About the Airtac SE50 Standard Cylinder SE50X5S
The AirTAC SE50X5S is a double-acting single-rod ISO 15552 profile cylinder engineered for ultra-short 5 mm strokes, delivering 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush within tight machine envelopes. The integrated -S magnet enables direct fitment of CMSE reed and DMSE electronic sensors along the triple-sided sensor grooves for precise end-of-travel signaling.
Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-stop deceleration via a set screw, protecting the mechanism during high-speed 30-800 mm/s cycling. Because this is a standard ISO 15552 footprint, it serves as a drop-in replacement for any cylinder sharing the VDMA 24562 mounting interface, streamlining retrofits without altering existing fixture dimensions.

Where the Airtac SE50 Standard Cylinder SE50X5S Is Used
Stamping Press Ejection
Uses the 5 mm stroke to deliver a rapid 982 N push at 0.5 MPa for knocking small stamped metal parts out of a die on every machine cycle.
Carton Flap Folding
Employs the ultra-short stroke and built-in DMSE electronic sensor magnet to tuck packaging flaps at high speed before tape application.
PCB Test Fixture Clamping
Leverages the compact, tie-rod-free extruded profile to securely hold delicate circuit boards in an inspection jig without over-traveling.
Is the Airtac SE50 Standard Cylinder SE50X5S the Right Cylinder?
Selecting the SE50X5S is ideal when a brief 5 mm extension is required with moderate thrust. If you need less power, step down to the 40 mm bore, which provides 628 N of push at 0.5 MPa. If your fixture demands more force, step up to the 63 mm bore, yielding 1559 N of push at 0.5 MPa. This 50 mm bore utilizes a PT1/4 port and an M16x1.5 rod thread, matching the standard ISO 15552 mounting dimensions and sharing hardware with similar profile cylinders.
Keep in mind that a plain SE cylinder does not hold a load when air pressure is lost or the valve is centered; the piston will drift. If your 5 mm stroke application requires strict position holding without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve. Furthermore, because the stroke is only 5 mm, side-load stress on the rod bearing is minimal compared to longer strokes, though external guides remain best practice for offset loads.
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 SE50X5S FAQ
The SE50X5S 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, with a maximum push of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
