Nexen Compact Ring Drive optimized for high speed, high torque or both.

16-June-Nexen-Ring-Drive-625Nexen Group, Inc. introduced its Compact Ring Drive (CRD) system with precision grade bearing and drive mechanism in a sealed housing. Freely programmable, the three-drive design configurations allow the CRD to be optimized for high speed, high torque or both, depending on the application. With a 250 or 350mm dial plate bolt circle diameter and a large open center, users can optimize performance in a small space. The combination of Nexen’s roller pinion technology with integrated bearing and motor/gearhead deliver a system with zero backlash options from the motor through the driven load, the company says. The CRD features indexing precision up to ± 30 ArcSec and repeatability up to ± 5.1 ArcSec. It handles speeds up to 225 RPM and has an output load capacity of up to 108kN.
