About the Airtac SE40 Standard Cylinder SE40BX25S
The AirTAC SE40BX25S 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 features a SUS304 stainless steel piston rod (code B) for superior resistance to corrosion and washdown chemicals. The extruded aluminum barrel omits external tie rods, yielding a smooth, flush profile that is easy to mount and clean.
This 40 mm bore unit includes a built-in magnet (code S) for non-contact position sensing using AirTAC CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends allow you to tune end-of-stroke deceleration, protecting tooling during rapid 30-800 mm/s cycles.

Where the Airtac SE40 Standard Cylinder SE40BX25S Is Used
Stainless Food Diversion Gate
Actuates a short-stroke flap gate in a food packaging line, utilizing the SUS304 rod for washdown durability and 628 N push to overcome product friction.
PCB Clamp and Release
Provides rapid 25 mm clamping strokes on an electronics assembly fixture, using the built-in magnet to trigger DMSE electronic sensors for precise timing.
Lab Dispenser Positioning
Moves a chemical dispenser nozzle in a laboratory setting, relying on the corrosion-resistant stainless rod and adjustable cushions to prevent fluid splashing.
Is the Airtac SE40 Standard Cylinder SE40BX25S the Right Cylinder?
Select this 40 mm bore when an application requires 628 N push at 0.5 MPa but lacks the physical envelope for a 50 mm cylinder (which provides 982 N push). If your load is lighter, stepping down to a 32 mm bore yields 402 N push in an even smaller footprint. Because this is a 25 mm stroke, side-loading on the M12x1.25 rod thread is minimal, though external guides are always recommended for offset loads.
This SE40BX25S is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 cylinders. It uses a PT1/4 port, accepts standard mounting accessories, and the -S magnet enables direct sensor integration. Note that standard double-acting cylinders drift if air pressure is lost; use a BSE rod lock variant if the load must be held mechanically during an outage.
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 SE40BX25S FAQ
