Ring drive handles high torque and speed

The Compact Ring Drive (CRD) system, with precision grade bearing and drive mechanism in a sealed housing, is easily programmed. The three-drive design allows the CRD to handle high speed, high torque or both, depending on the application. With a 250 or 350 mm dial plate bolt circle diameter and a large open center, users can optimize performance in a small space. The combination of roller pinion technology with integrated bearing and motor/gearhead deliver a rigid, smooth system with zero backlash options from the motor through the driven load. The CRD suits applications including cutting systems, gantry systems, medical products, robotics, aerospace, machine tool, semiconductor and material handling.
