About the Airtac SE125 Standard Cylinder SE125X230S
The AirTAC SE125X230S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while maintaining the standardized ISO 15552 footprint.
Equipped with a built-in magnet (-S), this unit seamlessly integrates AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable air cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard impacts when moving massive loads at up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X230S Is Used
Stamping Press Ejection
Provides the 6136 N push force required to knock heavy stamped metal panels out of progressive dies, utilizing the 230 mm stroke to clear the lower die bed entirely.
Injection Mold Separation
Leverages the 125 mm bore's 5734 N pull capacity to break the vacuum seal on large plastic injection molds, while the adjustable cushion softens the retraction impact at high speeds.
Pallet Stopper Actuation
Drives heavy-duty end-of-line pallet stops in high-throughput distribution centers, where the -S magnet triggers DMSE sensors to confirm barrier deployment.
Is the Airtac SE125 Standard Cylinder SE125X230S the Right Cylinder?
Selecting this 125 mm bore is appropriate when applications demand substantial thrust, such as the 8590 N generated at 0.7 MPa. If a smaller footprint is preferred, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa; however, the SE125X230S stands as the largest standard option in this series, offering a maximum push of 1252 kgf at 1.0 MPa. Because this 230 mm stroke is a non-standard made-to-order length, verify lead times during procurement.
As a double-acting cylinder, it relies on continuous air pressure to hold position and will drift if supply is lost—use a BSE rod lock for fail-safe holding. Although the 32 mm rod and M27x2 thread provide excellent rigidity, any stroke exceeding 300 mm necessitates an external guide to prevent rod-bearing bending under high side loads. This model is dimensionally interchangeable with other ISO 15552 cylinders, accepting standard PT1/2 porting and mounting accessories.
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.
