Ball Screw Jacks | Uni-Lift Jacks

UNI-LIFT ball screw jacks provide high efficiency and high speed in a linear positioning package up to 100 tons. The low friction ball screw and nut design provides longer life at load and requires less power to achieve a specified thrust and movement. Ball Screw Jacks can be used individually, in tandem or as part of a larger mechanical system.

Why Lead Screws Are The Best Fit For Many Linear Motion ...

the screw must rotate to achieve the same linear displacement is reduced on a high helix screw. A disadvantage of a high helix angle is that more torque is required to turn the screw. Ball bearing screws can be backdriven. A load on the nut will drive the screw because of the inherent high efficiency (90%).

Ball Screws - Moog Inc.

A ball screw is a rolling system consisting of a threaded shaft (screw) and a nut that, internally threaded as well, contains a determined number of balls. The return of the balls that run in the nut during the rolling is permitted by one or more mechanical elements called liners. A ball screw is similar to a ball …

How to Size and Select Ball Screws: An Engineer's Guide

Because ball screws are a bearing system, they'll need some type of lubrication to avoid metal-to-metal contact of the balls in the raceway. While the lubrication choice can be either oil or grease, it's advisable to avoid solid additives (such as graphite) as they will clog the recirculation system.

Ball Screw Terminology - Dynatect Manufacturing Inc.

Ball Screw vs Acme Lead Screw: A ball screw is a mechanical device that translates rotational motion to linear motion. Ball screws are typically 90% efficient at converting input torque to thrust. Compared to lead screws, ball screws are generally more bulky, because of the need to have a mechanism to re-circulate the balls.

Ball screw - Wikipedia

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction.A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.
