Engineered for Precision and Durability
The Festo DSBC-50-125-D3-PPVA-N3 is a double-acting pneumatic cylinder built to ISO 15552, delivering reliable performance for demanding automation tasks. With a 125 mm piston diameter and 50 mm stroke, this cylinder provides substantial force output: theoretical force at 6 bar is 7363 N advancing and 6881 N retracting. The piston rod thread is M27x2, and the pneumatic connection is G1/2, ensuring straightforward integration into existing systems.
The cylinder's structural design—piston, piston rod, and profile barrel—uses high-quality materials: the barrel is smooth-anodized wrought aluminum alloy, the piston rod is high-alloy steel, and seals are made from TPE-U(PU) for extended service life. The unit is RoHS-compliant and rated for corrosion resistance class 2, suitable for moderate corrosive environments. Operating pressure ranges from 0.2 to 10 bar, and ambient temperature can span -20°C to 80°C, making it adaptable to various industrial settings.
Adjustable Cushioning for Controlled Motion
Precise control over end-of-stroke impacts is critical in high-speed automation. The DSBC-50-125-D3-PPVA-N3 features pneumatic cushioning that is adjustable at both ends, allowing you to fine-tune deceleration to match load and speed conditions. The cushioning length is 45 mm, and the impact energy in the end positions is rated at 3.3 J. This adjustability reduces mechanical stress on the cylinder and connected components, minimizing wear and downtime.
Whether you need rapid cycling or gentle positioning, the cushioning system helps maintain smooth operation. The cylinder also exhibits low break-away pressure, ensuring responsive starts even with slow movements, which is essential for precise indexing or transfer applications.
Flexible Mounting and Sensing Options
Installation versatility is a key advantage of this ISO cylinder. The mounting position is any, and type of mounting can be optionally with internal thread or with accessories, giving you freedom in design. The piston rod end is an external thread, and variants include piston rod at one end. This flexibility simplifies integration into both centralized and decentralized automation architectures.
For position feedback, the cylinder is prepared for proximity sensors, enabling reliable end-position detection without additional machining. The piston rod wiper and buffer seals are made from TPE-U(PU), while the bearing uses a metal-polymer compound, all contributing to low friction and consistent performance over many cycles.
Material Quality and Compliance
Material selection directly impacts longevity and maintenance intervals. The DSBC-50-125-D3-PPVA-N3 uses die-cast aluminum covers with a protective coating, a piston made of wrought aluminum alloy, and a cushion piston of POM. The nut and flange screws are galvanized steel, offering resistance to corrosion. The rod wiper is TPE-E, and the cylinder barrel is smooth-anodized to reduce friction and wear.
The cylinder conforms to ISO 15552, ensuring dimensional interchangeability with other standards-compliant actuators. It also meets LABS (PWIS) conformity to VDMA24364-B1/B2-L, making it suitable for use in paint and coating environments where silicone-free operation is required. Operating medium is compressed air per ISO 8573-1:2010 [7:4:4], with oil lubrication possible if needed for downstream processes.
Weight and Integration Considerations
When planning motion systems, weight and inertia are critical. The DSBC-50-125-D3-PPVA-N3 has a basic weight of 6768 g at 0 mm stroke, with an additional 247 g per 10 mm of stroke. The moving mass is 2245 g at 0 mm stroke, plus 63 g per 10 mm stroke. These figures help you calculate dynamic loads and select appropriate guides or supports.
With its robust construction, adjustable cushioning, and compliance with international standards, this Festo cylinder is a practical choice for applications requiring precise, repeatable motion. Its design balances force, speed, and durability, making it suitable for a wide range of industrial automation tasks.
