Lead Screw Linear Actuator - LSR0605T-0250-NCF171-NNN-NNN, Non-Captive with Anti-Backlash Nut, 6x5x250mm

Miniature non-captive lead screw actuator with a 6mm screw diameter, 5mm lead, and 250mm length, featuring a non-rotating lead screw that passes completely through the motor assembly to move and accurately position loads. The programmable NEMA 17 single-stack stepper motor (42mm frame size, 39.8mm motor length) incorporates a rotating internal anti-backlash nut that converts motor rotation into linear motion, allowing either the motor assembly to travel along a stationary screw or the screw to move axially through a stationary motor. Position, speed, acceleration, direction, and travel can be programmed using a compatible external motion controller and motor drive.

The precision-rolled 300 Series stainless steel lead screw features a PTFE coating to reduce friction and wear. The internal anti-backlash nut incorporates PBC Linear's Constant Force Technology™, using spring-loaded radial pressure to maintain thread engagement, reduce axial play, and compensate for wear, improving positioning repeatability. The actuator delivers a lead accuracy of 0.003in/ft (76µm/300mm), up to three times better than typical industry specifications.
