7" to 15"

Rotary Index Tables

These rugged, low profile pneumatic Rotary Indexing Tables are the perfect fit for your next assembly or machining project. The “shot pin” locking mechanism assures a positive and accurate locking position, while the index cylinder delivers a smooth and controlled indexing motion. All these functions operate without the use of electric motors or controllers.

Applications: Transferring, Filling, Conveying, Feeding, or Indexing of parts for the machining and/or assembly operations. Can be mounted in a vertical or horizontal position.

Standard Features & Options

Standard Features

  • Tapered Roller Bearing Construction
  • Postive Index, Postive “Shot Pin” Locking
  • +/- .001″ Accuracy at Table Top Diameter
  • Two Electric Microswitches To Sense Indexing and Locking Positions
  • Up to 24 Indexing Stations Available
  • Clockwise Rotation

Available Options

  • LFLS Wear Bearing (Low Friction Load Surface) – Reduces rotary friction and doubles load carrying capacity
  • Shock Absorber (10″ and 15″ only) – Mechanical device mounted on blind end of index cylinder to absorb high shock loads (Clockwise rotation only)
  • Sub plates – Aluminum or steel tooling plates, mounted or unmounted, with or without fixture mounting holes
  • Pneumatic, Oil-tite or Explosion-proof limit switches (micro switches are standard)
  • Power System (PS-E) which includes F-R-L, 120V Solenoid Operated 4/2 Directional Valve, Muffler, and Air Tubing.  Note: Solenoid valve available in 24vDC, please consult factory.

Indexing Tables Sequence of Operation with Animation

  1. The directional control valve is shifted by the pilot or solenoid signal. This causes the locking cylinder to retract, unlocking the table. Note: The signal to the solenoid or pilot must be maintained until the table top has completed its movement.
  2. With the locking cylinder of the index ring, the index cylinder retracts, moving the index arm which in turn rotates the table top.
  3. After the index cylinder is fully retracted, the directional control valve is shifted back. This forces the locking cylinder forward and locks the table into position. When the locking cylinder locks the table into place, it pushes the index pawl out of the index ring.
  4. With the index pawl clear of the index ring, the index cylinder moves forward until it hist the stop rod. When the stop rod is adjusted properly, the index pawl is spring activated into the next slot on the index ring and the index cycle is complete.
  5. The index table is now ready for the next index cycle.
