Overview and Core Specifications
The Festo DSBC-63-500-PPVA-N3 is a double-acting pneumatic cylinder designed for linear actuation in industrial automation. With a 63 mm piston diameter and a 500 mm stroke, it delivers a theoretical force of 1870 N advancing and 1682 N retracting at 6 bar. The cylinder operates within a pressure range of 0.4 to 12 bar and is suitable for ambient temperatures from -20°C to 80°C. Its ISO 15552 compliance ensures metric mounting dimensions that align with widely used cylinder standards, simplifying integration into existing systems.
The unit features a high-alloy steel piston rod with an M16x1.5 external thread, providing robust performance and durability. The rod end is threaded for straightforward connection to tooling or loads. The cylinder's structural design includes a piston, piston rod, and profile barrel, all engineered for reliable operation in medium to heavy load applications.
Adjustable Cushioning for Controlled Motion
One of the key features of this model is its adjustable pneumatic cushioning at both ends. This system absorbs kinetic energy at the end of stroke, reducing impact noise and vibration. The cushioning length is 22 mm, and the impact energy in the end positions is rated at 1.3 J. This makes the DSBC-63-500-PPVA-N3 particularly suitable for high-speed cycles or applications where smooth deceleration is critical to protect the machine and workpiece. The adjustability allows engineers to fine-tune the cushioning effect based on actual load and speed conditions, optimizing performance without external shock absorbers.
Position Sensing and Control Integration
For precise position monitoring, the cylinder is equipped with sensor slots on three sides, enabling contactless sensing via proximity sensors. This capability supports automated control sequences where confirming the piston rod's position is necessary for safety or process accuracy. The integration of sensors is straightforward, allowing the cylinder to be incorporated into feedback loops for closed-loop control or simple end-position detection. This feature enhances system reliability by providing real-time status without mechanical wear on sensing components.
Materials and Environmental Suitability
The DSBC-63-500-PPVA-N3 is constructed with materials selected for durability and moderate corrosion resistance. The cylinder barrel is made of smooth-anodized wrought aluminum alloy, while the piston is of wrought aluminum alloy. The piston rod is high-alloy steel, and the cover is die-cast aluminum with a coating. Seals and wipers are made from TPE-U (PU) and TPE-E, offering good wear resistance. The corrosion resistance class is rated as 2, indicating suitability for moderate corrosion stress environments. Additionally, the cylinder is LABS (PWIS) conformant to VDMA24364-B1/B2-L, making it appropriate for use in paint shops or areas where silicone-free materials are required. All materials are RoHS-compliant, aligning with environmental standards.
Weight, Mounting, and Practical Considerations
Weighing 1774 g at zero stroke, with an additional 92 g per 10 mm of stroke, the cylinder offers a balance between robustness and manageability. The moving mass is 430 g at zero stroke, plus 25 g per 10 mm stroke, which is important for calculating dynamic loads and selecting appropriate guide systems. The cylinder can be mounted in any orientation, and mounting options include internal threads or accessories, providing flexibility in design. The pneumatic connection is G3/8, a common port size that simplifies piping. The operating medium is compressed air per ISO 8573-1:2010 [7:4:4], and oil lubrication is possible if required for further use. These specifications make the DSBC-63-500-PPVA-N3 a practical choice for engineers seeking a reliable, ISO-standard cylinder with adjustable cushioning and sensing capabilities for demanding automation tasks.
