I. Core Structural Design: Precision Engineered for Excellence

• Embedded Ball Screw System: The Heart of Our Linear Actuator
  At the core of this sophisticated linear actuator is a preloaded C7-grade precision ball screw system (with C5-grade optional). Available with screw diameters from 16-40mm and leads from 5-20mm, this design ensures a remarkable ±0.01mm repeatability accuracy, even under demanding multi-point positioning scenarios (≥3 points). The integrated alloy base features a built-in screw guide groove, specifically designed to suppress high-speed vibration and significantly reduce the risk of resonance through optimized structural rigidity. This robust construction makes the GCH-120 a highly reliable linear slide actuator.

• Low-Noise Operation Technology: A Silent Electric Linear Actuator
  Experience tranquility with our advanced noise reduction design for the ball circulation path, complemented by a polymer sealing strip. This innovative combination results in an operational noise level of ≤40dB (under 30% load conditions), making this electric linear actuator perfectly suited for noise-sensitive environments such as medical testing equipment and laboratory precision instruments. The motor direct connection/folding installation compatible design further minimizes transmission chain noise, ensuring the GCH-120 performs as a truly silent electromechanical linear actuator.

• Semi-Enclosed Protection: Durability for Your Linear Actuator
  The GCH-120 linear actuator features a robust semi-enclosed design, incorporating a top removable dust cover and side labyrinth seals. This configuration provides an IP40 protection level, effectively balancing optimal heat dissipation with superior dust isolation requirements, ensuring the longevity and reliability of your linear slide actuator.

III. Application Scenarios and Advantages: The Versatility of Our Linear Actuator Solutions

The GCH-120 linear actuator offers significant advantages across a range of critical applications:

• Precision Manufacturing: Ideal for semiconductor wafer multi-point calibration platforms and optical lens coating equipment, relying on its exceptional ±0.01mm level positioning stability. This linear slide actuator ensures flawless production.

• Medical Automation: A perfect fit for medical device assembly lines and silent inspection benches, meeting stringent ≤40dB noise restrictions. This electric linear actuator enhances patient comfort and diagnostic accuracy.

• Long Stroke and Heavy Load Solutions: This robust electromechanical linear actuator can replace traditional hydraulic positioning mechanisms, precisely transferring loads up to 120kg within an impressive 2500mm stroke, offering superior control and efficiency compared to older systems. It truly serves as a reliable high speed linear actuator for demanding tasks.

IV. Technical Considerations: Maximizing Your High Speed Linear Actuator's Performance

• Speed-Stroke Balance: The critical speed of this linear actuator is inversely correlated with screw length. For instance, with a 2500mm stroke, the speed must be carefully controlled below 0.8m/s to maintain optimal performance.

• Inertial Load Management: When acceleration exceeds 0.3G, the handling mass needs to be adjusted downwards to prevent positioning deviation caused by impact, ensuring the consistent accuracy of your electromechanical linear actuator.

The GCH-120 module provides a high-precision, low-vibration positioning solution for heavy-load and long-stroke scenarios. Through the seamless integration of an embedded screw structure and advanced noise reduction technology, this linear actuator stands out as a superior linear slide actuator, an efficient electric linear actuator, a reliable electromechanical linear actuator, and a capable high speed linear actuator for your most challenging projects.
