Overview and Key Specifications
The Festo DSBC-32-500-D3-PPSA-N3 (MPN: 8165461) is a double-acting pneumatic cylinder designed for linear motion in industrial automation. With a 32 mm piston diameter and a 500 mm stroke, it delivers a theoretical force of 483 N advancing and 415 N retracting at 6 bar. The cylinder conforms to ISO 15552, ensuring standard metric mounting dimensions and interchangeability with other ISO-compliant cylinders. Its compact profile barrel, made of smooth-anodized wrought aluminum alloy, contributes to a low overall weight while maintaining durability.
The piston rod is manufactured from high-alloy steel with an external M10x1.25 thread, providing excellent running performance and long service life. The cylinder can be mounted in any position, offering flexibility in system design. Pneumatic connection is via G1/8 ports, and the operating pressure range is 0.8 to 12 bar, making it suitable for a wide variety of pneumatic circuits.
Cushioning and Impact Absorption
A standout feature of this model is its self-adjusting pneumatic end-position cushioning. Unlike manually adjustable cushions, this system automatically adapts to load and speed changes, simplifying setup and reducing maintenance time. The cushioning length is 17 mm, and the impact energy in the end positions is rated at 0.4 J, which helps protect the cylinder and connected equipment from shock and vibration. This makes the DSBC-32-500-D3-PPSA-N3 particularly effective for medium to heavy loads and high-speed applications where consistent deceleration is critical.
For engineers, this means fewer adjustments during commissioning and reliable operation even when cycle times or payloads vary. The self-adjusting cushioning also contributes to lower noise levels, improving workplace conditions in production environments.
Position Sensing and Control Integration
The cylinder is equipped with sensor slots on three sides, allowing for contactless position detection using proximity sensors. This capability is essential for precise control and monitoring in automated processes, enabling functions such as end-position confirmation, mid-stroke sensing, and sequence control. The slots are designed for easy sensor mounting and adjustment, reducing installation time. For procurement teams, this built-in sensing feature eliminates the need for external mounting brackets, simplifying the bill of materials and reducing inventory complexity.
Materials and Environmental Suitability
The DSBC-32-500-D3-PPSA-N3 is built with materials selected for performance and longevity. The piston rod is high-alloy steel, while the cylinder barrel is smooth-anodized wrought aluminum alloy, offering a good balance of strength and weight. Seals and wipers are made of TPE-U (PU) and TPE-E, providing reliable sealing over a wide temperature range. The cylinder is rated for ambient temperatures from -20°C to 80°C and has a corrosion resistance class (CRC) of 2, indicating moderate corrosion stress capability. It is also LABS (PWIS) conformant to VDMA24364-B1/B2-L, making it suitable for use in paint and coating applications where silicone-free materials are required.
All materials are RoHS-compliant, meeting environmental and regulatory standards. The cover is die-cast aluminum with a coating, and the piston is made of wrought aluminum alloy. These material choices contribute to a long service life even in demanding industrial settings.
Weight and Mounting Flexibility
Weighing only 480 g at zero stroke, with an additional 31 g per 10 mm of stroke, this cylinder is lightweight yet robust. The moving mass is 110 g at zero stroke, plus 9 g per 10 mm stroke, which helps in calculating dynamic loads and selecting appropriate control valves. The cylinder can be mounted using internal threads or with accessories, offering versatility in machine design. This flexibility is particularly valuable for retrofitting existing systems or standardizing new equipment across different lines.
For buyers and engineers, the combination of ISO 15552 compliance, self-adjusting cushioning, and position sensing makes the Festo DSBC-32-500-D3-PPSA-N3 a practical choice for a wide range of automation tasks, from material handling to packaging machinery. Its robust construction and thoughtful design details reduce downtime and maintenance, ultimately contributing to higher overall equipment effectiveness.
