About the Airtac SE50 Standard Cylinder SE50AX105S
The AirTAC SE50AX105S is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering 982 N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) paired with a square extruded aluminum barrel that omits external tie rods, yielding a compact body highly resistant to corrosion and ideal for washdown environments. A built-in magnet (code S) enables seamless position detection.
Field-adjustable pneumatic cushioning at both end caps allows technicians to tune the end-of-stroke deceleration, softening hard impacts when cycling at speeds up to 800 mm/s. Because the barrel lacks protruding tie-rod nuts, the cylinder mounts flush against machine frames, saving valuable space while retaining the full standardized ISO 15552 mounting footprint.

Where the Airtac SE50 Standard Cylinder SE50AX105S Is Used
Vertical Pouch Sealing
Drives the sealing jaw on a vertical form-fill-seal machine, utilizing the 105 mm stroke and 982 N push force to cleanly crimp packaging film in humid food-packing facilities.
Bottle Diverting Gate
Actuates a routing flap on a bottling conveyor, where the SUS420J2 stainless rod withstands daily washdowns and the -S magnet confirms gate position via DMSE sensors.
CNC Lathe Door Latch
Locks the sliding safety door of a CNC lathe, relying on the flush ISO 15552 profile barrel to fit neatly within the machine's tight sheet-metal enclosure.
Is the Airtac SE50 Standard Cylinder SE50AX105S the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore reduces the 0.5 MPa push force to 628 N, whereas stepping up to a 63 mm bore increases it to 1559 N. This SE50AX105S configuration specifies a 105 mm stroke, a PT1/4 port, and the -S magnet for CMSE or DMSE sensors. To replace an existing cylinder, match the 50 mm bore, 105 mm stroke, and mounting accessory, ensuring the profile body clears any adjacent brackets.
Note that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; this unit cannot hold a vertical load without live pressure. If your application requires true position holding, consider the BSE rod-lock variant or an external pilot-operated check valve.
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 SE50AX105S 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, with a maximum push capacity of 200 kgf at 1.0 MPa. It operates at pressures from 0.15-1.0 MPa and speeds of 30-800 mm/s.
Yes, the SE50AX105S is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders by matching the 50 mm bore, 105 mm stroke, PT1/4 port, and your existing mounting hardware. The built-in -S magnet also supports AirTAC CMSE reed and DMSE electronic sensors.
