About the Airtac SE50 Standard Cylinder SE50AX270
The AirTAC SE50AX270 is a double-acting single-rod ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa over a 270 mm stroke. Its square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting corrosion. This specific SKU utilizes a SUS420J2 stainless steel rod, making it highly suitable for environments where moisture or washdown chemicals would degrade a standard carbon steel shaft.
Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s. Because this configuration lacks the -S magnet suffix, it is not equipped for direct CMSE or DMSE position sensing without modification. The cylinder operates on filtered air between 0.15 and 1.0 MPa, relying on its PT1/4 ports and M16x1.5 rod thread to integrate seamlessly into existing pneumatic setups.

Where the Airtac SE50 Standard Cylinder SE50AX270 Is Used
Carton Erector Arms
Drives the folding mechanisms in corrugated box erectors, where the 982 N push force reliably breaks cardboard resistance and the SUS420J2 rod withstands humid paper-mill environments.
Bottle Divert Gates
Actuates routing flaps on beverage lines to sort containers, utilizing the 270 mm stroke to clear the conveyor lane while the stainless rod resists washdown chemicals.
Lab Sample Indexing
Pushes diagnostic sample racks to the next testing station, benefiting from the smooth adjustable cushioning to prevent fluid spillage from open vials at stroke end.
Is the Airtac SE50 Standard Cylinder SE50AX270 the Right Cylinder?
Selecting this 50 mm bore makes sense when your application requires 982 N of push at 0.5 MPa. If your load is lighter, stepping down to the 40 mm bore drops the output to 628 N, saving physical space and air volume. Conversely, if you need more authority, the 63 mm bore increases the push capacity to 1559 N. Keep in mind that a plain SE cylinder drifts when air pressure is lost or the valve centers; if your 270 mm stroke mechanism must hold a vertical load without live pressure, you should integrate an external pilot-operated check valve or explore the BSE rod-lock variant.
With a 270 mm stroke, the M16x1.5 rod and internal bearing face increased bending moments under side loads, so an external guide rail is recommended to prevent premature seal wear. This model is dimensionally interchangeable per ISO 15552, meaning it serves as a direct drop-in replacement for other ISO 15552 profile cylinders using the same PT1/4 porting and standard mounting accessories.
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 SE50AX270 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 increases to 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates at speeds ranging from 30 to 800 mm/s.
Yes, the SE50AX270 is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders with a 50 mm bore, 270 mm stroke, and PT1/4 ports, without claiming exact brand equivalence.
