About the Airtac SE100 Standard Air Cylinder SE100BX125SH
The AirTAC SE100BX125SH is a double-acting, single-rod ISO 15552 profile cylinder engineered for severe environments. It delivers a robust 3927 N push force at 0.5 MPa (5497 N at 0.7 MPa) across a 125 mm stroke. Built with a SUS304 stainless steel rod and a high-temperature Viton (FKM) seal, this configuration expands the operating temperature range up to 150 C, making it highly suited for corrosive washdown duties. The extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machinery frames.
Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard impacts when cycling at speeds up to 800 mm/s. Because this unit includes a built-in magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic position sensors without requiring external hardware. The 36 mm cushion length and PT1/2 port ensure standardized energy absorption and airflow for this 100 mm bore class.

Where the Airtac SE100 Standard Air Cylinder SE100BX125SH Is Used
Sterilizer Door Actuation
Handles heavy autoclave doors using 3927 N push force, relying on the Viton seal to withstand 150 C ambient heat and steam exposure.
CNC Chip Blower
Ejects metal chips from a machining center; the SUS304 rod resists cutting fluid corrosion while the 125 mm stroke clears the work envelope.
Hot-Fill Capping Head
Applies precise downward pressure on bottle caps in a hot-fill beverage line, using the adjustable cushion to soften the stroke end.
Is the Airtac SE100 Standard Air Cylinder SE100BX125SH the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—3927 N push at 0.5 MPa—under high heat or washdown conditions. If your force requirements are lower, stepping down to an 80 mm bore reduces push to 2513 N at 0.5 MPa, whereas stepping up to a 125 mm bore increases push to 6136 N at 0.5 MPa. This specific SE100BX125SH configuration pairs a SUS304 rod with a Viton seal, making it the correct choice for food processing or chemical environments where standard TPU seals and carbon steel rods would prematurely fail.
As a double-acting cylinder, it relies on continuous air pressure to hold a load; if air is lost or the valve centers, the piston will drift. For position-holding safety, consider the BSE rod-lock variant. To retrofit this into an existing setup, note the PT1/2 port, the M20x1.5 rod thread, and the ISO 15552 mounting interface, which shares standardized mounting hardware with other profile cylinders. At 125 mm stroke, side loads are minimal, but always verify rod bearing support if guiding heavy off-center 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 SE100 Standard Air Cylinder SE100BX125SH FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, push increases to 5497 N. The maximum push force is 801 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
Yes. The SE series is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards. You can drop it into existing mounts and use shared ISO 15552 hardware. The built-in magnet also works directly with AirTAC CMSE reed and DMSE electronic sensors.
