ball screw and is a direct consequence of the characteristic frequency of vibration of the ball screw. For example, a 100 inch long 1 inch root diameter ball screw with both ends fixed has a natural frequency of about 18 Hz. With both ends supported rather than fixed the natural frequency of the same ball screw is reduced to about 8 Hz.

The Fundamentals of Ball Screws | Machine Design

Notes on Preloading. Lead shifting manufactures a shift or offset in the lead of the ball nut. For example, a lead might be shifted from 5.00 mm to 5.05 mm to shift the ball bearings in a different direction inside the ball nut. This is the preferred method when considering compactness, but it reduces load capacity.
