Design World is a great resource for industry news, white papers, calculators and many other essential tools for design engineers. Recently, Design World published a formula which can be used to determine the rigidity of a ball screw.

Rigidity is an essential characteristic in ball screw selection.  It can be defined as the amount of elastic deformation the ball screw will experience in the axial direction under a given load. This is important, because elastic deformation affects the positioning accuracy of the system.
