MY1B20-400: Mechanical Coupling Rodless Cylinder, the Space Optimization Expert for Industrial Automation
2025-12-25
The MY1B20-400 is a mechanical coupling rodless cylinder produced by SMC of Japan, belonging to the MY1B series basic type. Utilizing mechanical coupling technology, it achieves reciprocating motion through the mechanical connection of the slider and piston. With its space-saving design, long stroke, and high precision, it is an ideal choice for industrial automation.Core Product Advantages
- Space-Saving Design Compared to standard cylinders, it reduces installation space by half for the same stroke, achieving approximately 44% axial space savings, making it particularly suitable for automated equipment with limited space.
- Long Stroke Configuration Features a 400mm stroke. Thanks to its rodless design, maximum stroke can reach 3m (for bore sizes ≥40mm), meeting long-stroke application needs. The bore-to-stroke ratio can reach approximately 1/100, far exceeding the 1/15 limit of standard cylinders.
- High-Precision Control Employs a wedge cam mechanism, achieving repeatability of ±0.01mm. Piston speed ranges from 100-1000mm/s (or 100-1500mm/s with a cushion), satisfying the demands of precision assembly and positioning.
- No Anti-Rotation Mechanism Required The mechanical structure design eliminates the need for an anti-rotation mechanism, simplifying installation and maintenance processes.

Product Features
- Lightweight Design: Through modifications to the main body and internal structure, weight is reduced by 10%. Overall length is shortened by 21.7mm and thickness decreased by 7.6mm. The slim design reduces generated moment.
- Cushioning Configuration: Equipped with a hydraulic damper for light loads + adjustment screw, with an adjustment range of -6~0mm, effectively absorbing impact force and protecting equipment.
- Magnetic Switch Compatibility: Can be directly equipped with small magnetic switches for position detection and stroke control, enhancing equipment intelligence.
- Multiple Specifications Available: Available in various bore sizes (10~100mm) and strokes (100~2000mm) to meet different load and application requirements.
Usage Precautions
- Installation Requirements: Ensure the mounting surface is flat during installation to prevent premature seal damage. In environments with high dust, water droplets, or oil droplets, the piston rod side should be equipped with a bellows boot.
- Air Quality: Use clean, dry compressed air. The air must not contain synthetic oil with organic solvents, salt, corrosive gases, etc., to prevent malfunction of the cylinder and valves.
- Load Control: Operate with a load ratio of 50% or less of the theoretical output. A load ratio exceeding 50% of the theoretical output may cause lock-up.
- Speed Control: Use a speed controller with meter-out flow control to avoid impact damage caused by excessive speed.
- Regular Maintenance: Regularly inspect seals and clean air lines to ensure long-term, stable operation of the cylinder.
