SMC Pneumatic Guided Cylinder 25mm Bore Double Acting Aluminium Body CDQMB25-20

The SMC CDQMB25-20 is a pneumatic guided cylinder engineered for compact and robust linear actuation in industrial automation, machine construction, and fluid power systems. With a bore diameter of 25mm and double acting operation, this cylinder delivers precise and reliable movements for machinery requiring efficient actuation.

Constructed with a hard anodized aluminium alloy body and rubber cushioning, the CDQMB25-20 offers long-lasting durability and resistance to environmental wear, making it ideal for demanding conditions. Its slide bearing guide design provides superior lateral load resistance, ensuring the cylinder can accommodate direct loads and maintain alignment during operations. This capability allows the cylinder to handle applications that demand stability and precision, outperforming standard CQ series cylinders in load resistance.

The cylinder operates up to 1 MPa maximum pressure, with a standard stroke length of 20mm. Its compact build - measuring just 65.5mm in length, 40mm in height and width, and weighing 180 grams - makes it suitable for confined spaces and installations where reduced size and weight are critical. The through hole mounting type simplifies integration with systems compatible with SMC CQS and CQ2 series cylinders, supporting versatility in mounting and replacement.

The single rod, double acting configuration allows for controlled movement in both directions, powered by clean compressed air. Operating temperature spans from -10°C to 70°C, ensuring performance stability across various plant environments and climates. Rubber cushioning built into the cylinder dampens end-of-stroke impacts, while the magnetic piston capability supports position detection in automated setups.

Applications encompass factory automation, materials handling, process engineering, packaging machines, fluid power assemblies, and other scenarios where guided pneumatic motion is required. The cylinder’s aluminium alloy body not only reduces weight but also provides superior corrosion resistance and lifespan compared to traditional steel-bodied cylinders.

Compact guided cylinders such as the CDQMB25-20 are critical in mechanical and hydraulic engineering for applications requiring precise actuation, stability under lateral loads, and space-efficient solutions.
