Overview and Key Specifications
The Festo DSBC-100-80-D3-PPSA-N3 (manufacturer ID 8165697) is a double-acting pneumatic cylinder designed for applications that require reliable, precise linear motion. With a 100 mm piston diameter and an 80 mm stroke, this unit delivers theoretical forces of 4712 N advancing and 4418 N retracting at 6 bar. It conforms to ISO 15552, ensuring dimensional interchangeability with other standard cylinders. The cylinder features a profile barrel with piston rod at one end, and the piston rod end is an external thread (M20x1.5). The pneumatic connection is G1/2, and the operating pressure range is 0.4 to 12 bar.
The DSBC-100-80-D3-PPSA-N3 is built for flexibility in mounting—it can be mounted in any position, and the type of mounting is optional via internal thread or accessories. The ambient temperature range is -20°C to 80°C, making it suitable for a variety of industrial environments. The cylinder is RoHS-compliant and meets LABS (PWIS) conformity per VDMA24364-B1/B2-L, which is important for paint and adhesive applications.
Design and Construction for Durability
The cylinder's construction emphasizes corrosion resistance and longevity. It has a corrosion resistance class (CRC) of 2, indicating moderate corrosion stress capability. Key materials include a die-cast aluminum coated cover, a smooth-anodized wrought aluminum alloy barrel, a high-alloy steel piston rod, and a wrought aluminum alloy piston. The piston seal, rod wiper, and buffer seal are made of TPE-U (PU), while the cushion piston uses POM. The bearing is a metal polymer compound, and nuts and flange screws are galvanized steel. These material choices contribute to a robust design that can withstand demanding operating conditions.
The cylinder is designed for operation with compressed air as per ISO 8573-1:2010 [7:4:4]. Oil lubrication is possible but must be continued if used initially. The moving mass at 0 mm stroke is 1000 g, with an additional 39 g per 10 mm stroke. The basic weight is 3728 g, plus 152 g per 10 mm stroke, which is useful for calculating system dynamics and total weight.
Self-Adjusting Cushioning and Position Sensing
One of the standout features of the DSBC-100-80-D3-PPSA-N3 is its self-adjusting pneumatic end-position cushioning. This system automatically adapts to changing load and speed conditions, providing smooth deceleration at the end of stroke without manual adjustment. This reduces wear on the cylinder and the machine, and is particularly beneficial in applications requiring constant and smooth feed motions. The cushioning length is 31 mm, and the impact energy in the end positions is 2.5 J, ensuring controlled stopping even with moderate kinetic energy.
The D3 variant includes sensor slots on three sides of the profile barrel, allowing for flexible mounting of proximity sensors. This enables precise position sensing and feedback for control systems, which is critical in automated processes where exact piston position must be monitored. The cylinder is designed for proximity sensors, and the sensor slots facilitate easy installation and adjustment.
Application Considerations and Integration
Given its specifications, the DSBC-100-80-D3-PPSA-N3 is well-suited for a range of industrial automation tasks, including material handling, packaging, and assembly equipment. Its high force output and precise control make it ideal for clamping, pressing, or feeding operations. The self-adjusting cushioning simplifies setup and reduces commissioning time, as there is no need to tune cushioning screws for different loads.
When integrating this cylinder, engineers should consider the operating pressure and force requirements. The theoretical forces at 6 bar provide a baseline, but actual force will vary with pressure. The cylinder's mounting flexibility allows for adaptation to existing structures, and the ISO 15552 standard ensures compatibility with standard mounting accessories. The ambient temperature range and corrosion resistance class should be checked against the specific environment, especially if the cylinder will be exposed to moisture or chemicals.
For procurement teams, the DSBC-100-80-D3-PPSA-N3 offers a balance of performance and durability. The use of high-quality materials and the self-adjusting cushioning feature may reduce maintenance needs over the cylinder's lifetime. The RoHS compliance and LABS conformity also support use in industries with strict environmental and cleanliness standards.
Practical Benefits for Engineers and Buyers
From an engineering perspective, the DSBC-100-80-D3-PPSA-N3 simplifies design and installation. The sensor slots on three sides provide flexibility in sensor placement, and the self-adjusting cushioning eliminates the need for manual tuning. The cylinder's robust construction and corrosion resistance reduce the risk of premature failure, contributing to higher machine uptime.
For buyers, the cylinder's compliance with ISO 15552 and its modular design mean that spare parts and accessories are likely to be readily available. The detailed technical parameters, such as weight and moving mass, allow for accurate system calculations. While the initial cost may be higher than some alternatives, the potential for reduced maintenance and longer service life can offer a lower total cost of ownership.
In summary, the Festo DSBC-100-80-D3-PPSA-N3 is a versatile and reliable pneumatic cylinder that meets the demands of modern automation. Its combination of force, precision, and durability makes it a solid choice for engineers and procurement professionals seeking a high-quality linear actuator.
