Servo Rotary Positioners

GTB Servo Positioning Tables (Direct Drive)


The GTB series compact direct drive servo-mechanical positioners deliver zero backlash, high accuracy for precision positioning applications. The GTB units are orientation independent for flexible mounting supporting trunnion mount and flat table applications. These units feature a wide through hole for utilities with high payload capacity in less space than other servo indexers.
  • Grease-filled, lubricated for life
  • Both horizontal or vertical mounting
  • Large through hole
