Airtac SE50 Standard Cylinder SE50X625S
The AirTAC Airtac SE50 Standard Cylinder SE50X625S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 625mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50X625S
The AirTAC SE50X625S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 625 mm stroke. It generates 982 N of push force at 0.5 MPa and features a Ø20 mm piston rod with an M16x1.5 thread. Because this 625 mm length exceeds the standard maximum stroke for this bore, it is supplied as a non-standard, made-to-order unit.
The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush in tight spaces. Equipped with a built-in magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-travel detection without external hardware.

Where the Airtac SE50 Standard Cylinder SE50X625S Is Used
Pallet Transfer Line Diverter
Uses the 625 mm stroke and 982 N push to extend and reroute heavy pallets between adjacent conveyor belts, relying on the adjustable cushion to soften end stops at high speed.
Large Carton Erector Arm
Drives the folding mechanism on heavy-duty corrugated box formers, where the built-in magnet triggers a DMSE sensor to confirm the 625 mm extension before glue application.
Coating Dip-and-Lift Mechanism
Slowly lowers and raises product racks through a chemical bath, using the 982 N pull to extract submerged parts while the field-adjustable cushion prevents sudden fluid splashing at stroke end.
Is the Airtac SE50 Standard Cylinder SE50X625S the Right Cylinder?
With a 982 N push at 0.5 MPa, this bore fits medium-duty positioning. If your load is lighter, stepping down to the 40 mm bore reduces the push to 628 N, saving air volume. For heavier payloads, the 63 mm bore raises the push to 1559 N. This SE50X625S uses a PT1/4 port and includes the -S magnet for CMSE/DMSE switches. As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other ISO 15552 cylinders, simplifying retrofits.
At 625 mm, the unsupported stroke length increases the risk of rod-bearing bending under side loads; always use an external guide to prevent premature wear. Note that a plain SE cylinder does not hold its load when air is exhausted—the piston drifts—so add a BSE rod lock if position holding is required.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
Airtac SE50 Standard Cylinder SE50X625S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force reaches 1374 N. The maximum push force is 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, and the operating speed range is 30-800 mm/s.
Yes. The SE50X625S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and PT1/4 port locations of other ISO 15552 profile cylinders. It features an extruded aluminum barrel without external tie rods and includes a built-in magnet for AirTAC CMSE and DMSE sensors.
