SMC Compact Pneumatic Guided Cylinder, 12mm Bore, 5mm Stroke, Double Acting, CQM Series, Aluminium Body, Through CDQMB12-5

The SMC CDQMB12-5 is a compact pneumatic guided cylinder engineered for high precision motion applications in industrial automation and machine building. This model features a 12 mm bore and 5 mm stroke, delivering accurate, linear double-acting motion while occupying minimal space in mechanical assemblies. The robust body construction is formed from hard anodized aluminium alloy, offering both strength and excellent corrosion resistance for extended service life, even in demanding industrial environments.

The CDQMB12-5 uses a slide bearing guide that enables lateral load resistance superior to standard compact cylinders, making it capable of handling direct and off-axis loads reliably. The cylinder’s through-hole mounting design provides secure, easy fixation, facilitating straightforward integration into automation equipment, packaging lines, or pick-and-place units where installation space is restricted.

Performance is maintained under a maximum operating pressure of 1 MPa, permitting operation in a range of pneumatic systems with fast, repeatable action. A single rod configuration with a non-rotating feature ensures the load remains in a stable orientation throughout the actuation, ideal for processes requiring precise, consistent movement.

A rubber cushioning system protects internal components during cycle end positions, minimizing wear and noise, while the operating temperature capability from -10°C up to 70°C accommodates a broad range of manufacturing conditions. The compact geometry, measuring 36.5 mm in length, 25 mm in width, and 25 mm in height, supports deployment in densely packed control cabinets or specialized machines.

Weighing just 44 g, this cylinder is well-suited for installations where low mass is critical. Typical applications include automated guided equipment, robotic arms, assembly stations, and small-scale pneumatic tooling in laboratory or production settings.

The SMC CDQMB12-5 Pneumatic Guided Cylinder is part of the CQM series and is recognized for compatibility with CQS and CQ2 series mounting options, offering versatility across a variety of system layouts. Its reliable operation and robust design make it a preferred choice for engineers and integrators aiming to maximize process efficiency and component longevity in industrial, manufacturing, and laboratory automation environments.
