ETK & ENK Series

ETK & ENK Series: Electric Rack & Pinion Actuators

Limitless Travel for High-Throughput Industrial Automation

The TOYO ETK-ENK Series is the definitive solution for large-scale automation challenges that exceed the capabilities of traditional ball screw or belt-driven actuators. By utilizing a precision rack and pinion mechanism, these actuators provide high-speed, high-load motion over virtually unlimited distances. The modular design allows engineers to interconnect rack segments and aluminum extrusions, creating a continuous motion path that can span entire factory floors.

Why Choose the ETK-ENK Series?

When your application requires high-speed throughput across long strokes—such as in 7th-axis robot transfer units, large-format glass handling, or warehouse logistics—the ETK-ENK Series excels where others fail. Belt drives can suffer from stretching and vibration over long distances, and ball screws are limited by critical speed and physical length. The ETK-ENK Series eliminates these constraints, offering a direct-drive pinion system that maintains high rigidity and precision regardless of the total travel length.

Core Performance Highlights

• Scalable Motion Architecture: Standard strokes up to 5700mm are just the beginning; the connectable design allows for custom, extended travel lengths.
• Elite Linear Velocity: Reaches speeds up to 2010 mm/s, ensuring rapid cycle times and high productivity in expansive production environments.
• Direct-Mount Pinion Drive: Transfers power directly from the motor to the rack, maximizing mechanical efficiency and reducing parts wear.
• Heavy Industrial Duty: Robust frame sizes (15, 22, and 30) support payloads up to 185 kg with exceptional stability.

Key Benefits

• Unlimited Stroke potential: Overcome the physical limitations of single-piece actuators with a modular, joinable rack system.
• Minimized Power Loss: Direct transmission eliminates the energy dissipation typical of belt-and-pulley systems.
• Reduced Maintenance: Fewer moving parts and the absence of belts mean less downtime and lower total cost of ownership.
• High Positioning Reliability: Delivers consistent accuracy with repeatability up to ±0.05 mm (ETK series), even at extended lengths.
