About the Airtac SE50 Standard Cylinder SE50AX155S
The AirTAC SE50AX155S is a double-acting, single-rod ISO 15552 profile cylinder featuring a 50 mm bore and a 155 mm stroke. It generates 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, making it well-suited for medium-duty positioning tasks. Equipped with a SUS420J2 stainless steel rod, this variant is specifically designed to resist corrosion in washdown or chemically aggressive environments.
The extruded aluminum barrel lacks external tie rods, presenting a clean, compact profile that mounts flush in tight machinery spaces while offering sensor grooves on three sides. Because this unit includes the -S magnet, it is fully ready for position detection using AirTAC CMSE reed or DMSE electronic switches. Field-adjustable pneumatic cushioning at both ends allows you to tune the end-of-stroke deceleration, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX155S Is Used
Flow Wrapper Infeed
Drives the product pusher on a continuous motion flow wrapper, utilizing the 982 N push force and SUS420J2 rod to withstand daily washdowns in food packaging lines.
Bottle Divert Gate
Actuates a diverting flap on a bottling conveyor, where the 155 mm stroke provides precise lateral movement and the adjustable cushion prevents glass breakage on stops.
Lab Sample Ejector
Ejects processed samples from a diagnostic carousel, relying on the SUS420J2 stainless rod for corrosion resistance against reagents and the -S magnet for DMSE electronic position verification.
Is the Airtac SE50 Standard Cylinder SE50AX155S the Right Cylinder?
If your application requires slightly less force, stepping down to the 40 mm bore yields a 628 N push at 0.5 MPa, whereas moving up to the 63 mm bore provides a 1559 N push for heavier payloads. As a standard ISO 15552 profile cylinder, this unit serves as a drop-in dimensional replacement for other ISO 15552 cylinders, simplifying retrofits. The standard PT1/4 port and 155 mm stroke integrate easily with existing plumbing and layouts. For strokes of 300 mm or more, you should add an external guide to prevent rod-bearing bending under side loads. Note that a standard SE cylinder does not hold its position if air pressure is lost; for load-holding safety, consider the 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 SE50AX155S FAQ
The SE50AX155S provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. 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, it is dimensionally interchangeable per the ISO 15552 / VDMA 24562 standard, serving as a drop-in replacement for other ISO 15552 profile cylinders. However, it is a standard double-acting cylinder; the adjustable air cushion only decelerates the piston near stroke end and does not lock or hold the load if air pressure is lost.
