· One way to produce preload in a ball screw assembly is to use a double ball nut, with either a spacer or spring between the two nuts. Image credit: THK. Double ball nut designs produce preload in one of two ways: through tension between two single nuts, or through an offset in the lead of a single nut. The first method uses a spring or a spacer to create tension between two nuts that are ...
