A lack of screw shaft straightness can become a critical factor in any application. Bent lead screws can cause noise, premature wear and failure, high drive torque, and excessive heat. But straightness requirements vary widely from application to application, and straightness is an expensive and perishable product feature. For these reasons it is important to understand what straightness is, how it\\\'s measured, how it can be achieved, maintained, lost, and restored.
