Core Specifications and Design
The Festo DSBC-80-400-D3-PPSA-N3 is a double-acting pneumatic cylinder with an 80 mm piston diameter and a 400 mm stroke. It conforms to ISO 15552, ensuring dimensional interchangeability with other standards-based cylinders. The piston rod features an external M20x1.5 thread, and the cylinder has a G3/8 pneumatic connection. The unit operates within a pressure range of 0.4 to 12 bar and can be mounted in any position. Its structural design includes a piston, piston rod, and profile barrel, with a die-cast aluminum coated cover and a smooth-anodized wrought aluminum alloy barrel.
The cylinder is equipped with self-adjusting pneumatic end-position cushioning, which automatically adapts to load and speed changes, reducing impact and wear. The cushioning length is 31 mm, and the impact energy in the end positions is rated at 1.8 J. This feature simplifies setup and helps maintain consistent motion control across varying operating conditions.
Performance and Force Characteristics
At a supply pressure of 6 bar, the theoretical force is 3016 N advancing and 2721 N retracting. These values are essential for calculating the cylinder's capability to drive loads in applications such as pushing, lifting, or clamping. The moving mass at 0 mm stroke is 810 g, with an additional 39 g per 10 mm of stroke, which contributes to the dynamic response of the system. The basic weight is 2720 g, plus 143 g per 10 mm stroke, information useful for structural support and total weight calculations.
The cylinder is designed for use with compressed air per ISO 8573-1:2010 [7:4:4]. Oil lubrication is possible but must be continued if used, as it is required for further operation. This flexibility allows integration into existing lubrication systems, but it also requires careful maintenance planning.
Durability and Environmental Resistance
With a corrosion resistance class (CRC) of 2, the DSBC-80-400-D3-PPSA-N3 is suitable for moderate corrosion stress, making it appropriate for typical industrial environments without aggressive chemicals. The piston rod is made of high-alloy steel, offering inherent corrosion and acid resistance, which extends the service life in humid or mildly corrosive atmospheres. The cylinder also meets LABS (PWIS) conformity per VDMA24364-B1/B2-L, ensuring it is free from materials that could contaminate painted surfaces in automotive or other finishing applications.
The ambient temperature range is -20°C to 80°C, allowing operation in both cold and moderately hot conditions. All materials are RoHS-compliant, and the seals are made from TPE-U(PU) for the piston, wiper, and buffer, with a TPE-E rod wiper and a metal-polymer bearing material. These material choices balance wear resistance and low friction, contributing to reliable long-term performance.
Position Sensing and Integration Flexibility
The DSBC-80-400-D3-PPSA-N3 is prepared for proximity sensor mounting, with sensor slots on three profile sides. This allows for flexible, non-contact position sensing, which is critical for applications requiring precise stroke end detection or intermediate positioning. The cylinder can be mounted using internal threads or with accessories, offering versatility in machine design. The profile barrel design also supports modular mounting options, simplifying integration into existing automation systems.
For engineers, the combination of ISO 15552 compliance, self-adjusting cushioning, and high force output makes this cylinder a practical choice for a wide range of actuation tasks. Its moderate corrosion resistance and LABS conformity broaden its applicability across industries, from general machinery to automotive assembly lines.
Selection Considerations for Buyers
When specifying the DSBC-80-400-D3-PPSA-N3, consider the operating pressure and force requirements. The theoretical forces at 6 bar provide a baseline, but actual force will vary with pressure and friction. The self-adjusting cushioning reduces the need for manual tuning, which can save commissioning time. The cylinder's weight and moving mass are important for applications with high cycle rates or where inertia affects performance.
For procurement teams, the product's adherence to ISO 15552 ensures that spare parts and accessories are widely available. The manufacturer ID is 8165596, and the part number is DSBC-80-400-D3-PPSA-N3. Always verify that the operating medium quality meets ISO 8573-1:2010 [7:4:4] to maintain warranty and performance. The cylinder's ambient temperature range and corrosion resistance class should be matched to the installation environment to avoid premature failure.
