About the Airtac SE40 Standard Cylinder SE40AX70
The AirTAC SE40AX70 is a double-acting single-rod profile cylinder built to the ISO 15552 standard, featuring a 40 mm bore and a 70 mm stroke. It generates 628 N of push force at 0.5 MPa, making it a solid choice for mid-range actuation. The rod is machined from SUS420J2 stainless steel (option A), providing enhanced resistance to corrosion and washdown chemicals compared to standard carbon steel.
This model utilizes a square extruded aluminum barrel without external tie rods, yielding a compact footprint that mounts flush against machine frames. It includes field-adjustable pneumatic cushioning at both ends, allowing technicians to tune the end-of-stroke deceleration via a set screw to eliminate hard mechanical impacts. Note that this specific SKU lacks a built-in magnet, so it is not ready out-of-the-box for CMSE or DMSE position sensing.

Where the Airtac SE40 Standard Cylinder SE40AX70 Is Used
Pouch Sealing Press
Drives the heated sealing jaw on a continuous packaging line, where the SUS420J2 stainless rod withstands routine washdown cycles.
Flighted Conveyor Diverter
Extends 70 mm to push product pouches onto an adjacent packaging lane, utilizing 628 N of push force at 0.5 MPa to overcome carton friction.
Lab Sample Ejector
Ejects processed specimen trays from a testing carousel, benefiting from the smooth adjustable air cushions that protect delicate glassware at stroke end.
Is the Airtac SE40 Standard Cylinder SE40AX70 the Right Cylinder?
Selecting the SE40AX70 is appropriate when your application requires around 628 N of push force at 0.5 MPa. If you need less force, the neighboring 32 mm bore provides 402 N of push; if your load demands more power, stepping up to the 50 mm bore yields 982 N. Because this is a standard ISO 15552 profile cylinder, it serves as a direct dimensional replacement for other ISO 15552 cylinders, utilizing the same PT1/4 port and standard mounting accessories. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; if your process must hold a load safely without live pressure, consider an AirTAC BSE rod lock variant instead.
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 SE40AX70 FAQ
The SE40AX70 has a 40 mm bore and delivers 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 879 N, with a maximum push capacity of 128 kgf at 1.0 MPa. It features a PT1/4 port, a 16 mm rod, and operates at speeds between 30-800 mm/s.
Yes, the SE40AX70 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders, matching the exact mounting interface, port locations, and rod thread size without altering your machine plate.
