Bearings CMC Grooved Roller Bearings are the natural fit for any roller screw application. With the incredible force density of roller screws (and the CMC Performance Roller Screw in par-ticular), typically sized bearing supports are in-adequate to react the thrust loads and, conse-quently, the bearing becomes the weak link in the entire system.

'on the rear radial roller bearing- the inner race is tapered as a means to set the pre-load'. I'm hoping what is meant by this is to take out the axial play in the rear roller bearing itself, not to effect pre-load of the spindle itself. Forcing the inner race along the taper would expand the inner race, thus taking out play in the rollers.
