GTB Servo Indexers

Rotary Positioning & GTB Servo Indexers

Rotary positioning systems play a crucial role in industrial automation by enabling precise, repeatable movement in manufacturing, assembly, and testing processes. These systems are essential for applications requiring high accuracy, controlled acceleration, and smooth motion.

The GTB Series Servo Indexers by Destaco are high-precision, compact, and lightweight programmable servo positioners designed to meet the demands of high-inertia load applications. These zero-backlash, high-torque indexers ensure exceptional accuracy and durability, making them ideal for industrial automation.

Key Features & Benefits:

1.     Zero Backlash Design:

• Uses a globoidal (roller gear) cam mechanism for smooth motion and superior accuracy.
• Preloaded system ensures stiffness and long-term durability.

2.     Flexible Mounting Options:

• Supports horizontal, vertical, trunnion, and inverted mounting for easy integration into different machine configurations.

3.     Two Drive Options:

• High-Torque Gear Drive: For applications with large inertia requirements while keeping the motor small.
• Direct Drive: Provides zero backlash, high precision operation.

4.     Wide Compatibility:

• Easily integrates with servo motors from brands like Allen Bradley, Siemens, FANUC, Yaskawa, Mitsubishi, and Keyence.

5.     High Torque and Load Capacity:

• Can handle high static torque, moment loads, and radial loads, making it suitable for heavy-duty automation tasks.

6.     Lubricated for Life:

• Requires minimal maintenance and is designed for long-term operation.
