Rotary indexing ring CRD/PRD series

belt-drivefor stepper motors

Compact Ring Drives (CRD) are smaller open center indexing or positioning rotary units that combine Roller Pinion technology with two bearing options, two reducer (planetary & Harmonic), or even a reducerless direct drive motor. They provide a range of high positional accuracy, acceleration, load capacity, and speed. Zero backlash. IP65 rating and can operate in any orientation. Only the load bearing needs periodic maintenance. Precision Ring Drive Indexer (PRD) (55) Precision Ring Drives (PRD) are large open center indexing or positioning rotary units that combine Roller Pinion technology with a heavy duty cross roller slewing ring bearing. They provide high positional accuracy, zero backlash, high load capacity, and can operate in any orientation.
