bearing housing freedom
(OP)
Hello,
I am looking for ideas on how to have a bearing housing held but be able to have orbital motion? Any ideas?
Thanks

If you don't want the friction, you could support the bearing with 3 radial springs

please define orbital.

A fairly traditional approach is to eliminate 1 middle bearing and provide a radially stiff, easy to bend coupling (Disc coupling, single element gear, u-joint) at the shaft joint. That way one end of one shaft is "hung" off the fully supported second shaft. No wobble or constrained bearing fight.
Vertical multi-stage pumps often use a threaded coupling at the motor attachment. Ground shoulders or shaft ends run pretty true when butted together (but installed runout MUST be checked). The first pump bearing is still usually many shaft diameters away from the coupling.
