What is a Belt Driven Linear Actuator?

A belt-driven linear actuator utilises a sophisticated system to transform rotary motion from a motor into precise linear movement.

Consisting of a timing belt connected to two circular pulleys, this mechanism seamlessly transfers torque from the motor while preventing slippage.

A carriage, mounted on profiled linear guides, traverses along the actuator, propelled by the converted linear force.

This setup, with the drive shaft perpendicular to the actuator’s side, ensures smooth and controlled movement, ideal for horizontal applications requiring speed and precision.

Applications of Belt Driven Linear Actuators:

1. Manufacturing Automation

Belt-driven linear actuators find their niche in manufacturing automation, where swift and precise motion is essential for tasks such as conveyor systems, packaging, and assembly lines.

Their ability to maintain high speeds over long distances makes them indispensable in streamlining production processes.

2. Material Handling

From heavy load transportation to precise positioning in warehouses, Belt Driven Linear Actuators offer the speed and reliability necessary for efficient material handling operations.

Their versatility and robustness make them ideal for a variety of material handling tasks, ensuring seamless operation and increased productivity.

3. Printing and Packaging

In industries demanding consistent and high-speed motion, such as printing and packaging, belt-driven linear actuators play a pivotal role.

Their ability to deliver precise positioning of print heads, cutting tools, and packaging machinery ensures optimal performance and quality output.

4. Robotics

From CNC machines to robotic arms, Belt Driven Linear Actuators serve as the backbone of robotic systems, enabling intricate movements and tasks with unparalleled speed and accuracy.

Their compatibility with various control systems makes them the preferred choice for robotics applications demanding dynamic linear motion.

Features of Belt Driven Linear Actuators:

1. Long Stroke Capability

Both our standard belt drives and bridge module units excel in applications requiring extended travel lengths.

With stroke lengths exceeding 18 meters, our Belt Driven Linear Actuators offer unparalleled versatility, catering to a wide range of motion requirements.

While challenges may arise with longer lengths above 20m, our innovative design ensures minimal sagging and maximum efficiency, opening new possibilities for expansive applications.

2. High-Speed Performance

When it comes to speed, Belt Driven Linear Actuators are a brilliant solution. Capable of achieving speeds of up to 4m/s, our Line Tech LM belt actuator sets the benchmark for rapid motion in high-speed applications.

Whether it’s conveyor systems or high-speed sorting, our actuators deliver unmatched performance, ensuring optimal throughput and productivity.

3. Precision and Repeatability

While ball screw actuators boast superior accuracy and repeatability, our Belt Driven Linear Actuators offer commendable precision for a wide range of applications.

With backlash and belt stretch mitigated to achieve repeatability as low as 0.05mm, our actuators guarantee consistent and reliable performance, meeting the demands of most precision-oriented tasks.

4. Dynamic Load Capacity

Despite the perception of lower load capacity compared to ball screw systems, our Belt Driven Linear Actuators defy expectations with their robust design.

Utilising profiled linear rail guides, our actuators exhibit exceptional dynamic load capacity, ensuring reliable operation even in demanding environments.

However, careful consideration is advised for applications prone to shock loads, where additional precautions may be necessary to prevent belt slippage.

5. Mounting Orientation and Z-Axis Considerations

Choosing the right actuator for vertical applications requires careful evaluation of mounting orientation and safety considerations.

While ball screw actuators offer inherent safety features against backdriving, our Belt Driven Linear Actuators can be tailored for vertical applications with added braking systems for enhanced safety.

Additionally, our Z-axis-specific actuators feature innovative designs, reducing mass and inertia for higher acceleration and speed, ideal for dynamic linear motion profiles.
