Design and Construction
The Festo DSBC-125-500-PPVA-N3 is a double-acting pneumatic cylinder with a 125 mm piston diameter and a 500 mm stroke. Its profile barrel design, combined with a piston rod made of high-alloy steel and a smooth-anodized aluminum barrel, provides a robust structure suitable for demanding industrial environments. The cylinder conforms to ISO 15552, ensuring dimensional interchangeability with other standard cylinders, which simplifies integration into existing systems.
The unit features adjustable pneumatic cushioning at both ends, with a cushioning length of 45 mm and an impact energy rating of 3.3 J. This allows operators to fine-tune end-of-stroke deceleration, reducing noise and mechanical stress. The low-friction design, aided by a metal-polymer bearing and TPE-U seals, supports smooth, continuous operation while minimizing wear.
Performance and Force Characteristics
At a supply pressure of 6 bar, the cylinder delivers a theoretical advancing force of 7363 N and a retracting force of 6881 N. This makes it suitable for medium to heavy load applications, such as clamping, pressing, or lifting operations. The operating pressure range spans from 0.2 bar to 10 bar, offering flexibility for various pneumatic systems.
The moving mass at zero stroke is 2245 g, with an additional 63 g per 10 mm of stroke. The basic weight is 6768 g, plus 247 g per 10 mm stroke. These values are critical for calculating dynamic loads and selecting appropriate guiding and mounting components.
Position Sensing and Control
Equipped with a magnetic piston, the DSBC-125-500-PPVA-N3 is designed for contactless position sensing via proximity sensors. This feature enables precise and reliable end-position detection, which is essential for automated cycles and sequence control. The absence of mechanical contact in sensing reduces wear and improves repeatability.
The cylinder can be mounted in any orientation, and its piston rod end features an external thread (M27x2) for easy attachment of couplings or tooling. The pneumatic connection is G1/2, a common port size that simplifies piping integration.
Environmental and Material Considerations
This model is built to withstand moderate corrosion stress, classified as CRC 2, and meets the LABS (PWIS) conformity standard VDMA24364-B1/B2-L, making it suitable for use in paint shops and other applications where silicone-free materials are required. The ambient temperature range is -20°C to 80°C, allowing operation in varied industrial climates.
Materials are RoHS-compliant, with die-cast aluminum covers, a wrought aluminum alloy piston, and a high-alloy steel piston rod. The use of TPE-U (PU) for seals and wipers ensures good abrasion resistance, while the cushion piston is made of POM for durability. These material choices contribute to a long service life even under continuous cycling.
Integration and Application Value
For engineers and procurement teams, the DSBC-125-500-PPVA-N3 offers a balance of performance, standardization, and ease of integration. Its ISO 15552 compliance means that existing mounting accessories and spare parts from other compliant cylinders can often be reused, reducing inventory complexity. The adjustable cushioning and low-friction design help maintain consistent cycle times and reduce maintenance intervals.
Typical applications include material handling, packaging machinery, and general automation tasks where reliable linear motion under moderate to heavy loads is required. The cylinder's ability to operate with oil-lubricated compressed air (as per ISO 8573-1:2010 [7:4:4]) provides flexibility in maintenance practices. With a theoretical force output exceeding 7 kN, this unit can replace larger hydraulic cylinders in some applications, offering a cleaner and more energy-efficient alternative.
