About the Airtac SE32 Standard Cylinder SE32X125N
The AirTAC SE32X125N is a double-acting, single-rod ISO 15552 profile cylinder with a 32 mm bore and 125 mm stroke. It delivers 402 N of push force at 0.5 MPa and features a robust NBR seal for standard pneumatic duty. The extruded aluminum barrel lacks external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This unit uses a field-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke end. Because this SKU lacks the -S magnet code, it is not wired for CMSE or DMSE position sensing out of the box, relying purely on its mechanical end stops.

Where the Airtac SE32 Standard Cylinder SE32X125N Is Used
CNC Fixture Clamping
Provides 402 N of push force at 0.5 MPa to secure aluminum housings inside CNC machining centers during milling operations.
Carton Flap Folding
Uses the 125 mm stroke to cleanly tuck minor flaps on corrugated cartons before the sealing head applies hot melt adhesive.
Lab Sample Diverting
Actuates a diverter gate in blood-tube sorting racks, benefiting from the compact tie-rod-free profile that resists washdown chemicals.
Is the Airtac SE32 Standard Cylinder SE32X125N the Right Cylinder?
If 402 N push at 0.5 MPa is insufficient, stepping up to the 40 mm bore yields 628 N; conversely, dropping below 32 mm is not standard for the SE line. As a standard double-acting cylinder, the SE32X125N does not hold its load when air pressure is lost or the valve centers—the piston will drift. Use an external pilot-operated check valve or a BSE rod lock for strict position holding. At 125 mm stroke, side-load stress on the M10x1.25 rod bearing is moderate, but an external guide is still recommended for heavy lateral loads.
For ISO 15552 dimensional interchangeability, match the 32 mm bore, 125 mm stroke, PT1/8 port, and basic mounting footprint when retrofitting older machinery.
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 SE32X125N FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force is 563 N. The maximum push force is 82 kgf at 1.0 MPa.
Yes, the SE32X125N is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact same mounting footprint and PT1/8 port sizing as other standard profile cylinders, making it a drop-in retrofit.
