Non-Captive Motorized Lead Screw

Anti-Backlash Non-Captive Lead Screw Linear Actuators - LS Series

Anti-backlash non-captive lead screw linear actuators in the LS Series are built for accurate, repeatable positioning where the screw typically rotates to force a stationary, load-carrying external nut to move axially. These actuators use a precision lead screw paired with an industry-leading Constant Force Technology™ anti-backlash nut to reduce play, improve repeatability, and provide more than twice the backlash compensation of conventional nut designs.

Available in NEMA 11, 14, 17, and 23 frame sizes, LS Series non-captive actuators support lead screw diameters of 3/16 in, 1/4 in, 6 mm, 3/8 in, and 10 mm. Optional PTFE-coated or uncoated screws give designers flexibility for different friction, wear, and environmental requirements, while self-lubricating performance helps reduce maintenance in demanding automation, robotics, positioning, and motion control applications.

With lead accuracy up to three times better than standard options, these anti-backlash lead screw actuators deliver smooth motion, long-term reliability, and high-precision linear travel in a compact motor-driven package.
