Rotary Indexer

Introducing Patented Precision Rotary Indexer Systems


Unlike some cam driven systems, the Precision Ring Drive System can start and stop at any incremental position. Users can change the motion profile by simply loading a new servo drive program. The Rotary Indexer also allows maximum acceleration or deceleration at any point without the risk of damage.


NEW! COMPACT RING DRIVE INDEXERS

Based on innovative Roller Pinion technology, the CRD Rotary Indexer comes complete with a precision grade bearing and drive mechanism in a sealed housing. Freely programmable, the drive design configurations allow the CRD to be optimized for high speed, high torque or both depending on the application. With a 150, 250, 350 or 550 mm output bolt circle diameter and a large open center, users can optimize performance in a small space.


  • INDEXING PRECISION
  • Up to ±20 ArcSec
  • AND REPEATABILITY
  • Up to ±3.2 ArcSec
  • LOADS TO 1016 kN.
  • SPEEDS UP TO 304 RPM.

ROTARY INDEXERS OFFER HIGHER ACCURACY and REPEATABILITY

The PRD Rotary Indexer models offers all the great features of our other advanced Roller Pinion technology and opens up new design generation machines. PRD table is supported by a high capacity cross roller bearing rated for loads up to 1575 kN. Peak torque inputs at any time allows for indexing times up to 2x faster than the competition.
