Overview and Key Specifications
The Festo DSBC-63-400-D3-PPVA-N3 is a double-acting pneumatic cylinder with a 63 mm piston diameter and a 400 mm stroke. It conforms to ISO 15552, ensuring dimensional interchangeability with other standard cylinders. The cylinder features a profile barrel design with a piston rod at one end, and the piston rod end is an external thread (M16x1.5). The pneumatic connection is G3/8, and the operating pressure range is 0.4 to 12 bar. At 6 bar, the theoretical advancing force is 1870 N, and the retracting force is 1682 N. The cylinder is designed for use with compressed air per ISO 8573-1:2010 [7:4:4] and can be operated with oil lubrication if required for further use.
Adjustable Cushioning and End-Position Control
The DSBC-63-400-D3-PPVA-N3 is equipped with pneumatic cushioning that is adjustable at both ends. This feature allows engineers to fine-tune the deceleration of the piston as it approaches the end positions, reducing impact energy and mechanical stress. The cushioning length is 22 mm, and the impact energy in the end positions is rated at 1.3 J. By adjusting the cushioning, you can minimize noise, vibration, and wear on the cylinder and connected components, which is particularly valuable in high-cycle applications or when handling delicate workpieces.
Position Sensing and Control Integration
This model includes the D3 feature, which provides sensor slots on three sides of the cylinder barrel. These slots are designed for proximity sensors, enabling precise piston position detection. With sensors mounted on multiple sides, you have flexibility in sensor placement, making it easier to integrate the cylinder into existing control systems. This capability supports accurate positioning and sequencing in automated processes, such as clamping, feeding, or indexing operations. The ability to sense position reliably is essential for applications that require repeatable motion and quality assurance.
Corrosion Resistance and Material Quality
The cylinder has a corrosion resistance class (CRC) of 2, indicating moderate corrosion stress capability. This makes it suitable for environments with occasional exposure to moisture or mild contaminants, such as in typical industrial settings. The materials used are RoHS-compliant and include a die-cast aluminum coated cover, a smooth-anodized wrought aluminum alloy barrel, a high-alloy steel piston rod, and a metal polymer compound bearing. These materials contribute to durability and long service life. The piston seals, rod wiper, and buffer seals are made of TPE-U(PU), while the cushion piston is made of POM, ensuring reliable sealing and wear resistance.
Mounting Flexibility and Weight Considerations
The DSBC-63-400-D3-PPVA-N3 can be mounted in any position, offering versatility in system design. It can be mounted using internal threads or with accessories, allowing for various mounting configurations such as foot, flange, or trunnion mounts. This flexibility is particularly useful for decentralized use in larger systems where space constraints or orientation requirements exist. When planning your system, note the weight characteristics: the basic weight with 0 mm stroke is 1774 g, and each additional 10 mm of stroke adds 92 g. The moving mass at 0 mm stroke is 430 g, with an additional 25 g per 10 mm stroke. These values are important for calculating dynamic loads and selecting appropriate guides or supports.
