Airtac SE32 Standard Cylinder SE32X125H
The AirTAC Airtac SE32 Standard Cylinder SE32X125H is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø32mm bore and 125mm stroke, PT1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE32 Standard Cylinder SE32X125H
The AirTAC SE32X125H is a double-acting, single-rod ISO 15552 profile cylinder engineered for high-temperature pneumatics. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a 12 mm hard-chrome plated rod with an M10x1.25 thread. Because this SKU uses an FKM (Viton) seal instead of standard TPU, its operating range extends from -20 C up to 150 C, making it well-suited for hot environments where standard rubber compounds would quickly degrade.
Built on an extruded aluminum barrel without external tie rods, this compact profile body resists corrosion and mounts flush against machine frames. The field-adjustable pneumatic cushioning at both stroke ends allows technicians to dial in the deceleration of the 125 mm stroke via a setscrew, softening hard end stops without relying on fixed rubber bumpers. Note that this specific configuration omits the built-in magnet, so it cannot directly host CMSE or DMSE electronic position sensors without modification.

Where the Airtac SE32 Standard Cylinder SE32X125H Is Used
Plastic Injection Mold Ejection
Operating near 150C mold heaters, the FKM seal survives ambient heat while providing 402 N of push at 0.5 MPa to eject small plastic parts over a 125 mm stroke.
High-Temp Conveyor Diverter
With its tie-rod-free extruded profile, this cylinder mounts flush to divert packages on heat-treat conveyor lines where standard TPU seals would fail at elevated temperatures.
Lab Drying Oven Door Actuation
The compact 32 mm bore and Viton seal combination reliably automates oven doors up to 150C, utilizing the 27 mm cushion length to prevent slamming at stroke end.
Is the Airtac SE32 Standard Cylinder SE32X125H the Right Cylinder?
If your application requires slightly less thrust, stepping down is not an option at the 32 mm base size, but stepping up to the 40 mm bore yields 628 N of push at 0.5 MPa for heavier payloads. Conversely, if 402 N is too much force or you need a smaller footprint, the 32 mm is the smallest standard SE bore available. Keep in mind that a plain double-acting cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift. For load-holding safety, consider the BSE rod-lock variant. When retrofitting, match the 25 mm standard stroke increments, the PT1/8 port, and the ISO 15552 mounting interface for a seamless drop-in 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 SE32 Standard Cylinder SE32X125H 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 increases to 563 N, with a maximum push of 82 kgf at 1.0 MPa. The operational speed ranges from 30 to 800 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 / VDMA 24562 standards, allowing it to drop into existing mounting hardware. The H suffix indicates an FKM (Viton) seal, extending the operating temperature range up to 150 C for high-heat environments.
