Even if a CNC machining center is equipped with spindle bearings that are optimized for a duty cycle at the time of purchase, there is no guarantee the bearings will be optimized for future duty ...

Heavy press fits should be avoided. Accuracy of mounting surfaces should be equal to accuracy of mating bearing surface. Misalignment for low torque and running accuracy should not exceed 1/4°.

They're lightweight with straightness and lateral stiffness that boost stability at higher speeds. Line shafts, also known jackshafts and torque tubes, span long distances to connect other power ...
