About the Airtac SE50 Standard Cylinder SE50X680S
The AirTAC SE50X680S is a double-acting, single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa) over a 680 mm stroke. Because it uses a square extruded aluminum barrel without external tie rods, the body is highly corrosion-resistant and mounts flush against machine frames, saving valuable space in tight assemblies.
This specific unit includes the -S magnet option for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors, providing reliable end-of-stroke signaling. The integrated field-adjustable air cushions at both ends allow you to fine-tune the deceleration of the piston via a set screw, effectively softening hard end stops during high-speed 30-800 mm/s operations.

Where the Airtac SE50 Standard Cylinder SE50X680S Is Used
Corrugated Box Erector
Provides the 982 N push force required to open and square flat corrugated blanks, while the -S magnet triggers DMSE sensors to confirm full 680 mm extension before folding flaps.
Pallet Transfer Gate
Actuates a diverter gate on a 30-meter packaging line, utilizing the 680 mm stroke to reroute heavy wooden pallets onto a secondary spur conveyor without tie-rod interference.
Lab Sample Carousel Indexer
Drives a multi-position sample carousel in diagnostic automation, using the adjustable pneumatic cushion to bring the 680 mm travel to a smooth, vibration-free stop.
Is the Airtac SE50 Standard Cylinder SE50X680S the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 982 N of push force. If your application requires less force, the neighboring 40 mm bore provides 628 N; conversely, stepping up to the 63 mm bore yields 1559 N for heavier payloads. Keep in mind that a standard SE cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift. For position holding without live pressure, consider the BSE rod lock variant or an external pilot-operated check valve.
For a 680 mm stroke, the 20 mm rod and M16x1.5 thread provide a robust interface, but long unsupported strokes inherently introduce rod-bearing bending risks. To prevent premature seal wear and piston rod damage, always guide the load externally or use a linear rail. Being dimensionally interchangeable per ISO 15552, this cylinder serves as a drop-in replacement for other ISO 15552 cylinders, sharing standard mounting hardware like FA front flanges or LB foot brackets.
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 SE50X680S FAQ
The SE50X680S delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, the push force is 1374 N. The maximum push capacity is 200 kgf (approx. 1961 N) at the maximum operating pressure of 1.0 MPa.
Yes. The SE50X680S is dimensionally interchangeable per ISO 15552, meaning it shares the exact same mounting footprint, port sizes (PT1/4), and rod-end thread (M16x1.5) as other standard ISO 15552 profile cylinders, allowing for a seamless drop-in retrofit.
