CSG Series: High-Rigidity Miniature Linear Actuators

Compact Power for High-Precision Industrial Environments

The TOYO CSG Series is engineered to bridge the gap between miniature footprint and industrial-grade rigidity. As a "Field-First" tiny cylinder solution, the CSG series integrates a high-precision linear guideway directly into the body, ensuring perfectly guided linear motion and superior resistance to rod rotation. Unlike standard miniature cylinders that can flex under load, the CSG Series maintains its structural integrity, making it the ideal choice for micro-pressing, delicate parts assembly, and high-frequency testing fixtures.

Why Choose the CSG Series?

When machine space is at a premium, engineers often face the challenge of finding an actuator that is small enough to fit but strong enough to last. The CSG Series provides a no-compromise solution. Its compact aluminum body houses high-durability internal components that deliver long service life and consistent ±0.02mm repeatability. By providing the mechanical strength of a much larger cylinder in a fraction of the space, the CSG Series enables higher-density machine designs without sacrificing performance.

Core Performance Highlights

• Integrated Linear Guidance: Dual internal bearings provide exceptional torsional rigidity and eliminate the need for external guide rods.
• Micron-Level Precision: High-efficiency ball screw drive ensures repeatable accuracy for complex electronic and medical device assembly.
• Compact High-Output Design: Delivers significant thrust and speed capabilities despite its ultra-compact dimensions.
• Durable Industrial Build: Optimized for continuous high-throughput operations in demanding semiconductor fabrication and automated testing.

Key Benefits

• Maximized Rigidity: Built-in guideways prevent rod rotation and handle offset loads with ease, ensuring long-term positioning accuracy.
• Flexible Integration: The modular mounting design and multi-motor compatibility simplify installation into diverse robotic and machine systems.
• Reduced Footprint: Eliminates the bulk of external guiding mechanisms, allowing for more compact and efficient automated workstations.
• Low Maintenance Operation: High-quality internal components and centralized lubrication extend service intervals and reduce total cost of ownership.

Engineering Applications & Industry Focus

The CSG Series is the preferred solution for guided motion in precision-focused industries:
