About the Airtac SE50 Standard Cylinder SE50AX35S
The AirTAC SE50AX35S is a double-acting single-rod profile cylinder built to ISO 15552 standards, delivering a push force of 982 N at 0.5 MPa and a maximum output of 200 kgf at 1.0 MPa. It features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance in washdown or humid environments. The square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames.
Equipped with a built-in magnet (code S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection across its 35 mm stroke. The field-adjustable pneumatic cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard end stops during high-speed cycling up to 800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX35S Is Used
Pouch Sealing Press
Provides the exact 982 N clamping force at 0.5 MPa needed to hold heated jaws against packaging film, while the SUS420J2 rod resists cleaning chemicals.
Bottle Diverter Gate
Executes rapid 35 mm strokes to deflect containers on a filling line, using the integrated magnet and DMSE sensor to confirm gate position.
Lab Dispense Valve
Actuates a precision dosing valve where the stainless steel rod prevents corrosion from aggressive reagents and the compact profile saves space.
Is the Airtac SE50 Standard Cylinder SE50AX35S the Right Cylinder?
Selecting this 50 mm bore makes sense when a 40 mm cylinder (628 N push at 0.5 MPa) lacks thrust or an 80 mm bore (2513 N push at 0.5 MPa) is physically oversized. The PT1/4 port and M16x1.5 rod thread provide a robust interface for this force class. Because it is a double-acting cylinder, it will drift if air pressure is lost or the valve centers; applications requiring dead-load holding need a BSE rod lock or external pilot check valve. Dimensionally interchangeable per ISO 15552, it serves as a direct drop-in replacement for other ISO 15552 cylinders, sharing standard mounting accessories without requiring custom 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 SE50AX35S 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 increases to 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes. The SE50AX35S is dimensionally interchangeable per ISO 15552, meaning it shares standard mounting dimensions and can serve as a drop-in replacement for other ISO 15552 profile cylinders. It uses a PT1/4 port and includes an adjustable air cushion at both ends to fine-tune deceleration.
