## Features

- Non-captive direct lead screw design – converts rotary stepper motor motion directly into linear thrust with no belts, pulleys, or gearboxes to maintain
- NEMA 17 motor (LHS-005) – ~50 lbf thrust for low-profile and compact installations
- NEMA 23 motor (LHS-020) – 200 lbf thrust for intermediate web guides and retrofit replacements
- NEMA 34 motor (LHS-030) – 300 lbf thrust for larger intermediate web guides (80in/2m or higher) or smaller unwind/rewinds and retrofit replacements
- LP (Low Profile) configuration – 50 lbf, 1–4 in stroke, fixed mount for space-constrained intermediate guides and typically used with [Roll-2-Roll® Web Guides](https://r2r.tech/products/web-guides) smaller than 20in or 500 mm
- RF (Retrofit) configuration – 200–300 lbf, 4–12 in stroke, fixed mount and no actuator pivoting (should be handled in the actuator mout) for drop-in pneumatic and hydraulic replacements
- TG configuration – 200–300 lbf, 4 in stroke, front and rear rod eye options for floating mount opion. Easy installation with a pin or sholder bolt in the front and rear to attach the existing fixed and moving frame of the web guide mechanism

## Benefits

- Stop losing production to slow, imprecise actuators – the LHS Series delivers positioning accuracy of ±0.1 mm with speeds up to 4 in/sec, keeping your web on-center without operator intervention
- Eliminate air compressor costs – LHS actuators run on low voltage (24/48V for the driver); no air lines, no compressor, no wasted energy
- Drop in a retrofit replacement – the RF and TG configurations use standard mounting patterns (pivot, rod eye, clevis) so you can upgrade from pneumatic and hydraulic actuators without re-engineering your guide frames
- Fit actuators where others cannot – NEMA 17-based LHS actuators deliver 50 lbf of thrust in a compact package small enough for the tightest web paths
- Simplify your drive electronics – pair with MC QD motor drivers for SCU5 controller or the SCU6x with built-in stepper driver for a clean, integrated system

## Applications

- Intermediate web guides for converting, coating, and printing lines
- Low-profile installations where space is limited
- Compact web guide systems for narrow-web converting and packaging
- Retrofit replacements for pneumatic and hydraulic actuators

## About Roll-2-Roll Technologies

Roll-2-Roll Technologies designs and manufactures patented fiber-optic web position sensors and advanced web guiding controllers — the precision measurement and control core of modern roll-to-roll manufacturing. Spun out of Oklahoma State University's Web Handling Research Center and trusted by Fortune 500 medical, battery, and nonwovens manufacturers, our patented sensors work without recalibration at ±0.1mm accuracy up to 760 mpm — typical customer outcomes are 50%+ less downtime and payback under six months. Headquartered in Stillwater, Oklahoma, our team of PhDs, controls engineers, and industry veterans extends the sensor + controller core into complete web guide systems including stepper-motor-based linear actuators (RLA, BLA, LHS).
