Moreover, we discussed how the dynamics of the spindle are affected by the eccentricity of the belt pulley, the extended length of the milling tool, and the position of the intermediate bearing set. The research results can benefit the structural design of the spindle, optimize the bearings selection, as well as improve the machining accuracy.

Vibration Technology. Heinz P. Bloch, in Petrochemical Machinery Insights, 2017 Recommended Values and Settings. Shaft vibration imposes additional load on bearings and coupling components. For turbine generators in the 410 MW size range, a test stand limit of 2 mils is readily achievable for manufacturers that use uptodate rotor balancing and equipment design methods.

The result is that SKF spherical roller bearings for vibrating applications can tolerate vibration levels of up to 125g (shaft diameter 40 mm) and up to 54g (shaft diameter 300 mm) when subjected to rotating acceleration. With linear acceleration, the equivalent values are around 31g or 15g respectively. Less maintenance.
