About the Airtac SE50 Standard Cylinder SE50AX45S
The AirTAC SE50AX45S is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 45 mm stroke. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, scaling up to 1374 N extend force at 0.7 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while leaving three dedicated sensor grooves fully exposed.
This specific configuration features a SUS420J2 stainless steel piston rod (code A) for washdown and corrosive environments, paired with a built-in magnet (code S) for non-contact position sensing using AirTAC CMSE reed or DMSE electronic switches. The field-adjustable pneumatic cushioning at both end caps uses a needle screw to decelerate the piston near stroke end, softening hard mechanical stops without acting as a locking brake.

Where the Airtac SE50 Standard Cylinder SE50AX45S Is Used
Vertical Pouch Sealer
Provides 982 N of extend force at 0.5 MPa to drive the heated sealing jaw on continuous form-fill-seal equipment, while the SUS420J2 rod resists washdown moisture.
Diverter Gate Actuator
Handles the 45 mm stroke to pivot routing flaps on packaging lines, with the -S magnet triggering DMSE electronic sensors to confirm gate position.
Lab Sample Centrifuge
Shifts the access door on analytical centrifuges, utilizing the compact tie-rod-free profile to fit within tight laboratory enclosures.
Is the Airtac SE50 Standard Cylinder SE50AX45S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N of push at 0.5 MPa, whereas stepping up to a 63 mm bore provides 1559 N of push. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or the valve is centered; applications needing static load holding should integrate an external pilot-operated check valve or use the AirTAC BSE rod lock variant. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders using the same 50 mm bore, 45 mm stroke, PT1/4 port, and your selected mounting accessory.
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 SE50AX45S FAQ
The SE50AX45S generates 982 N of push force and 825 N of pull force at 0.5 MPa, and 1374 N of push at 0.7 MPa, with a maximum push of 200 kgf at 1.0 MPa. It features a PT1/4 port and a 20 mm piston rod with an M16x1.5 thread.
Yes, its standardized ISO 15552 mounting dimensions make it a drop-in replacement for other ISO 15552 profile cylinders. However, it is a standard double-acting cylinder, so it cannot hold a load if air is lost; the adjustable air cushion only decelerates the piston near stroke end and does not function as a mechanical lock.
