About the Airtac SE32 Standard Cylinder SE32AX25S
The AirTAC SE32AX25S is a double-acting single-rod ISO 15552 profile cylinder engineered for compact, washdown-duty automation. Delivering 402 N of push force at 0.5 MPa, it features a SUS420J2 stainless-steel rod for superior corrosion resistance. The square extruded aluminum barrel eliminates external tie rods, yielding a flush, space-saving profile that mounts cleanly to machine frames while resisting external contamination.
This 32 mm bore unit includes a built-in magnet (-S) for non-contact position sensing with CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends allow you to tune end-of-stroke deceleration, absorbing kinetic energy smoothly rather than relying on a fixed bumper. It operates at speeds of 30-800 mm/s and uses a PT1/8 port paired with an M10x1.25 rod thread.

Where the Airtac SE32 Standard Cylinder SE32AX25S Is Used
Laboratory Dispenser
Drives a 25 mm dosing stroke for reagents in wet lab environments, relying on the SUS420J2 stainless rod to resist chemical corrosion.
Pouch Sealing Press
Applies 402 N of clamping force at 0.5 MPa to close small food packaging pouches, using the adjustable cushion to soften the impact.
PCB Deflash Station
Advances a cutting head for 25 mm travel to trim circuit board edges, tracking position via the built-in magnet and DMSE electronic sensors.
Is the Airtac SE32 Standard Cylinder SE32AX25S the Right Cylinder?
Choose the SE32AX25S when your process requires precise 25 mm movement in damp or corrosive settings, leveraging its 402 N push at 0.5 MPa. If you need greater thrust, the next size up is the 40 mm bore, which provides 628 N of push force. Conversely, if 32 mm is the smallest available standard ISO bore and your load is lighter, you might evaluate non-ISO compact roundspace alternatives. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories. Note that a plain SE cylinder does not hold its position or load when air is lost, exhausted, or the valve is centered—the piston drifts; use a BSE rod lock for secure holding.
For any stroke of 300 mm or more, long unsupported piston rods risk rod-bearing bending under side load; this 25 mm stroke is short enough to avoid that, but always verify guide loads on external mechanisms.
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 SE32 Standard Cylinder SE32AX25S FAQ
At 0.5 MPa, the SE32AX25S provides 402 N of push force and 345 N of pull force. At 0.7 MPa, push increases to 563 N, with a maximum push of 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other standard profile cylinders. However, a plain SE does not hold its load when air is lost or the valve is centered; the piston drifts. The field-adjustable air cushion only decelerates the piston near stroke end and is not a locking mechanism.
