General

SD Series Introduction:

The Servo Driven Dial Indexer is a combination of the time proven RD series indexers with a constant lead cam and servo ready, right angle gear reducer. The cams are hardened and precision ground for optimum performance and rugged durability. All of the bearings are oversized for maximum stability and extended life.

Use the servo motor and drive of your choice. We’ll supply the mounting flange and coupling to suit your needs.

The Stelron SD Dial Indexer provides flexibility, durability and precision for demanding servo indexer applications.


Standard Features:

  • Large steel cam, hardened and CNC profile ground
  • Low profile housing – machined on all mounting surfaces
  • Universal mounting on any of (5) sides
  • Large through hole for pneumatic, vacuum, and electric lines
  • Many standard sequences using modified sine
  • Oversize turntable bearing for dial support and greater resistance to thrust, radial, and moment loading
  • Standard accuracy of +/- .001 @ 6″ radius

General:

The RD indexer design incorporates the highest degree of application versatility available today. One of the standard features include a large through hole for pneumatic, vacuum, and electric lines. The housing is low profile, machined on all mounting surfaces, and provides universal mounting on any of five sides. The indexing cam is made of the finest quality steel. This steel provides deep uniform hardness in a high strength wear resisting matrix. The cams are also CNC profile ground for high accuracy and excellent surface finish. This ground and hardened steel cam provides remarkable service life for the Stelron RD indexer

Construction:

The RD series index drive is the best choice for the speed and accuracy required by the new generation of high speed machinery. The indexer uses the time proven barrel cam as the heart of the drive. Reliable can indexing technology provides higher speeds then pneumatic and electric indexing. Cam operated devices require much less maintenance then pneumatic drives, at a fraction of the cost incurred by electric indexing.
