GCA2-50-F2 Intelligent Servo Force-Control Electric Cylinder (Compact Type, Single Linear Bushing Series)
Precision Rigidity, Microgram-Level Touch — GCA2 Series Intelligent Servo Force-Control Electric Cylinder
Built-in High-Power Servo × F2 Compact Single Linear Bushing × ±1g Ultra-Precision Force Control. Setting a new benchmark for 50mm stroke, highly cost-effective, and flexible precision assembly.
Breaking the bottleneck of rough traditional pneumatic force control and bulky external sensors, GAO GONG brings you a brand-new, highly integrated, closed-loop transmission solution.
I. Product Overview
GAO GONG GCA2-50-F2 series intelligent servo force-control electric cylinder is a cutting-edge execution component specifically engineered for industrial assembly, pressing, and testing applications where installation space is tightly restricted, and high-precision flexible force control must be balanced with outstanding cost efficiency.
This product deeply integrates a high-power servo motor, a high-resolution absolute encoder, and self-developed force-control algorithms into the F2 compact-profile housing. The internal guidance mechanism features a specialized single linear bushing structure that minimizes operational friction and eliminates motion dead zones. Optimized for a 50mm stroke configuration, it delivers exceptionally smooth reciprocating motion and achieves an industry-leading repeatability of ±0.005mm. Furthermore, it pushes force-control precision down to the ±1g level, enabling gentle "soft landing" and micro-force feedback without requiring external sensors, thereby perfectly safeguarding your core high-value, fragile workpieces.
II. Eight Core Technical Advantages
Built-in High-Power Servo Motor — Powerful Performance, Compact Footprint
The industrial-grade high-power servo motor is perfectly concealed inside the cylinder housing. The compact, integrated structure significantly releases space inside your equipment while delivering ultimate dynamic response and high thrust output.Standard Absolute Encoder — No Homing Required After Restart, Safe and Efficient
The entire series comes standard with an absolute encoder featuring power-off position memory. In the event of an unexpected power outage or system reboot, there is no need for tedious and hazardous "homing" routines, effectively eliminating crash risks and maximizing production uptime.F2 Compact Single Linear Bushing — Ultra-Low Friction Across 50mm Stroke
The guidance mechanism utilizes a compact-profile layout with a single linear bushing. It provides exceptionally smooth linear motion and minimizes mechanical resistance during the full 50mm travel, offering outstanding cost efficiency for long-cycle testing and continuous pressing.Sensorless High Integration — Cost Reduction, Risk Elimination
Based on full closed-loop control logic, the electric cylinder operates flawlessly without any external limit switches or home sensors. While simplifying electrical wiring and lowering hardware procurement costs, it completely eliminates downtime risks caused by external sensor failures due to environmental interference.±0.005mm Repeatability — Micron-Level Precision Control
Utilizing grinding-grade ball screws and optimized backlash elimination designs, the repeatability is stabilized within ±0.005mm. No matter how many times it reciprocates, it hits the target position with absolute precision.Arbitrary Position Staying in Full Stroke — Flexible Digital Programming
Supports precise deceleration, suspension, or motion switching at any coordinate point within the rated 50mm stroke. The acceleration and deceleration curves are as smooth as silk, and the motion trajectory is fully programmable via the upper-level controller.High-Precision Force Control & Smart "Soft Landing" — Eradicate Workpiece Damage
With bidirectional, high-precision force feedback algorithms, the cylinder instantly switches to force-control mode the moment it detects contact with the workpiece, whether executing downward pressing or upward lifting. It achieves a gentle soft landing with zero instantaneous force overshoot, strictly preventing fragile components from being crushed or damaged.Direct Connection to Upper Controller & Intuitive Interface — Quick Setup for Everyone
The electric cylinder communicates seamlessly with upper-level controllers (PC/PLC). Paired with GAO GONG's customized, intuitive visualization software, engineers can complete process configurations simply by entering parameters, reducing the development cycle by up to 80%.
💡 Groundbreaking Tech Leap: Force Control Precision Down to ±1g
Benefiting from GAO GONG's years of technical accumulation in low-friction transmission, this electric cylinder possesses an incredibly sharp force sense. It stably senses and outputs subtle forces down to microgram and gram levels, tailored specifically for assembling ultra-thin glass, precision semiconductor chips, micro-springs, and other extremely sensitive components.
