Overview and Key Specifications
The Festo DSBC-63-400-D3-PPSA-N3 is a double-acting pneumatic cylinder with a 63 mm piston diameter and a 400 mm stroke, designed to meet ISO 15552 standards. It is built for applications requiring reliable linear motion under moderate corrosion stress (CRC 2) and can operate in ambient temperatures from -20°C to 80°C. The cylinder operates with compressed air per ISO 8573-1:2010 [7:4:4] and can be used with oil lubrication if needed for further use.
Key technical parameters include a theoretical force of 1870 N advancing and 1682 N retracting at 6 bar, with an operating pressure range of 0.4 to 12 bar. The piston rod thread is M16x1.5, and the pneumatic connection is G3/8. The cylinder has a basic weight of 1774 g with 0 mm stroke, adding 92 g per 10 mm stroke, and a moving mass of 430 g at 0 mm stroke, adding 25 g per 10 mm stroke.
Design and Construction
The DSBC-63-400-D3-PPSA-N3 features a profile barrel design with a piston and piston rod, constructed from high-quality materials. The cylinder barrel is made of smooth-anodized wrought aluminum alloy, while the piston is also wrought aluminum alloy. The piston rod is high-alloy steel, and seals are made of TPE-U(PU) for the piston, rod wiper, and buffer, with a TPE-E rod wiper. The cushion piston is POM, and bearings use a metal polymer compound. Covers are die-cast aluminum with a coating, and all materials are RoHS-compliant.
The cylinder is designed for durability under demanding conditions, including alternating loads and fluctuating pressures. Its corrosion resistance class of 2 indicates moderate corrosion stress capability, making it suitable for typical industrial environments.
Performance and Cushioning
Self-adjusting pneumatic end-position cushioning ensures smooth deceleration at the end of stroke, even when loads or pressures vary. This feature reduces impact energy (rated at 1.3 J in end positions) and extends cylinder life by minimizing mechanical stress. The cushioning length is 22 mm, providing effective energy absorption for the specified stroke and force range.
The cylinder's double-acting mode allows controlled motion in both directions, and its mounting position is unrestricted (any orientation). With a piston diameter of 63 mm, it delivers substantial force for medium-duty automation tasks.
Position Sensing and Integration
Sensor slots on three sides of the cylinder enable precise position sensing using proximity sensors. This design flexibility allows for easy integration of sensors to detect piston position, which is critical for sequence control and automation accuracy. The cylinder is prepared for proximity sensor mounting, simplifying installation and reducing setup time.
The DSBC-63-400-D3-PPSA-N3 conforms to ISO 15552, ensuring interchangeability with other cylinders of similar standards. It offers versatile mounting options, including internal threads or accessories, and the piston rod end has an external thread (M16x1.5). The cylinder can be mounted in any position, providing design freedom for machine builders.
Applications and Selection Considerations
This cylinder is well-suited for applications in packaging, material handling, and general automation where reliable linear actuation is required. Its 400 mm stroke and 63 mm bore make it ideal for pushing, pulling, lifting, or clamping operations with moderate loads. The self-adjusting cushioning is particularly beneficial in high-cycle applications where load conditions may change.
When selecting this cylinder, consider the operating pressure range (0.4 to 12 bar) and the theoretical forces at your system pressure. The moving mass and additional weight per stroke are important for dynamic calculations. The LABS (PWIS) conformity to VDMA24364-B1/B2-L ensures compatibility in paint and coating environments. With a corrosion resistance class of 2, it is not intended for harsh corrosive conditions but is adequate for most factory floor environments.
