RLA Series
Maximum Thrust for the Heaviest Web Handling Applications.
10+ Years R&D
1000+ Installations
Setup in <5 Minutes
Key Features
Technical capabilities designed for precision and reliability.
- 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
Key Benefits
Measurable business value and operational improvements.
- 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
