Short Answer
Roll-2-Roll electromechanical systems can handle loads up to 30,000 lbs (13,600 kg) with low-friction linear rail bearings.
Roll-2-Roll Technologies electromechanical rewind guides can handle loads up to 30,000 lbs (13,600 kg) when paired with low-friction linear rail bearings (coefficient ~0.01).
Key specifications:
- Maximum thrust: 50–1,500 lbf (222–6,670 N)
- Stroke length: 1–12 in (25–300 mm)
- Maximum speed: Up to 2 in/sec (51 mm/sec)
The critical factor for sizing is breakaway force—the static friction the actuator must overcome to start moving the loaded stand. Using low-friction linear rail bearings dramatically reduces the required actuator size compared to sliding shaft designs (coefficient ~0.25).
For extremely heavy loads, the RLA Series ball screw actuators provide thrust up to 1,500 lbf while maintaining precision positioning.
