Application-Specific Performance for Medium to Heavy Loads
The Festo DSBC-40-500-PPVA-N3 (MPN 8165584) is a double-acting pneumatic cylinder engineered for linear motion in automation systems that require reliable force delivery and controlled deceleration. With a 40 mm piston diameter and a 500 mm stroke, it delivers a theoretical advancing force of 754 N and a retracting force of 633 N at 6 bar. This makes it suitable for medium to heavy load applications, such as clamping, pressing, or material handling, where consistent force output is critical. The cylinder operates within an ambient temperature range of -20°C to 80°C and accepts compressed air per ISO 8573-1:2010 [7:4:4], with optional oil lubrication for extended use.
Precision Cushioning and Smooth Operation
One of the standout features is the adjustable pneumatic cushioning at both ends, which absorbs impact energy in the end positions—rated at 0.7 J with a cushioning length of 19 mm. This reduces noise and vibration, protecting both the cylinder and the connected machinery from shock loads. For high-speed applications or those with moving masses, this cushioning allows engineers to fine-tune deceleration, minimizing wear and extending service life. The high-alloy steel piston rod further enhances durability, providing excellent running performance even under heavy loads, while the overall design keeps weight low—basic weight is 768 g with an additional 49 g per 10 mm stroke.
Integration Flexibility with ISO 15552 and Position Sensing
The DSBC-40-500-PPVA-N3 conforms to ISO 15552, ensuring metric mounting dimensions that are interchangeable with other standard cylinders. This simplifies retrofitting and reduces engineering time when integrating into existing systems. The cylinder features a magnetic piston for contactless position sensing via proximity sensors, enabling precise monitoring and control of the piston position without physical contact. This is particularly valuable in automated processes where accurate stroke end detection or mid-stroke positioning is required. The mounting position is any, and the cylinder can be mounted using internal threads or accessories, offering flexibility in design.
Material and Environmental Considerations
Constructed with a smooth-anodized wrought aluminum alloy barrel and die-cast aluminum coated covers, the cylinder balances strength with corrosion resistance. It meets corrosion resistance class 2 (moderate corrosion stress) and is LABS (PWIS) conformant to VDMA24364-B1/B2-L, making it suitable for use in paint and coating environments where silicone-free materials are required. All materials are RoHS-compliant, and seals are made from TPE-U(PU) and TPE-E, ensuring compatibility with standard industrial lubricants and media.
Selection and Sizing Guidance
When specifying this cylinder, consider the moving mass and stroke length. The moving mass at 0 mm stroke is 205 g, with an additional 16 g per 10 mm stroke. For a 500 mm stroke, this adds 800 g, bringing the total moving mass to approximately 1005 g. This factor is critical for calculating dynamic loads and selecting appropriate cushioning settings. The operating pressure range is 0.6 to 12 bar, providing flexibility for various supply pressures. The pneumatic connection is G1/4, and the piston rod thread is M12x1.25 with an external thread end. These parameters ensure compatibility with standard fittings and tooling.
For procurement and engineering teams, the DSBC-40-500-PPVA-N3 offers a balance of performance, durability, and standardization. Its adjustable cushioning and position sensing capabilities make it a practical choice for applications demanding smooth, controlled motion and precise feedback. Always verify that the operating conditions—such as pressure, temperature, and media quality—align with the specified limits to ensure optimal performance and longevity.
