Ball Screw Vs Jack Screw

Consider the inherent traits of each type of jack to determine the ideal solution for your application.

Ball screw vs jack screw. Ball screw jacks are used in many of the same industries as machine screw jacks. Also in this video is a bit about two basic types of screw jacks. Ball screw jacks use a ball screw and nut made from hardened alloy steel with bearing balls carrying the load between nut screw. Be sure to verify that the brakemotor selected has sufficient brake torque for your application.

Once loads duty cycles and travel speeds are established engineers and designers must choose the type of jack to select ball screw or machine screw. In this video jonathan kasberg talks with lisa eitel of design world about how ball screw jacks compare to machine screw jacks. Choose a ball screw jack if you have a higher duty cycle faster travel speed typically 20 200 inches per minute and do not require a self locking screw. This rolling action reduces the friction between nut and screw permitting smooth and efficient load movement that requires approximately 1 3 less torque than a machine screw jack with the same load.

Ball screw jacks differ from machine screw jacks in a few key ways. Ball screw jacks are self lowering. Machine screw jacks are typically used to move heavy loads in low duty cycle setups and low speed applications. Machine screw jacks vs.

A brake of sufficient torque is required to hold the load with a ball screw jack.
