1. Electronics and Semiconductor Manufacturing：
With ultra-slim bore sizes ranging from 6mm to 16mm, this series facilitates high-density mounting in robotic grippers and PCB assembly lines. It is an essential component for delicate pick-and-place operations, where millimeter-level accuracy and a minimal footprint are critical for handling sensitive micro-components efficiently without damaging fragile parts.
2. Medical and Laboratory Automation：
The SS304 stainless steel construction provides superior corrosion resistance and meets strict hygiene standards required for cleanroom environments. This makes it ideal for diagnostic equipment, reagent sampling systems, and automated liquid handling. Its reliable magnetic-sensing capabilities ensure consistent, high-precision performance in critical medical diagnostic workflows.
3. High-Speed Packaging and Sorting：
Modern packaging systems leverage the cylinder’s low-friction seals and rapid response times. The CDJ2D excels in repetitive labeling, sorting, and orientation tasks. Its durable design and integrated rubber bumpers minimize impact stress, ensuring long-term operational efficiency in compact, high-throughput environments where space optimization is paramount.
Installation and Usage：
1. Alignment: Use the integrated M5 ports for air connection. Ensure the load is strictly axial to avoid bending moments on the miniature piston rod.
2. Mounting Options: Compatible with Basic (B), Foot (L), Flange (F), and Double Clevis (D) mountings. Refer to the dimension table (Z+Stroke) for precise layout.
3. Speed Regulation: Always use speed controllers (flow control valves) at the ports to prevent the piston from striking the end covers too forcefully, as this series uses rubber bumpers.
4. Magnetic Sensors: Slide auto-switches into the mounting rail/band to detect the piston's magnet for automated sequence control.
FAQ
Q1. What is the maximum stroke for the 6mm bore CDJ2D?
A1. Standard strokes go up to 60mm for the 6mm bore, while 10mm and 16mm bores can support longer strokes up to 200mm.
Q2. Does CDJ2D come with the magnet included?
A2. Yes, the "CDJ2" designation indicates it includes a built-in magnetic ring. The "CJ2" version is the non-magnetic equivalent.
Q3. Can this cylinder handle high-pressure environments?
A3. The maximum working pressure is 0.7 MPa. It has been proof-tested at 1.05 MPa to ensure safety under intermittent surges.
Q4.Is the piston rod stainless steel as well?
A4.Standard models feature high-carbon steel rods with hard chrome plating. Stainless steel rods (SUS304) can be customized for food-grade or high-corrosion apps.
Q5. What type of air fitting do I need?
A5.All bore sizes (6, 10, 16) in this series use standard M5 × 0.8 threaded ports.
Q6.What does the "D" in CDJ2D stand for?
A6. According to the order code logic, "D" represents the Double Acting mode. We also offer "S" (Single acting pre-shrink) and "T" (Single acting pre-extend) variants.
Q7. Is lubrication required during operation?
A7.This series is designed for "non-lube" operation as it is pre-greased. If you use a lubricator, ensure it remains in use throughout the life of the cylinder.
Q8. Are the dimensions 100% identical to the SMC CJ2 series?
A8.Yes, our CDJ2 series follows the same mounting dimensions (A, B, H, Z+Stroke), allowing for direct drop-in replacement.
