The Festo DSBC-50-80-PPVA-N3 is a double-acting pneumatic cylinder built to ISO 15552, Festo part number 1366951. It has a piston diameter of 50 mm, a stroke of 80 mm and a 20 mm piston rod with an M16x1.5 male thread. At 6 bar it develops a theoretical force of 1178 N advancing and 990 N retracting, it weighs 1638 g, and the moving mass is 565 g.
This is the PPVA version, with pneumatic end-position cushioning that is adjustable at both ends. An adjusting screw in each cover lets you tune the deceleration to the actual load and speed, which is what you want when the same cylinder has to run different parts or when the machine is set up once and left alone. Cushioning length is 22 mm and each end position absorbs up to 1 J of impact energy.
The barrel is smooth-anodised wrought aluminium with an integrated sensor slot, so proximity switches sit flush in the profile and add nothing to the width of the cylinder. The covers are coated die-cast aluminium, the piston rod is high-alloy steel and the seals are polyurethane. Because the cylinder follows ISO 15552, also published as ISO 6431 and VDMA 24562, it is dimensionally interchangeable with any other ISO cylinder of the same bore and stroke, whatever brand is fitted on the machine now.
Air ports are G1/4 at both ends, the operating pressure range is 0.4 to 12 bar and the ambient temperature range is -20 to +80 degrees C. The cylinder mounts through the internal threads in the covers or with the standard ISO 15552 accessories: foot mounting, front and rear flange, swivel flange, trunnion and rod clevis.

Dimensions
The official Festo dimension drawing for the DSBC series is in the image gallery on this page, with all the ISO 15552 reference letters. Overall length is the basic length for the 50 mm bore plus the 80 mm stroke. The product photo shows a DSBC in this bore size; the barrel length on the cylinder you receive follows the stroke you order. Ask us for the Festo datasheet of part number 1366951 and we will send the complete dimension table.
What the DSBC-50-80-PPVA-N3 is used for
- Clamping, feeding and ejecting on assembly and packaging machines
- Opening and closing gates, flaps, diverters and pusher arms on conveyor lines
- Filling, capping and labelling machines in beverage and food plants
- Presses, moulding machines and material handling where an ISO cylinder has to be replaced like for like
- Machine building where the mounting has to follow ISO 15552 so any brand can be fitted later
Frequently asked questions
What does the type code DSBC-50-80-PPVA-N3 mean?
DSBC is the Festo series for standards-based double-acting cylinders to ISO 15552. The first number is the piston diameter in millimetres, so 50 mm, and the second is the stroke, so 80 mm. PPV stands for pneumatic cushioning that is adjustable at both ends. The A means the cylinder is prepared for proximity sensors in the integrated sensor slot. The N3 at the end is the Festo suffix for this standard configuration, so quote the complete type code or the Festo part number 1366951 when ordering.
What is the difference between the PPSA and the PPVA version?
Both use pneumatic air cushioning in the end positions and both give the same force and the same dimensions. On the PPVA version you set the cushioning yourself with an adjusting screw at each end, which lets you tune it exactly for one load and one speed. On the PPSA version the cushioning adjusts itself: no screws to set, faster commissioning, and it stays correct if the load or the cycle time changes. PPSA is the easier choice on a new machine; PPVA is the choice when an engineer wants direct control over the deceleration.
How much force does the DSBC-50-80-PPVA-N3 give at other pressures?
Theoretical force is the piston area multiplied by the pressure, so it scales almost linearly. This 50 mm cylinder gives about 1178 N advancing at 6 bar, roughly 785 N at 4 bar and roughly 1571 N at 8 bar. Retracting force is lower because the piston rod takes up part of the piston area: 990 N at 6 bar. Allow for friction and for the load factor of your application, so size the cylinder above the calculated static force.
Which sensors fit the Festo DSBC?
The DSBC profile has an integrated sensor slot, so slot-mounted proximity switches drop straight in without a bracket. The usual choices are the SMT-8M, SME-8M and SDBT-MSX for magnetic sensing, wired with NEBU connecting cables. Two sensors are normally fitted, one for the advanced position and one for the retracted position. We supply the sensors and cables with the cylinder if you ask for them in the same request.
Is the DSBC-50-80-PPVA-N3 interchangeable with cylinders from other brands?
Yes, dimensionally. ISO 15552, formerly ISO 6431 and VDMA 24562, fixes the mounting dimensions, the port positions, the piston rod thread and the overall length for each bore size. A DSBC with a 50 mm bore and a 80 mm stroke will bolt into the same place as an ISO cylinder of the same size from SMC, Airtac, Camozzi, Parker or Bosch Rexroth. What differs is the cushioning behaviour, the seal package and the service life, not the mounting.
Can I get this cylinder with a different stroke?
Yes. Festo builds the DSBC to any stroke from 1 mm to 2800 mm, and the standard stroke lengths from 20 to 500 mm are listed on this site with their own part numbers. Non-standard strokes are made to order with a longer lead time. Tell us the stroke you need and we will confirm the part number, the price and the delivery time.
