While a standalone rail provides a path, a TOCO Linear Module provides the complete motion solution. These "plug-and-play" actuators integrate the base, the guide, and the drive mechanism into a single precision unit.

For engineers in the 2026 automation space, the choice between the TGH and TGB series is the first step in system architecture.

1. TGH Series: The Ball Screw Drive

The TGH series is designed for applications where precision, thrust, and repeatability are the top priorities.

• Drive Mechanism: High-precision TOCO ball screw.

• Key Advantage: Exceptional positioning accuracy (±0.01mm or better).

• Thrust: Because it uses a screw, it can generate significant force, making it ideal for pressing, vertical Z-axes, or heavy-duty CNC work.

• Speed: Limited by the critical speed of the screw (refer to Article #71).

2. TGB Series: The Belt Drive

The TGB series is the choice for long-stroke, high-speed transport.

• Drive Mechanism: High-strength reinforced timing belt.

• Key Advantage: Speed and length. Belt modules can move at several meters per second and can be manufactured in lengths that exceed the practical limits of ball screws.

• Repeatability: While slightly lower than the TGH (±0.04mm to ±0.05mm ), it is more than sufficient for palletizing, pick-and-place, and logistics.

• Maintenance: Generally lower maintenance as there are no recirculating ball paths in the drive system to lubricate.

3. TGH vs. TGB: The Decision Matrix

4. Selecting Your Motor Mounting

One of the most practical features of the TOCO TGH/TGB modules is the flexibility in motor orientation. Depending on your machine's footprint, you can choose:

• Motor Exposed (BC): Direct coupling for the shortest overall length.

• Motor Side/Bottom (BM/BL/BR): Using a "wrap-around" belt housing to reduce the total footprint of the actuator.

5. Industrial Applications for 2026

• TGH Use Case: A 3C industry testing station where a probe must be placed with micron-level accuracy on a circuit board.

• TGB Use Case: A solar panel assembly line where large, relatively light panels must be moved across a 4-meter span at high speeds.

Conclusion

TOCO’s module lineup is built on the principle of "application-specific engineering." By choosing the TGH for precision or the TGB for speed and scale, you are ensuring that your automation cell is optimized for its specific task.

Always consult the TOCO Model Ordering Method (e.g., TGH4-L1-100-BC) to ensure every detail from lead to stroke is matched to your design.
