate the bearing load for an
approximation

With appropriate safety factor : )


Remember the bearing load is 2X the belt tension...

All that's assuming the shaft will not bend....
