About the Airtac SE40 Standard Cylinder SE40BX75
The AirTAC SE40BX75 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 40 mm bore and 75 mm stroke. It leverages a square extruded aluminum barrel that entirely eliminates external tie rods, yielding a compact, flush-mounting body that sheds debris and resists corrosion. Delivering 628 N of push force at 0.5 MPa, this actuator is built specifically for demanding environments via its SUS304 stainless steel piston rod (code B), making it highly suitable for washdown or corrosive-duty applications.
Field-adjustable pneumatic cushioning at both ends allows you to tune end-of-stroke deceleration via a set screw, softening hard mechanical stops during high-speed cycling up to 800 mm/s. Because this specific SKU lacks the built-in magnet option (-S), it does not support direct AirTAC CMSE or DMSE position sensing; if automated end-of-stroke confirmation is required, a magnet-equipped variant would be necessary. The cylinder operates on filtered air at 0.15-1.0 MPa and uses a PT1/4 port.

Where the Airtac SE40 Standard Cylinder SE40BX75 Is Used
Lab Washdown Sorting
The SUS304 stainless rod withstands chemical washdowns in diagnostic equipment sorting lines, using its 628 N push to actuate diverter gates reliably.
Bottle Capping Heads
Drives capping heads on beverage lines where occasional moisture exposure occurs, utilizing the 75 mm stroke and adjustable cushioning to prevent cap deformation.
PCB Panel Ejection
Ejects populated printed circuit boards from test fixtures, benefiting from the tie-rod-free extruded profile that allows flush mounting in dense electronics assembly machinery.
Is the Airtac SE40 Standard Cylinder SE40BX75 the Right Cylinder?
When sizing this 40 mm bore actuator, evaluate your load against its 628 N push at 0.5 MPa. If your application requires less force, stepping down to the 32 mm bore yields 402 N of push, while moving up to the 50 mm bore provides 982 N of push. Remember that a standard SE cylinder relies on live air pressure to maintain position; if air is lost or the directional valve is centered, the piston will drift. For loads that must be held mechanically without continuous pressure, consider the AirTAC BSE rod-lock variant. To retrofit this into an existing machine, match the 40 mm bore, 75 mm stroke, PT1/4 port, and standard ISO 15552 mounting accessories for a direct replacement.
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 SE40BX75 FAQ
The SE40BX75 generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N, with a maximum push capacity of 128 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 standards, allowing it to use shared mounting hardware as a direct replacement for other ISO 15552 profile cylinders. However, this specific SKU lacks the built-in magnet (-S), so it does not support AirTAC CMSE or DMSE electronic position sensors without upgrading to an S-coded variant.
