Systematic Selection Guide for Toyo Electric Cylinders

I. Matching of Core Parameters

1. Load Capacity Calculation

• Static Load: Determined by the weight of the workpiece, fixture weight, and external forces. For example, the CSG25 series has a maximum horizontal lifting capacity of 18kg; when used vertically, it must be equipped with a brake (model suffix with "B"), and the maximum lifting capacity is reduced to 3kg in this case.

• Dynamic Load: Considers inertial forces during acceleration/deceleration, calculated using the formula:$F=m\times (a+g)$

  Where $a$ is acceleration and $g$ is gravitational acceleration. The dynamic load must not exceed 80% of the rated thrust. For instance, the GTY8-L20 model has a rated thrust of 347N; if the acceleration is 5m/s², the maximum horizontal lifting capacity is calculated as:$m=F/(a+g)=347/(5+9.8)\approx 23.4kg$.

2. Stroke and Speed Planning

• Stroke Selection: Determined by actual motion requirements. Toyo electric cylinders have a standard stroke range of 50–800mm (e.g., GTY8 series), and custom strokes can reach up to 2000mm. Note the risk of screw deflection for long strokes (>600mm); it is recommended to reduce speed and add auxiliary supports.

• Speed Matching: The lead directly affects speed and load capacity. For example, the CSG25-L8 model (8mm lead) has a maximum speed of 250mm/s; for a required speed of 500mm/s, a model with a 16mm lead can be selected (but load capacity will decrease by 50%).

3. Accuracy Requirements

• Repeat Positioning Accuracy: Toyo electric cylinders have a standard accuracy of ±0.01mm (e.g., GTY5 series), suitable for precision scenarios such as electronic assembly and semiconductor inspection. For higher accuracy (±0.001mm), closed-loop control models with linear scales can be chosen.

• Positioning Methods: Supports homing (origin determined by torque, no sensor required) and software-configured soft limits to avoid hardware collisions.

II. Adaptation to Environmental and Installation Conditions

1. Environmental Parameters

• Temperature Range: Standard models are suitable for 0–40°C. For high-temperature environments (e.g., injection molding workshops), high-temperature resistant models (e.g., GPH series, IP66 protection, capable of withstanding -20°C to +80°C) should be selected.

• Protection Level: Standard IP54; optional IP65 (dust and water resistant) or IP67 (short-term water immersion) for dusty, oily, or humid environments.

• Cleanliness: CLASS 10 cleanroom-certified models (e.g., CGCH series) meet high-cleanliness requirements in semiconductor and medical fields.

2. Installation Methods

• Mounting Types: Supports surface mounting, embedded mounting, bracket mounting, etc. For example, embedded mounting is suitable for compact spaces, while bracket mounting allows flexible angle adjustment.

• Connection Interface: Compatible with ISO15552 standard flanges for easy integration with existing equipment. High-flexibility cables are optional (e.g., code "03" indicates a 3m power cable).

3. Multi-Axis Coordination

• Control System: The TC100E driver supports EtherCAT bus and can connect up to 16 devices in series for synchronous motion, suitable for multi-axis linkage scenarios (e.g., robot 7th axis, high-precision welding).

• Motion Trajectory Planning: Preset positions via TOYO-Single software, supporting complex paths such as linear interpolation and circular interpolation with an accuracy of ±0.02mm.

III. Drive and Control Solutions

1. Driver Selection

• Differential Signal Control: It is recommended to use differential signals (Line Driver) to reduce interference. If the upper controller only supports open-collector output, an adapter must be selected.

• Homing Mechanism: Supports sensorless homing (origin determined by torque), reducing hardware costs and improving system stability.

2. Software Support

• TOYO-Single: Integrates parameter configuration, motion monitoring, and fault diagnosis functions. It can display real-time current, position, and I/O status, and supports CSV data export.

• Secondary Development: Provides API interfaces for easy integration with MES systems and vision inspection equipment to achieve intelligent production.

IV. Industry Application Cases

1. Semiconductor and Electronic Manufacturing

• OLED Flexible Screen Lamination: The CSG25-L8 model (8mm lead) completes polarizer lamination with ±2μm alignment accuracy, achieving a production capacity of 300 pieces/hour and a yield rate of 99.8%.

• MLCC Lamination: The DMG25 servo electric cylinder (rated thrust 854N) enables lamination of over 1000 layers of ceramic sheets, reducing material loss rate from 3% to 1.5%.

2. Automotive Manufacturing

• Powertrain Assembly: The GTY8-L10 model (10mm lead) achieves ±0.02mm bearing press-fitting accuracy in transmission assembly, with a pressure control deviation of ≤5N.

• Robot 7th Axis for Welding: The DGTH5 servo electric cylinder (800mm stroke) expands the robot’s working range, enabling 3D trajectory welding of vehicle body welds with a path accuracy of ±0.1mm.

3. Medical Equipment

• Surgical Robot Positioning: The CHS2-S20 electric gripper (clamping force 20–124N) cooperates with a robotic arm to achieve precise control of minimally invasive surgical instruments, with a repeat position accuracy of ±0.01mm.

• Imaging Equipment Movement: The CGTH4 stepper electric cylinder (600mm stroke) drives CT scan tables, with a stable speed controlled at 1–50mm/s to meet dynamic imaging requirements.

V. Selection Process and Verification

1. Preliminary Screening

• Load and Stroke: Input parameters via the Toyo selection manual or online tools (e.g., TOYO Robot official website) to generate a list of candidate models.

• Environmental Adaptation: Further filter based on temperature, protection level, and cleanliness requirements.

2. Performance Verification

• Simulation Testing: Use TOYO-Single software for motion simulation to verify whether speed, acceleration, and torque meet requirements.

• Sample Testing: Apply for samples for actual working condition testing, focusing on verifying repeat positioning accuracy, noise level, and long-term operation stability.

3. Technical Support

• Localized Services: Obtain technical solutions through authorized distributors (e.g., Shenzhen Huiji Shidai Technology, Shanghai Yufei Electromechanical) and enjoy after-sales support with a response time of within 2 hours.

• Training and Documentation: Attend Toyo’s official training courses and obtain materials such as Servo Electric Cylinder Selection Guide and TC100E Controller Operation Manual.

VI. Maintenance and Cost Optimization

1. Preventive Maintenance

• Lubrication Cycle: Supplement ISO VG 32 grease every 50km of travel to extend the screw service life to over 2500 hours.

• Vibration Detection: Quarterly vibration testing (threshold >1.5mm/s) to detect guideway wear or bearing looseness in a timely manner.

2. Cost Control

• Modular Design: Select standardized modules (e.g., GTY series) to reduce customization costs. A 15–20% discount is available for bulk purchases.

• Energy Efficiency Optimization: Servo electric cylinders save 60% more energy than hydraulic cylinders and 40% more than pneumatic cylinders, significantly reducing electricity costs during long-term operation.
