Airtac SE50 Standard Cylinder SE50AX240
The AirTAC Airtac SE50 Standard Cylinder SE50AX240 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø50mm bore and 240mm stroke, PT1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE50 Standard Cylinder SE50AX240
The AirTAC SE50AX240 is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a push force of 982 N at 0.5 MPa and a maximum of 200 kgf at 1.0 MPa. It features a 50 mm bore, a 240 mm stroke, and PT1/4 ports. Code "A" designates a SUS420J2 stainless steel piston rod, making this specific SKU highly suitable for corrosive environments or washdown duty where a standard hard-chrome rod would degrade.
This unit utilizes a square extruded aluminum barrel without external tie rods, yielding a compact footprint that mounts flush against machine frames. The barrel integrates sensor grooves on three sides, though this particular SKU lacks the built-in magnet (no -S code) and therefore cannot support CMSE or DMSE electronic position sensors without modification. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX240 Is Used
Bottling Line Diverter
Uses the 982 N push force and SUS420J2 stainless rod to deflect containers on a washdown beverage line, resisting moisture corrosion while handling repetitive lateral transfers.
Pallet Flap Tucker
Employs the 240 mm stroke to reach across a palletizing cell, folding corrugated box flaps flat before strapping, relying on adjustable cushioning to soften end stops.
Seafood Sorter Gate
Leverages the 200 kgf max thrust and stainless steel construction to push marine product sorting chutes in high-humidity, saline environments without rod pitting.
Is the Airtac SE50 Standard Cylinder SE50AX240 the Right Cylinder?
When sizing this actuator, compare its 982 N push at 0.5 MPa against your actual load. If you need less force, stepping down to the 40 mm bore drops the push output to 628 N. If your application requires more thrust, stepping up to the 63 mm bore increases the 0.5 MPa push to 1559 N. Because this model uses a SUS420J2 stainless steel rod, it is purpose-built for moisture-exposed machinery rather than general dry automation.
With a 240 mm stroke, the unsupported rod extension is significant; to prevent rod-bearing bending and premature seal wear under lateral stress, you must use an external guide to carry the load. As a standard double-acting cylinder, it does not hold its position or load when air pressure is lost or the valve is centered—the piston will drift. If your process requires fail-safe load holding, you need a BSE rod lock variant or an external pilot-operated check valve. For ISO 15552 retrofits, this cylinder is dimensionally interchangeable with other 50 mm bore profile cylinders, matching the standard PT1/4 port size and mounting interface.
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 SE50AX240 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa.
No, this specific SKU does not have a built-in magnet (no -S code), so it cannot trigger AirTAC CMSE reed or DMSE electronic sensors. You would need the SE50AX240S variant for position detection.
