About the Airtac SE100 Standard Air Cylinder SE100BX125S
The AirTAC SE100BX125S is a double-acting single-rod profile cylinder built to the ISO 15552 standard, delivering a robust 3927 N push force at 0.5 MPa. It features a SUS304 stainless steel piston rod (code B) specifically engineered for corrosive environments and washdown duty. This makes it highly suitable for food processing or packaging lines where moisture and chemicals are present.
The extruded aluminum barrel design eliminates external tie rods, creating a smooth, compact profile that mounts flush against machine frames. Equipped with a built-in magnet (code S), the cylinder interfaces directly with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Field-adjustable air cushions at both ends allow you to tune the deceleration of the 125 mm stroke, softening hard end stops during high-speed cycling.

Where the Airtac SE100 Standard Air Cylinder SE100BX125S Is Used
Stainless Pouch Sealing
Drives the sealing jaws on continuous vertical form-fill-seal machines, utilizing the SUS304 rod to resist washdown chemicals while delivering 3927 N of precise sealing pressure.
Heavy Pallet Diverters
Actuates heavy-duty routing gates on pallet conveyors, where the 125 mm stroke and 5497 N push force at 0.7 MPa reliably redirect fully loaded pallets onto spur lines.
Beverage Crate Stacking
Powers the lifting arms in automated bottling lines, using the integrated magnet for DMSE electronic sensors to confirm crate positioning in wet, rinse-down environments.
Is the Airtac SE100 Standard Air Cylinder SE100BX125S the Right Cylinder?
Selecting this 100 mm bore provides a maximum thrust of 801 kgf at 1.0 MPa, stepping up considerably from the 80 mm bore which yields 2513 N push at 0.5 MPa. If your application requires less force, dropping down to that 80 mm neighbor saves space and air consumption; if you need more power, the 125 mm bore offers 6136 N push at 0.5 MPa. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standardized mounting accessories like FA front flanges or TC trunnions.
Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve centers, so it cannot hold a vertical load safely without a pilot-operated check valve or a dedicated BSE rod lock variant. The PT1/2 port and M20x1.5 rod thread handle high flow rates and substantial side loads, though any stroke over 300 mm would require an external guide to prevent rod-bearing bending.
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.
