OEM Factory Direct CDQSB Series Compact Pneumatic Cylinder Manufacturer Double-Acting Single Rod Air Cylinder Compatible With SMC

Product Detailed Description:

The CDQSB Series (Compact Short-Stroke Cylinder) is the ultimate solution for space-critical automation. By significantly reducing the overall body length compared to traditional actuators, the CDQSB series provides high force output within a minimalist footprint.

Each cylinder is constructed from premium hard-anodized aluminum alloy, ensuring exceptional wear resistance and a long service life. The integrated magnetic piston is a standard feature, allowing for easy mounting of proximity sensors on multiple sides of the square body. With high-quality internal seals and a precision-machined piston rod, this cylinder delivers smooth, reliable linear motion for millions of maintenance-free cycles.

Product Advantages

• Ultra-Compact Footprint — Short body length fits tight machine envelopes where standard ISO cylinders cannot. Ideal for dense multi-station layouts.
• Aluminum Alloy Body — Hard-anodized aluminum barrel and end caps for corrosion resistance and low weight. Reduces moving mass on high-cycle applications.
• SMC CQS/CDQS Series Compatible — Same mounting dimensions and port positions as industry-standard SMC compact cylinders. Drop-in replacement — no redesign needed.
• Long Stroke Capability — Up to 300mm stroke in bore sizes 12–25mm, uncommon in compact-form cylinders at this price point.
• Double Acting, Rubber Bumper Cushion — Reliable bidirectional force with built-in end-of-stroke cushioning. Smooth deceleration without external shock absorbers.
• Magnetic Piston (Standard) — Auto switch ready. Mount reed or solid-state sensors on 3 sides (ø12–16) or 4 sides (ø20–25) for position feedback.
• Low Minimum Operating Pressure — Starts from 0.03 MPa. Works reliably in low-pressure branches and vacuum-assisted circuits.
• Wide Speed Range — 50–500 mm/s piston speed. Adjustable via flow control valves for precision applications.
• Direct Factory Supply — 16 years pneumatic specialization, 100+ CNC centers, CE certified, shipped to 120+ countries.

Application：

• Electronic Component Assembly ：

In the high-precision SMT (Surface Mount Technology) sector, the CDQSB is essential for PCB clamping and component positioning. Its micro-scale footprint allows it to fit into the narrow gaps of pick-and-place machines. The built-in magnet ensures the control system receives immediate feedback when the cylinder reaches its stroke end, preventing mechanical interference and protecting sensitive electronic substrates from damage.

• Automotive Parts Handling & Inspection：

For automotive manufacturing, the CDQSB serves as a precision stopper and pusher on high-speed conveyor lines. It is frequently used in automated QC stations to move small parts into the field of view of inspection cameras. Its ability to handle high-frequency cycles makes it reliable for 24/7 automotive production environments, where even a small delay in component sorting can halt the entire assembly line.

• Automated Packaging & Labeling ：

In the packaging industry, CDQSB cylinders drive micro-labeling heads and diverting gates. Because they can be mounted in tight vertical or horizontal orientations, they are perfect for folding box flaps or pushing small containers onto different conveyor paths. The magnetic sensing capability allows for perfect synchronization between the cylinder stroke and the labeling software, ensuring labels are applied accurately every time.

• Pharmaceutical Packaging & Medical Automation ：

In cleanroom environments, the CDQSB drives micro-filling valves and capping mechanisms. Because it can be mounted in tight vertical or horizontal orientations, it is perfect for compact laboratory equipment or pill-bottling machines. The hard-anodized body provides the necessary cleanliness and corrosion resistance for pharmaceutical standards, while the precise stroke control ensures consistent dosing and packaging results.

Installation and Usage：

• Mounting: Use the through-holes for direct mounting. Ensure the surface is flat to prevent internal stress on the cylinder body.
• Sensor Setup: Slide T-slot auto-switches into the grooves and secure them at the desired sensing position.
• Speed Control: Always use flow control valves to regulate speed and minimize internal impact at high frequencies.
• Air Quality: Use filtered, dry air to maintain the integrity of the seals and internal grease.
• Alignment: Avoid side-loading the piston rod; ensure the load is axially aligned for optimal performance.

FAQ

Q1.Is the CDQSB series interchangeable with other standard compact cylinders?

A1.Yes, the CDQSB series is manufactured to international industrial standards, making it a direct drop-in replacement for most square-body compact cylinders on the market.

Q2.Does this model always come with a magnetic piston?

A2.Yes, the "D" in CDQSB represents the built-in magnetic ring. This allows for position sensing without any external modifications.

Q3.Can I get this cylinder with a male rod-end thread?

A3.The standard version has a female thread. However, we can provide male thread versions (Suffix -M) or custom rod-end adapters upon request.

Q4. Which auto-switches are compatible with the CDQSB?

A4. It is compatible with all standard T-slot sensors, including popular Reed and Solid State (PNP/NPN) models.

Q5. What is the benefit of the square body?

A5.The square body design is space-efficient and provides mounting surfaces on multiple sides, which is much more versatile than round-body cylinders.

Q6. What are the available bore sizes?

A6. We offer a full range from 12mm up to 100mm to suit various force requirements.

Q7. Is it suitable for high-temperature use?

A7.The standard rating is 60°C. For higher temperatures, we offer custom versions with Viton (FKM) seals rated up to 150°C.

Q8. Does it require additional lubrication?

A8. The CDQSB is pre-lubricated for life with high-quality synthetic grease. No additional lubrication is required under standard operating conditions.

Q9.What is the minimum maintenance required?

A9.CDQSB compact cylinders are pre-lubricated and designed for oil-free operation with filtered, non-lubricated compressed air.

Daily / Weekly: Visual check — no air leaks at ports or rod seal, rod surface clean and undamaged.

Monthly: Verify auto switch positioning if used; check mounting bolts are tight.

Every 1 million cycles or 6 months: Inspect rod seal for wear; replace if leakage observed.

Every 3 million cycles: Replace internal piston seal and wear ring as preventive maintenance.
