SMC CQ2B40-15DZ Compact Cylinder (CQ2B4015DZ)
1. Product Overview
The SMC CQ2B40-15DZ (also designated as CQ2B4015DZ) is a high-performance compact cylinder from SMC’s renowned CQ2 series, engineered for space-constrained industrial automation scenarios. As a double-acting thin-type cylinder, it features a 40 mm bore diameter and 15 mm stroke length, delivering balanced thrust and pull forces for light to medium-duty tasks such as precision clamping, component pushing, workpiece positioning, and small-part assembly. Its space-saving slim design, combined with versatile mounting capabilities and compatibility with multi-surface magnetic switches, makes it ideal for electronic manufacturing, medical equipment, automated instrumentation, and packaging systems where installation space is at a premium. Adhering to SMC’s strict quality standards, the CQ2B40-15DZ ensures reliable long-term performance, low operational noise, and seamless integration with standard pneumatic control systems.
2. Main Functions
|
Function
|
Detailed Description
|
|---|---|
|
Double-Acting Linear Actuation
|
Converts pneumatic pressure into bidirectional linear motion (extension and retraction) with uniform force distribution, supporting automated cycle operations via solenoid valves and PLC control systems.
|
|
Built-In Cushioning
|
Equipped with non-adjustable pad cushions at both rod and cap ends to absorb impact, reduce operational noise, and prevent component damage during short-stroke stops.
|
|
Magnetic Position Sensing
|
Integrated magnetic ring in the piston (designated by “D” in the model) enables installation of magnetic proximity sensors, with four mounting surfaces available for sensor placement (a key advantage of ø40 models), providing real-time position feedback for closed-loop control.
|
|
Multi-Orientation Mounting
|
Supports front, rear, and side mounting via standardized holes, adapting to horizontal, vertical, and inclined installation orientations in confined spaces.
|
|
Short-Stroke Precision
|
Optimized for 15 mm short stroke, ensuring high positioning accuracy and stable motion, with built-in cushioning to mitigate impact, suitable for tasks requiring precise linear displacement with tight tolerances.
|
3. Technical Features
-
Space-Saving Design: Thin-type structure with shortened overall length and reduced radial dimensions, occupying significantly less space than standard cylinders. Compared to previous generations, it offers weight reduction and volume optimization, ideal for compact automation setups.
-
Durable Construction: Cylinder barrel made of hard-anodized aluminum alloy, ensuring wear resistance and corrosion resistance, while the stainless steel piston rod (SUS304) with chrome plating enhances durability.
-
Reliable Sealing System: Double NBR rubber seals prevent air leakage, maintaining stable pressure and consistent performance even at maximum operating pressure, with optional Viton seals for high-temperature applications.
-
Broad Operating Range: Functions reliably at 0.15–1.0 MPa air pressure and -10°C to 60°C ambient temperature, adapting to typical industrial working conditions with relative humidity ≤85%.
-
Oil-Free Operation: Designed for maintenance-free, oil-free lubrication, reducing operational costs and making it suitable for clean environments like electronic component assembly.
-
Versatile Compatibility: Compatible with SMC’s full range of pneumatic fittings, rod-end accessories (including single and double elbow joints), and mounting hardware, ensuring easy configuration and replacement in existing systems.
