About the Airtac SE50 Standard Cylinder SE50AX30
The AirTAC SE50AX30 is a double-acting single-rod ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers 982 N of push force at 0.5 MPa and utilizes a 30 mm stroke. This specific SKU features a SUS420J2 stainless steel rod (option A), making it highly suitable for corrosive or washdown environments where a standard carbon steel piston rod would degrade.
The extruded aluminum barrel design omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration via a set screw, protecting machinery from harsh mechanical impacts. Note that this unit lacks a built-in position magnet, so it cannot host CMSE or DMSE sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50AX30 Is Used
Pouch Sealing Jaws
Drives the short 30 mm jaw closure on continuous-flow packaging lines, using the 982 N push force to crimp seals through multi-layer barrier films.
Lab Sample Diverters
Leverages the SUS420J2 stainless steel rod to withstand frequent chemical wipe-downs while actuating sample routing gates in diagnostic equipment.
CNC Chuck Ejectors
Provides a compact 30 mm kick to eject finished machined parts from lathe chucks, utilizing the adjustable cushion to protect spindle bearings.
Is the Airtac SE50 Standard Cylinder SE50AX30 the Right Cylinder?
When sizing this actuator, consider stepping down to a 40 mm bore (providing 628 N push at 0.5 MPa) for lighter loads, or moving up to a 63 mm bore (delivering 1559 N push at 0.5 MPa) if your payload demands greater thrust. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the piston will drift. For position-holding safety, explore the BSE rod-lock variant. As a true ISO 15552 profile cylinder, it offers a drop-in replacement footprint for standardized mounting hardware across various brands.
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 SE50AX30 FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa.
Yes. The SE50AX30 is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting interface and PT1/4 port locations of other standardized profile cylinders, allowing for a direct drop-in retrofit.
