About the Airtac SE50 Standard Cylinder SE50AX145
The AirTAC SE50AX145 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and a 145 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for moderate-duty industrial motion control. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific configuration incorporates an SUS420J2 stainless steel piston rod (material code A) to resist moisture and washdown chemicals. Unlike fixed rubber bumpers, its integrated pneumatic cushions at both ends are field-adjustable via a screw, allowing you to fine-tune end-of-stroke deceleration for fast-moving loads. Note that this SKU lacks a built-in magnet, so it cannot host CMSE or DMSE position sensors without modification.

Where the Airtac SE50 Standard Cylinder SE50AX145 Is Used
Flow Wrapper End-Sealing
Drives the 145 mm stroke sealing jaw on horizontal flow wrappers, using its 982 N push force to cleanly crimp packaging film ends at high cycle rates.
Diverter Gate Actuation
Pivots sorting diverter arms on logistics conveyor lines, where the corrosion-resistant SUS420J2 rod withstands humid warehouse environments.
Beverage Bottle Rinser
Extends and retracts spray nozzles into glass bottles in a washdown rinse station, benefiting from the stainless rod and adjustable end cushions to prevent harsh mechanical stops.
Is the Airtac SE50 Standard Cylinder SE50AX145 the Right Cylinder?
When sizing this actuator, stepping down to a 40 mm bore reduces the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore increases it to 1559 N. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard 50 mm mounting hardware and a PT1/4 port. Because the stroke is 145 mm, side-load stress on the rod bearing is minimal, but always verify guide alignment. Remember that a standard SE cylinder does not hold its load if air pressure drops; for position holding, consider a BSE rod-lock variant.
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 SE50AX145 FAQ
At 0.5 MPa, the SE50AX145 provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N. The maximum operating pressure is 1.0 MPa, yielding a maximum push force of 200 kgf.
Yes, the SE50AX145 is dimensionally interchangeable per ISO 15552 standards. It shares the exact mounting footprint, 50 mm bore dimensions, PT1/4 port, and M16x1.5 rod thread, allowing it to serve as a drop-in retrofit for other ISO 15552 profile cylinders.
