CXSM Series Double Dual Shaft Rod Cylinders

Product Detailed Description：

Engineered for stability and precision, the CXSM Series Twin-Rod Cylinder utilizes two parallel piston rods to provide twice the thrust of a standard cylinder while ensuring superior resistance to side loads. The high-strength alloy body and integrated magnetic ring make it compatible with auto-switch sensors for seamless integration into smart factory systems.Whether you are upgrading an existing SMC-style system or building a new CNC machine, the CXSM series delivers the durability and smooth linear motion required for demanding industrial environments.

Product Feature：

1.Double Thrust Power: Dual piston rod design provides twice the output force of conventional cylinders.

2.High Non-Rotating Accuracy: Ensures precise linear motion with minimal deflection, perfect for high-accuracy positioning.

3.Integrated Guide Design: Built-in high-quality bearings provide excellent resistance to lateral loads and long service life.

4.Magnetic Ready: Standard built-in magnet for position sensing with auto-switches.

5.Compact & Space-Saving: Streamlined profile allows for installation in tight mechanical spaces without compromising performance.

6.Adjustable Stroke: Available with adjustable stroke options (rubber bumpers or shock absorbers) to minimize impact.

Application：

1.Pharmaceutical & Medical Lab Automation：

For the handling of reagents and test tubes, smooth and repeatable motion is required. CXSM cylinders are integrated into automated capping and decapping stations. The dual-rod design allows for the attachment of specialized grippers that can apply high torque to caps without twisting the cylinder's internal seals. Its compact, oil-free design is also compatible with the cleanroom standards required for pharmaceutical manufacturing.

2.High-Speed Packaging & Precision Labeling：

In labeling machinery, the application head must move in a perfectly linear path without any vibration or rotation. The CXSM cylinder drives the labeling stamp with absolute stability, ensuring that every label is applied precisely at the same angle, even at speeds of hundreds of cycles per minute. Additionally, its robust guide rods allow it to act as a "pusher" or "diverter" on conveyors, effortlessly handling the side impact of heavy boxes or bottles.

3.Precision Electronics & SMT Assembly：

In High-Density SMT production lines, the CXSM cylinder is the preferred choice for high-speed pick-and-place operations. Its dual-rod design ensures "Zero-Rotation," which is critical when handling microscopic components like SMD chips and sensors. Unlike single-rod cylinders that may slightly twist, the CXSM keeps the suction nozzle or gripper perfectly aligned, preventing component misalignment during high-speed placement or soldering processes.

Installation and Usage：

1.Alignment Check: Ensure the load is centered between the two rods as much as possible to maximize the lifespan of the guide bushings.

2.Piping Hygiene: Flush all air lines to remove debris before connecting to the cylinder ports to prevent seal damage.

3.Speed Regulation: Always use speed controllers (Flow Controls) to start the cylinder slowly, then adjust to the required speed to avoid internal impact damage.

4.Sensor Installation: Insert auto-switches into the body grooves and tighten the set screw. Ensure the sensor is positioned to trigger correctly at the end-of-stroke.

5.Bumper Adjustment: If using the adjustable stroke version, ensure the locking nut is tightened after setting the required travel distance.

FAQ

Q1.Is the CXSM cylinder a direct replacement for the SMC CXS series?

A1.Yes. Our CXSM series is designed to 1:1 technical and dimensional standards. The mounting holes, thread sizes, and performance curves match the SMC CXS series, allowing for a seamless drop-in replacement without modifying your machine.

Q2.What is the difference between the Basic Bushing and Ball Bearing versions?

A2.The Basic Bushing (Standard) is ideal for vertical movements and general pushing. The Ball Bearing version (CXSML) offers lower friction and is better suited for horizontal applications with significant lateral loads.

Q3.Can I adjust the stroke of the CXSM cylinder?

A3.Standard models have a fixed stroke. However, we offer an "Adjustable Stroke" version (suffix -AS, -BS, or -CS) which allows you to reduce the extension stroke by 0-5mm or more using adjustment bolts.

Q4.Does the dual-rod design mean it uses twice the air volume?

A4.No. While it provides double the force, the air consumption is proportional to the combined area of the two pistons. It is highly efficient for applications requiring high force in a narrow space.

Q5.What auto-switches are compatible with this cylinder?

A5.The CXSM body features integrated grooves compatible with standard D-A93 (Reed), D-M9B (PNP), and D-M9N (NPN) sensors. These sensors are available in our store and can be pre-installed.

Q6. How much side load can the CXSM handle before bending?

A6. The dual-rod design is highly resistant to torque. For example, a 20mm bore CXSM can handle significantly more lateral force than a standard 20mm single-rod cylinder. Please refer to our "Allowable Lateral Load" chart in the full catalog for specific Newton-meter (N·m) limits.

Q7.Is lubrication required during operation?

A7.The CXSM is pre-lubricated with high-quality synthetic grease and is designed for "non-lube" service. If you choose to use an inline lubricator, you must continue using it to prevent the original grease from washing away.

Q8. Can this cylinder be used in high-temperature environments?

A8. The standard operating range is up to 60°C (140°F). For high-heat applications (up to 120°C/248°F), please contact us for custom Viton (FKM) seals to ensure long-term reliability.
