SMC Cylinder CDQ2 Series CDQ2B12-5D Double Acting, Single Rod

This product boasts a slim profile, making it an ideal choice for applications where space is limited. For the same bore size, its overall dimensions—particularly the width and height—are significantly smaller compared to many conventional cylinders. This compact form factor enhances the integration flexibility within tight spaces.

The lightweight construction is achieved through the use of aluminum alloy for the main components. This not only reduces the overall weight of the cylinder but also contributes to the general trend of equipment lightweighting, improving ease of handling and installation.

The cylinder body includes specially designed mounting grooves: two on each side for smaller bore sizes and four on each side for larger bore sizes. These grooves allow the seamless embedding of compact magnetic switches, such as those from the D-M9 series. Once installed, these switches sit flush with the cylinder surface, saving space and minimizing the risk of damage from collisions.

In addition to the standard through-hole mounting (basic type), this cylinder supports a variety of optional accessories like foot mounts and flanges. This versatility enables it to meet diverse installation requirements across different applications.

The cylinder operates reliably within a pressure range of 0.07 MPa to 1.0 MPa and can function effectively in temperatures ranging from -10°C to +70°C. These operating conditions ensure consistent performance in a wide variety of environments.

Factory pre-lubrication eliminates the need for additional lubrication during regular operation under standard air conditions. This feature minimizes maintenance efforts and downtime, making the cylinder highly convenient to use.

Depending on the specific model, a range of cushioning options is available. These include rubber cushioning and adjustable air cushioning, which help achieve smooth stopping tailored to varying loads and speeds, enhancing both safety and performance.

The CDQ2B series is renowned for its compact size and reliable performance, making it an ideal choice in automation environments where space is limited. Its design ensures efficient operation without compromising on durability, which is why it has found widespread use across various industries.

Electronics & Semiconductor Manufacturing: The CDQ2B actuators serve crucial roles such as part transfer, clamping, and precise positioning in processes like circuit board fabrication, chip packaging, and high-precision inspection machinery.

Small Automation Equipment: These actuators are widely implemented as driving components in assembly machines, packaging equipment, and material handling manipulators, enabling smooth and accurate movements.

Medical Devices & Instruments: Thanks to their clean operation and compact design, CDQ2B actuators are well-suited for medical applications including laboratory automation devices and analytical instruments where space and contamination control are critical.

When choosing a CDQ2B series actuator, several key parameters should be taken into account. The bore size, which directly influences the output force, is a major factor—with common sizes including Φ12, Φ16, and Φ20. Additionally, the stroke length determines how far the actuator can travel, impacting its suitability for specific tasks.

The type of action mechanism is another important consideration. Depending on the application, one can opt for a double-acting actuator, which is pneumatically powered in both directions, or a single-acting version that uses a spring to return the piston.

Furthermore, it is essential to assess whether adjustable cushioning is necessary to accommodate varying loads and speeds smoothly. In environments where side loads are encountered, selecting a guided actuator variant, such as the CDQ2B/W series, can enhance durability and extend service life.
