About the Airtac SE40 Standard Cylinder SE40X20S
The AirTAC SE40X20S is a double-acting single-rod ISO 15552 profile cylinder engineered for compact, short-stroke actuation. It delivers 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for high-cycle clamping and ejection tasks. The extruded aluminum barrel omits external tie rods, yielding a smooth, corrosion-resistant body that mounts flush against machine frames without snagging cables or debris.
Because this unit includes the -S magnet code, it is fully prepared for position sensing using AirTAC CMSE reed switches or DMSE electronic sensors directly in the integrated barrel grooves. The field-adjustable pneumatic cushioning at both ends can be tuned via a set screw to soften end-of-stroke impacts, though with a 20 mm stroke, the cushioning primarily serves to minimize abrupt stops during rapid cycling.

Where the Airtac SE40 Standard Cylinder SE40X20S Is Used
CNC Machining Clamps
Ideal for securing aluminum castings during CNC milling, utilizing the 628 N push force and short 20 mm stroke to lock parts rapidly against fixed locators.
Carton Flap Ejectors
Provides rapid, repetitive ejection of folded cardboard cartons from sealing lines, where the compact 40 mm bore and integrated DMSE position sensing ensure precise timing.
Component Press Fitting
Drives small bushings into die-cast housings on automated assembly lines, using the 879 N push force at 0.7 MPa to seat parts without overshooting.
Is the Airtac SE40 Standard Cylinder SE40X20S the Right Cylinder?
Selecting this 40 mm bore cylinder is optimal when your application requires the 628 N push force at 0.5 MPa. If your load demands less force, you can step down to the 32 mm bore, which provides 402 N of push at 0.5 MPa. Conversely, if you need to move heavier payloads, stepping up to the 50 mm bore yields 982 N of push at 0.5 MPa. Keep in mind that a standard double-acting SE cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. For load-holding requirements, consider the BSE rod lock variant or an external pilot-operated check valve.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a drop-in replacement for other ISO 15552 profile cylinders, sharing standardized mounting hardware. This specific configuration features a PT1/4 port, a 16 mm rod with an M12x1.25 thread, and a built-in -S magnet for CMSE / DMSE sensors.
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 SE40 Standard Cylinder SE40X20S FAQ
The SE40X20S provides 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 879 N. The maximum push force is 128 kgf at 1.0 MPa.
Yes. The SE40X20S is built to the ISO 15552 / VDMA 24562 dimensional standard, meaning it is a drop-in replacement for other ISO 15552 profile cylinders. It shares identical mounting interface dimensions and uses a PT1/4 port.
