Overview and Key Specifications
The Festo DSBC-125-160-D3-PPVA-N3 is a double-acting pneumatic cylinder with a 125 mm piston diameter and a 160 mm stroke. It conforms to ISO 15552, ensuring dimensional interchangeability with other cylinders built to the same standard. The cylinder operates within a pressure range of 0.2 to 10 bar and is designed for use with compressed air per ISO 8573-1:2010 [7:4:4]. Its theoretical force output is 7363 N advancing and 6881 N retracting at 6 bar, making it suitable for medium-to-heavy duty applications.
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 in end positions. This allows engineers to fine-tune deceleration to reduce shock and noise, particularly in high-speed or high-cycle operations. The cylinder's mounting position is unrestricted, and it can be mounted using internal threads or accessories, offering flexibility in machine design.
Construction and Materials
The DSBC-125-160-D3-PPVA-N3 is built with a profile barrel made of smooth-anodized wrought aluminum alloy, while the piston and covers are also aluminum-based. The piston rod is made of high-alloy steel with an external thread (M27x2), providing strength and wear resistance. Seals and wipers are primarily TPE-U (PU), with a rod wiper in TPE-E and a cushion piston in POM. The bearing uses a metal-polymer compound, and fasteners are galvanized steel. These materials are RoHS-compliant and chosen to withstand moderate corrosion stress (CRC 2 per Festo standard 940 070). The cylinder also meets LABS (PWIS) conformity to VDMA24364-B1/B2-L, which is important for paint and adhesive applications where silicone-free operation is required.
Position Sensing and Control
This model includes the D3 variant, which provides sensor slots on three sides of the profile barrel. This feature enables flexible mounting of proximity sensors to detect piston position without mechanical contact, simplifying setup and allowing for easy adjustment of sensing points. The slots are designed for standard proximity sensors, and the three-sided configuration gives designers more freedom in sensor placement, which is especially useful in tight spaces or when multiple sensing positions are needed along the stroke.
Application Considerations
With a piston diameter of 125 mm and a stroke of 160 mm, the DSBC-125-160-D3-PPVA-N3 is well-suited for applications requiring moderate to high force in a compact envelope. Examples include clamping, pressing, feeding, and lifting operations in automation lines, packaging machinery, and material handling equipment. The adjustable cushioning is particularly beneficial for moving heavy loads at higher speeds, as it helps prevent end-of-stroke impacts that can cause wear or product damage.
Engineers should note that the cylinder's 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 figures are important for calculating dynamic loads and selecting appropriate mounting brackets and guides. The pneumatic connection is G1/2, and the piston rod thread is M27x2, so mating components must be sized accordingly.
Integration and Environmental Suitability
The DSBC-125-160-D3-PPVA-N3 can be operated with or without oil lubrication, but if oil is used, it must be continued to ensure proper seal life. The ambient temperature range is -20°C to 80°C, allowing use in both cold and warm environments. The cylinder's corrosion resistance class of 2 indicates it can handle moderate corrosion stress, such as in humid or mildly contaminated industrial settings, but it is not intended for aggressive chemical exposure.
For procurement teams, this cylinder's ISO 15552 compliance ensures that it can be replaced or integrated with other standard components, reducing inventory complexity. The availability of sensor slots and multiple mounting options also simplifies machine assembly and reduces the need for custom brackets. Overall, the DSBC-125-160-D3-PPVA-N3 offers a balanced combination of force, stroke, and adjustability, making it a reliable choice for many pneumatic actuation tasks.
