About the Airtac SE40 Standard Cylinder SE40BX30
The AirTAC SE40BX30 is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation in demanding environments. It delivers a theoretical push force of 628 N at 0.5 MPa, utilizing a 16 mm rod and an M12x1.25 thread. Because this SKU uses a SUS304 stainless steel rod (code B), it is purpose-built for corrosive or washdown applications where a standard carbon steel rod would fail prematurely.
The extruded aluminum barrel design eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames while resisting environmental degradation. Although this specific configuration lacks a position-sensing magnet, the body retains sensor grooves on three sides for future mechanical flexibility. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, protecting payloads from harsh mechanical impacts.

Where the Airtac SE40 Standard Cylinder SE40BX30 Is Used
Lab Diagnostic Centrifuge
Actuates a compact sample tray lid on a diagnostic centrifuge, where the SUS304 rod withstands harsh chemical disinfectants and the 628 N push force secures the latch during high-RPM spinning.
Pouch Filling Nozzle
Drives a diverter valve on a food-grade pouch filling line, utilizing the 30 mm stroke to rapidly shift product flow while the stainless rod survives daily high-pressure washdowns.
PCB Router Clamp
Provides localized clamping on a printed circuit board routing station, where the short stroke and adjustable cushioning prevent delicate board delamination during the cutting cycle.
Is the Airtac SE40 Standard Cylinder SE40BX30 the Right Cylinder?
Selecting this 40 mm bore makes sense when your application requires roughly 628 N of push force at 0.5 MPa. If you need less clamping power, stepping down to the 32 mm bore yields 402 N of push; conversely, scaling up to the 50 mm bore provides 982 N. This model features a PT1/4 port and a 30 mm stroke, making it dimensionally interchangeable with other ISO 15552 cylinders for seamless retrofits using standardized mounting hardware like FA or LB brackets. Note that a plain SE cylinder relies on continuous air pressure to maintain its position; if air is lost or the valve centers, the piston will drift. For positive load holding without live pressure, 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 SE40BX30 FAQ
At 0.5 MPa, the SE40BX30 provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N. The maximum push force is 128 kgf when operated at the 1.0 MPa pressure limit.
This specific SKU does not include a built-in magnet for CMSE or DMSE position sensors. Mechanically, it is a true ISO 15552 profile cylinder with a PT1/4 port, making it a direct replacement for any standard 40 mm bore ISO 15552 cylinder without requiring custom mounting brackets.
