About the Airtac SE50 Standard Cylinder SE50AX115
The AirTAC SE50AX115 is a double-acting, single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 115 mm stroke. It delivers a robust 982 N push force at 0.5 MPa, making it well-suited for mid-range automation tasks. The rod is constructed from SUS420J2 stainless steel (code A), providing excellent corrosion resistance for washdown or humid environments.
This model utilizes a square extruded aluminum barrel without external tie rods, resulting in a compact footprint that mounts flush against machinery. The barrel also features sensor grooves on three sides, though this specific SKU omits the built-in magnet and does not support position sensing. Field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration, protecting the internal components from hard impacts.

Where the Airtac SE50 Standard Cylinder SE50AX115 Is Used
Flow Wrapper End-Sealing
Drives the sealing jaw head on continuous-motion flow wrappers, utilizing the 982 N push force to cleanly crimp packaging film seams at high cycle rates.
Bottle Divert Gate
Actuates a diverter arm on a stainless steel conveyor line, where the SUS420J2 rod withstands splash exposure from washdown routines.
Lab Centrifuge Housing Clamp
Secures the outer shell of laboratory centrifuges during high-speed rotation, relying on the flush profile barrel to fit within tight machine frames.
Is the Airtac SE50 Standard Cylinder SE50AX115 the Right Cylinder?
If 982 N of push at 0.5 MPa is excessive for your load, stepping down to the 40 mm bore yields 628 N. Conversely, if your application demands higher thrust, the 63 mm bore provides 1559 N. Because this is a standard 115 mm stroke, it falls well within the 1200 mm maximum standard stroke limit for this bore.
This plain SE cylinder cannot hold a load or maintain its position if air pressure is lost or the valve is centered; the piston will drift. For applications requiring mid-stroke holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement sharing standard mounting hardware and a PT1/4 port.
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 SE50AX115 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 is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX115 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface and PT1/4 port size as other ISO 15552 cylinders, allowing for a direct drop-in retrofit using your existing mounting hardware.
