Of all the screws used for industrial motion control, ball screws rise to the head of the class, offering several advantages over other options such as roller screws and acme screws. Featuring efficiencies of at least 90%, ball screws are one of the most economical ways of converting rotary motion into precision linear motion. They’re able to move heavy loads at fast speeds with outstanding accuracy. Moreover, ball screws can be cost-effective alternatives to pneumatic and hydraulic actuators. A ball screw consists of a threaded shaft and a nut, and either one can act as the traversing component. Ball screws work in a similar fashion to ball bearings, where hardened steel balls move along an inclined-hardened inner and outer race. To select the correct ball screw and nut for a specific application, engineers should consider design factors like loads, life expectancy, speed, length, and mountings. Application considerations include lubrication and en...
