About the Airtac SE50 Standard Cylinder SE50AX100S
The AirTAC SE50AX100S is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering 982 N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) engineered for corrosive or washdown environments where a standard carbon steel rod would pit. The extruded aluminum barrel lacks external tie rods, yielding a compact footprint that mounts flush against machine frames.
Because this configuration includes the S option, an internal magnet is fitted for non-contact position sensing using AirTAC CMSE reed or DMSE electronic switches. The cylinder relies on field-adjustable pneumatic cushioning at both ends, allowing technicians to dial in the end-of-stroke deceleration via a set screw rather than relying on a fixed rubber bumper. With a 100 mm stroke and PT1/4 ports, it cycles smoothly at speeds of 30-800 mm/s.

Where the Airtac SE50 Standard Cylinder SE50AX100S Is Used
Pharmaceutical Valve Actuation
Ideal for washdown processing lines, the SUS420J2 stainless rod resists chemical cleaning agents while providing 982 N of force to pivot heavy diverter valves.
Pouch Forming Jaws
Drives vertical sealing jaws on continuous flow wrappers, using the built-in magnet and DMSE sensors to confirm jaw position at high cycling speeds.
Stainless Steel Press Fit
Presses small bearings into marine hardware fittings, where the adjustable end cushions soften the impact at the 100 mm stroke conclusion to protect the assembly.
Is the Airtac SE50 Standard Cylinder SE50AX100S the Right Cylinder?
When sizing this 50 mm bore, compare its 982 N push at 0.5 MPa against the neighboring bores: a 40 mm cylinder provides 628 N, while a 63 mm unit steps up to 1559 N. If your machinery loses air pressure or the directional valve centers, this standard SE cylinder will drift and cannot hold a suspended load—you must pair it with a BSE rod lock or an external pilot-operated check valve for secure positioning. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement sharing the same 50 mm bore, 100 mm stroke, PT1/4 port, and standard mounting accessories. The Ø20 mm rod and M16x1.5 thread provide robust resistance to side loading, though any stroke exceeding 300 mm warrants an external guide to prevent rod-bearing bending.
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 SE50AX100S FAQ
At 0.5 MPa, this 50 mm bore cylinder outputs 982 N push and 825 N pull. At 0.7 MPa, the push force is 1374 N. The maximum rated push is 200 kgf at 1.0 MPa, and the operational speed ranges from 30-800 mm/s.
Yes. The SE50AX100S is dimensionally interchangeable per ISO 15552, meaning it shares the exact same mounting interface, bore, and stroke dimensions. You can use your existing mounting hardware and rod-end joints (like the M16x1.5 thread) for a direct retrofit.
