About the Airtac SE40 Standard Cylinder SE40BX50
The AirTAC SE40BX50 is a double-acting, single-rod ISO 15552 profile cylinder engineered for demanding environments. It delivers 628 N of push force and 528 N of pull force at 0.5 MPa, utilizing a 16 mm SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically exposed settings.
Its square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush while resisting contamination. The field-adjustable pneumatic cushioning at both ends allows you to precisely tune end-of-stroke deceleration, protecting payloads moving at speeds up to 800 mm/s. Because this specific SKU lacks a built-in magnet, it is not equipped for CMSE or DMSE position sensing out of the box.

Where the Airtac SE40 Standard Cylinder SE40BX50 Is Used
Flow Wrapper Infeed
Pushes product into the wrapping jaw with 628 N of thrust at 0.5 MPa, where the SUS304 rod withstands daily washdown chemistry.
Diverter Gate Actuation
Handles rapid 50 mm stroke diverting on food-grade lines, benefiting from the tie-rod-free profile that prevents debris accumulation.
Lab Sample Ejection
Ejects processed samples from testing cartridges, relying on the adjustable end cushions to soften impacts at high cycle rates.
Is the Airtac SE40 Standard Cylinder SE40BX50 the Right Cylinder?
If your application requires less thrust, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa, while moving up to the 50 mm bore provides 982 N for heavier loads. As a standard ISO 15552 cylinder, this 40 mm bore with a 50 mm stroke, PT1/4 port, and basic mounting is dimensionally interchangeable with other ISO 15552 profile cylinders for seamless retrofits. Note that the adjustable air cushion only decelerates the piston near stroke end; it does not hold a load. If position holding without live air pressure is required, consider the BSE rod lock variant.
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 SE40BX50 FAQ
At 0.5 MPa, the SE40BX50 delivers 628 N push and 528 N pull. At 0.7 MPa, push increases to 879 N, with a maximum push of 128 kgf at 1.0 MPa. It features a 16 mm rod, an M12x1.25 rod-end thread, and a PT1/4 port.
This specific SKU does not include a built-in magnet, so it cannot support CMSE or DMSE electronic sensors without modification. Additionally, the adjustable air cushion only decelerates the piston near the stroke end and does not function as a brake; it will not hold a load if air pressure is lost.
