Overview and Key Specifications
The Festo DSBC-125-200-D3-PPSA-N3 (manufacturer ID 8165667) is a double-acting pneumatic cylinder designed for applications that require reliable linear motion under moderate corrosion stress. With a 125 mm piston diameter and a 200 mm stroke, this cylinder delivers a theoretical force of 7363 N advancing and 6881 N retracting at 6 bar. Its piston rod thread is M27x2, and the pneumatic connection is G1/2. The cylinder conforms to ISO 15552, ensuring interchangeability with other standard cylinders. The design includes a profile barrel, piston, and piston rod, with the piston rod ending in an external thread. Position sensing is supported for proximity sensors, making it suitable for automated control systems.
Performance and Cushioning
The DSBC-125-200-D3-PPSA-N3 features self-adjusting pneumatic end-position cushioning, which automatically adapts to varying load and speed conditions. This cushioning system reduces impact energy at the end positions (rated at 3.3 J) and extends the service life of the cylinder by minimizing mechanical stress. The cushioning length is 45 mm, providing ample deceleration for the moving mass. The cylinder operates within an ambient temperature range of -20°C to 80°C and can handle operating pressures from 0.2 bar to 10 bar. The moving mass at 0 mm stroke is 2245 g, with an additional 63 g per 10 mm of stroke, while the basic weight is 6768 g plus 247 g per 10 mm stroke. These figures are essential for calculating dynamic loads and selecting appropriate mounting structures.
Materials and Corrosion Resistance
This cylinder is built with materials that meet corrosion resistance class 2 (moderate corrosion stress) according to Festo standards. The cover is made of coated die-cast aluminum, the cylinder barrel is smooth-anodized wrought aluminum alloy, and the piston rod is high-alloy steel. Seals and wipers are primarily TPE-U (PU) and TPE-E, ensuring durability and low friction. The piston is wrought aluminum alloy, and the cushion piston is POM. All materials are RoHS-compliant, and the cylinder conforms to LABS (PWIS) VDMA24364-B1/B2-L, making it suitable for use in paint and coating environments where silicone-free components are required. The external surfaces are designed to withstand moderate industrial atmospheres, but for harsher conditions, additional protection may be necessary.
Mounting and Integration Flexibility
The DSBC-125-200-D3-PPSA-N3 can be mounted in any position, offering maximum flexibility in system design. It can be mounted using internal threads or with accessories, allowing integration into various machine configurations. The cylinder is double-acting, meaning it uses air pressure for both extension and retraction, providing controlled motion in both directions. The operating medium is compressed air as per ISO 8573-1:2010 [7:4:4], and oil lubrication is possible if required for subsequent use. This flexibility makes the cylinder suitable for a wide range of applications, from assembly lines to material handling equipment.
Application Considerations
When selecting this cylinder, engineers should consider the required force, stroke length, and mounting constraints. The theoretical forces at 6 bar are substantial, making this cylinder suitable for pushing, pulling, or lifting moderate loads. The self-adjusting cushioning simplifies setup, as it eliminates the need for manual cushioning adjustment. The cylinder's conformity to ISO 15552 ensures compatibility with standard mounting accessories and simplifies replacement in existing systems. For procurement teams, the DSBC-125-200-D3-PPSA-N3 offers a balance of performance, durability, and ease of integration, backed by Festo's engineering reputation. Always verify that the operating pressure, temperature, and media conditions match your application requirements to ensure optimal performance and longevity.
