Rolling-ring driver are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating linear-motion applications, rolling-ring linear drive are mechanical alternatives to electronically controlled linear-motion drive systems.
Rolling Ring Drives run on a smooth, unthreaded shaft. The rotary input of the motor-driven shaft is converted into linear output by the action of specially machined rolling-ring bearings. The mechanism generating the linear output is friction between the rolling-ring bearings and the shaft.
Smooth Shaft Uint areas：

Rolling ring linear drive can convert rotational motion into precise linear motion. They also work with clockwise and counter-clockwise motion
