What’s the purpose of a double ball nut?
In its most basic form, a double ball nut is essentially two single ball nuts that have been tensioned against each other to induce preload. Three common methods for inducing preload in a double nut are: With a spacer ring between the ball nut halves With a spring between the ball nut halves By creating […]
Three ball nut recirculation methods
From a design standpoint, the most important criteria when selecting a ball screw assembly is the method used for recirculating the load-carrying balls of the ball nut. The ball nut recirculation method is a determining factor for the smoothness of motion and size of the ball screw assembly. It also has a significant influence of […]
