Product Detailed Description：
The CY3R Series represents the pinnacle of space-saving pneumatic technology. As a Magnetically Coupled Rodless Cylinder, it eliminates the need for an external piston rod, reducing the required installation space by up to 50% compared to conventional cylinders.
The "R" in CY3R specifically denotes its Non-rotating design, featuring an integrated guide rail that ensures the slider remains perfectly oriented throughout the stroke without the need for external stabilizers. Built with a high-grade stainless steel barrel and powerful rare-earth magnets, this cylinder provides high holding force and smooth linear motion. Whether you are replacing SMC CY3R units or designing a new high-speed automation line, our factory-direct CY3R series delivers OEM-level performance with significantly lower acquisition costs.

Product Advantages
1. Non-rotating design — anti-rotation accuracy guaranteed by the guide, no external guide rail needed, simplifies design and saves cost.
2. Space saving up to ~50% — rodless structure: total length ≈ half the stroke of a rod cylinder of the same travel; perfect for compact machines.
3. No external leakage — magnetically coupled piston drives the external carriage through the sealed tube; clean and suitable for diverse environments.
4. Direct mount type — load mounts directly onto the carriage; low profile, high rigidity, easy to integrate.
5. Full bore range — Ø6 / 10 / 15 / 20 / 25 / 32 / 40 / 50 / 63 mm; standard strokes up to 1000 mm, longer strokes available on request.
6. Improved lubrication — lube retainer on the dust seal evenly distributes oil, lowers the minimum operating pressure and extends service life (Ø15–63).
7. Multiple guide options — choose the guide level that matches your required accuracy and allowable moment.
8. Ready for auto switches — magnetic switch rail / switches available; ideal for position feedback and PLC control.
9. SMC-compatible, fully interchangeable — same mounting dimensions and stroke range as SMC CY3R / CY3B series; drop-in replacement.
10. Factory direct OEM/ODM — competitive wholesale price, custom machining, fast lead time, stable quality.
Application：
1. Automated Conveying and Material Handling：
The rodless design is a game-changer for long-stroke transfer systems. By eliminating the protruding piston rod, the CY3R allows for efficient material movement in tight spaces where traditional cylinders cannot fit. It is widely used in logistics and warehouse automation for cross-conveyor transfers and high-speed pusher systems, offering a reliable, low-maintenance solution for continuous industrial use.
2. Electronics and Precision Assembly：
The non-rotating accuracy is vital for the electronics sector. In PCB handling and smartphone assembly lines, the payload must remain perfectly aligned. The CY3R’s integrated guide rail maintains orientation without extra stabilizers, making it perfect for delicate pick-and-place tasks. Its clean, leak-free magnetic coupling also makes it suitable for semi-conductor cleanroom environments.
3. Packaging and Printing Machinery：
In high-cycle packaging lines, the CY3R provides smooth linear motion for labeling, film-cutting, and capping. Its stainless steel construction resists the wear of rapid, repetitive cycles, while the compact design allows for multi-axis synchronization in complex machinery, maximizing throughput in high-density production environments.
Installation and Usage：
1. Pre-Installation Inspection: Verify that the total load remains within the rated magnetic holding force. Clean the stainless steel tube surface to remove debris or metallic particles that might obstruct slider movement.
2. Mounting Precautions: Align the load precisely with the cylinder axis. Mount the unit on a flat, level surface to prevent body distortion, ensuring the integrated guide rail operates smoothly without friction.
3. Air Supply & Regulation: Use 40μm filtered, dry compressed air. Always install flow control valves at the ports to regulate speed and prevent violent end-of-stroke impacts that could decouple the internal magnets.
4. Auto-Switch Adjustment: Slide sensors into the integrated rails and secure them at required positions. Ensure no strong external magnetic fields are nearby, as they can cause sensor errors or affect coupling stability.
5. Operation & Maintenance: Maintain piston speeds between 50-400mm/s. This pre-lubricated unit requires no additional oiling. Regularly inspect mounting bolts and air fittings for tightness to ensure safe, leak-free, and stable operation.
FAQ
Q1. Is the CY3R series fully interchangeable with the SMC brand?
A1. Absolutely. Our CY3R series is manufactured according to international mounting standards and is 100% interchangeable with the SMC CY3R series in terms of dimensions, port sizes, and performance specifications.
Q2. What is the maximum stroke length you can provide?
A2. While standard strokes go up to 1000mm, we can manufacture custom strokes up to 6000mm (for bore size 63mm) depending on your application needs. Please contact our support team for specific stroke feasibility.
Q3. What materials are used to ensure the magnetic holding force?
A3. We use high-performance rare-earth permanent magnets to ensure a strong and stable magnetic coupling. This prevents the slider from decoupling even under high speeds and heavy loads.
Q4.Can I mount auto-switches to these cylinders for position feedback?
A4.Yes. The CY3R series features integrated switch rails. You can easily mount D-A93 or D-Z73 type magnetic sensors (or equivalent) to achieve precise end-of-stroke or intermediate position detection.
Q5. Does the cylinder require lubrication during its service life?
A5. The CY3R series is designed for non-lube operation. It is pre-lubricated with high-grade grease during assembly. If you choose to use a lubricator, ensure it is maintained throughout the cylinder’s life.
Q6.Are you a trading company or a source factory?
A6. We are a professional source factory specializing in pneumatic components. By purchasing from us, you get direct-from-factory pricing, strict quality control, and professional technical support without any middleman markups.
Q7. Do you support OEM and ODM customization?
A7.Yes, we provide full OEM/ODM services. We can laser-mark your brand logo on the cylinders and customize specific stroke lengths or mounting configurations to meet your unique equipment requirements.
Q8. What is the standard lead time for shipping?
A8.For standard bore sizes and strokes, we maintain a deep stock and can ship within 3-5 business days. For large bulk orders or customized OEM products, the lead time typically ranges from 10-15 days.
Q9.How long is the service life?
A9.Dependent on load, speed and air quality; typically millions of cycles with proper filtration (5 μm filter recommended) and lubrication.
