Your application may lend itself to the use of conical bearings, which can save valuable space by applying both radial and axial forces from the same bearing. SKF has supplied conical bearings capable of handling simultaneous loading up to 8,900 N (2,000 lbf) radial and 17,800 N (4,000 lbf) axial.
The conical bearings shown above provide 350 N (78 lbf) capacity in the radial direction, and 450 N (100 lbf) capacity in the axial direction for a vacuum pump running at 38,500 rpm.
