# RLA Series > Maximum Thrust for the Heaviest Web Handling Applications. **Last updated:** 2026-03-23 **Source:** https://r2r.tech/products/actuators/rla --- > Maximum Thrust for the Heaviest Web Handling Applications. ## Specifications | Specification | Value | | ------------- | ----- | | Thrust Range | 800 lbf to 1,500 lbf (3,560 N to 6,670 N) | | Load Capacity (Standard Bearings) | Up to 15,000 lb | | Load Capacity (Precision Linear Bearings) | Up to 30,000 lb | | Stroke Length Options | 4 in / 6 in / 8 in / 12 in (100–300 mm) | | Maximum Speed | 0.75–2 in/sec (19–51 mm/sec) | | Drive Voltage | 24/48 VDC (48 VDC preferred) | | Motor Current | 5.5–7 A | | Power Source | MC QD 1180 or SCU6x MxD | | Motor Type | Brushless Bi-polar Stepper, 1.8° resolution | | Actuator Type | Belt + Ball/Roller Screw | | Mounting Options | Pivot / Rod Eye / Clevis | | Terminal Web Guide | Yes | | Intermediate Web Guide | Yes | | Off-Shelf Replacement | Yes | ## Features - Reverse parallel belt-and-pulley design – belt, pulley, and rotary motor driving a ball or roller screw delivers the highest thrust in the Roll-2-Roll actuator lineup: 800–1,500 lbf - Load capacity up to 30,000 lb – with precision linear bearings (15,000 lb with standard bearings); built for the heaviest unwind/rewind stands - Stroke lengths from 4 to 12 inches – available in 4, 6, 8, and 12 in configurations to match specific guide frame geometry and web width requirements - Front and rear mounting options – spherical bearing and clevis mounting at both ends accommodates misalignment under heavy loads - Powered by MC QD 1180 or SCU6x MxD – 5.5–7 A motor current at 24/48 VDC (48 VDC preferred for maximum performance) - Off-shelf replacement – standard pivot, rod eye, and clevis mounting options fit existing terminal guide frame designs ## Benefits - Stop settling for underpowered actuators – the RLA Series delivers 800–1,500 lbf of continuous thrust, enough to position the heaviest webs with precision - Handle every heavy application with one actuator family – from 4-inch strokes on compact rewind stands to 12-inch strokes on wide-web shifting systems, no mixing actuator brands - Eliminate drift under maximum load – ball and roller screw drives maintain positioning accuracy even at full capacity; no creep, no gradual misalignment - Built for the toughest environments – IP54 protection, heavy-duty bearings, and robust construction perform in paper mills, steel processing, and heavy converting operations ## Applications - Heavy rewind stands — positioning for rewind/unwind systems handling rolls up to 30,000 lb - Large roll shifting — lateral movement of heavy roll stands and shifting frames - Unwind/rewind systems — terminal web guiding at the entry and exit of high-capacity converting lines - High-load terminal guides for paper mills, steel processing, and heavy converting operations ## Documentation **3D Model (STEP):** [RLA-050-0600-TG](https://r2r.tech/documentation/3d-models/rla-050-0600-tg.md) **Additional documentation:** - [BLA-0xx-0600-TG 2D Drawing](https://r2r.tech/documentation/2d-drawings/bla-0xx-0600-tg-2d-drawing.md) - [CASE STUDY - Pneumo-Hydraulic Web Guide Upgrade](https://r2r.tech/documentation/case-studies/case-study-pneumo-hydraulic-web-guide-upgrade.md) - [CASE STUDY: Web Guide Upgrade Kit for Aging Web Guides](https://r2r.tech/documentation/case-studies/case-study-web-guide-upgrade-kit-aging-web-guides.md) - [CASE STUDY: Web Guide Upgrade of Pneumo-hydraulic Web Guide for a Slitting Operation](https://r2r.tech/documentation/case-studies/case-study-web-guide-upgrade-pneumo-hydraulic-web-guide-slitting.md) - [LHS-005-0125-LP: 2D Drawing (dxf)](https://r2r.tech/documentation/2d-drawings/lhs-005-0125-lp-2d-drawing-dxf.md) - [LHS-005-0400-LP: 2D Drawing (dxf)](https://r2r.tech/documentation/2d-drawings/lhs-005-0400-lp-2d-drawing-dxf.md) - [LHS-005-0xxx-LP: 2D Drawing (pdf)](https://r2r.tech/documentation/2d-drawings/lhs-005-0xxx-lp-2d-drawing-pdf.md) - [LHS-015-0150-WG: 2D Drawing (pdf)](https://r2r.tech/documentation/2d-drawings/lhs-015-0150-wg-2d-drawing-pdf.md) - [LHS-020-0xxx-RF: 2D Drawing (dxf)](https://r2r.tech/documentation/2d-drawings/lhs-020-0xxx-rf-2d-drawing-dxf.md) - [LHS-020-0xxx-RF: 2D Drawing (pdf)](https://r2r.tech/documentation/2d-drawings/lhs-020-0xxx-rf-2d-drawing-pdf.md) - [LHS-030-xxxx-RF: 2D Drawing (pdf)](https://r2r.tech/documentation/2d-drawings/lhs-030-xxxx-rf-2d-drawing-pdf.md) - [Power Supply Regen Clamp Wiring](https://r2r.tech/documentation/wiring-diagrams/power-supply-regen-clamp-wiring.md) - [RLA-050-0600-TG: 2D Drawing (pdf)](https://r2r.tech/documentation/2d-drawings/rla-050-0600-tg-2d-drawing-pdf.md) - [Roll-2-Roll® Actuators Brochure](https://r2r.tech/documentation/brochures/roll-2-rollr-actuators-brochure.md) - [Roll-2-Roll® Upgrade Kit: Product Brochure](https://r2r.tech/documentation/brochures/roll-2-rollr-upgrade-kit-product-brochure.md) - [Roll-2-Roll® Web Guide Upgrade Kit Product Brochure](https://r2r.tech/documentation/brochures/roll-2-rollr-web-guide-upgrade-kit-product-brochure.md) - [SCU5 MD Wiring with MC QD 1141/1140/1240 + Web Guide Actuator](https://r2r.tech/documentation/wiring-diagrams/scu5-md-wiring-mc-qd-114111401240-web-guide-actuator.md) - [SCU5 MD Wiring with MC QD 1180/1181/1211/1230/1231/1260 + Regen Clamp + Unwind/Rewind Actuator](https://r2r.tech/documentation/wiring-diagrams/scu5-md-wiring-mc-qd-118011811211123012311260-regen-clamp.md) - [SCU5 MD Wiring with MC QD 1180/1181/1211/1230/1231/1260 + Web Guide Actuator](https://r2r.tech/documentation/wiring-diagrams/scu5-md-wiring-mc-qd-118011811211123012311260-web-guide-actuator.md) - [SCU6x MxD Wiring Diagram with Unwind/Rewind (Small Load)](https://r2r.tech/documentation/wiring-diagrams/scu6x-mxd-wiring-diagram-unwindrewind-small-load.md) - [Servo Center Servo Installation](https://r2r.tech/documentation/manuals/servo-center-servo-installation.md) - [Unwind/Rewind Guides Brochure](https://r2r.tech/documentation/brochures/unwindrewind-guides-brochure.md) - [Unwind/Rewind Installation Checklist](https://r2r.tech/documentation/manuals/unwindrewind-installation-checklist.md) **Tags:** Actuator, RLA, 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). - Website: https://r2r.tech - Phone: +1 (888) 290-3215 - Email: sales@r2r.tech
