Nexen Group, Inc. has introduced the Precision Ring Drive Indexer, or PRD, a highly flexible, durable and efficient alternative to direct drive motors capable of 2x faster indexing than competitive indexing options. Unlike most cam drive systems, the PRD can start and stop at any incremental position. The motion profile is quickly and easily changed by simply loading a new servo drive program into the system. As a result, it delivers precise and flexible indexing and rotary positioning ideal for a wide range of welding, positioning system, medical product, automotive, aerospace and semiconductor applications.

“Not only is the Precision Ring Drive Indexer efficient, precise and flexible; its robust design minimizes maintenance requirements to help users maximize machine and process productivity,” adds Tony Kliber, Engineering Director, Precision Motion Control Products. “We eliminated oil baths to reduce time-consuming cleanups. We also designed the PRD so it can be mounted in any orientation – and the large hollow center allows it to be easily mounted with cabling through the center of the rotating plate.”

The PRD combines Roller Pinion System technology with a precision-grade bearing and gearhead. The PRD table is supported by a high capacity cross-roller bearing rated for loads up to 1,575 kN. It’s capable of speeds up to 94 rpm and can handle peak torque inputs at any time.
