There is a ratio that directly shows the velocity of the screw based on input RPM (rotations per minute.) In high-speed applications a larger screw reduces the RPM, so the larger the screw you use, the lower the potential RPM. Accuracy - A ccuracy is the measure of moving the load to the location while retaining a tolerance level. If you must ...

Critical speed is typically considered after the load, speed, length and end fixity are identified. Here is a quick overview of these factors: Load: Choices include dynamic, static, reaction forces, and any other external forces that may have an impact on the screw itself. Speed: The travel rate, or linear speed of the lead nut. The travel rate ...

Axial play, or backlash, is caused by clearance between the balls and raceways. Using oversized balls in the ball nut can reduce or eliminate backlash. Image credit: NOOK Industries, Inc. Adjustable-diameter ball nuts allow the user to increase or reduce the preload manually, via an adjustment screw that changes the inner diameter of the nut.

Normally, ball screws are used to convert rotary motion into linear motion. Backdriving is the result of the load pushing axially on the screw or nut to create rotary motion. All ball screws, due to their high efficiency, will backdrive. The resulting torque is known as "backdriving torque" and is the torque required to hold a load in position.
