Rolling ring linear drives are used worldwide, to meet a variety of positioning and reciprocating linear motion applications. These linear drives convert the rotary motion of a smooth, threadless shaft into linear output at fixed or variable pitch.Typically, rolling ring linear drives reduce a linear motion system's dependency on electronic controls, clutches, cams, gears and so forth (see Figure 1).
