About the Airtac SE50 Standard Cylinder SE50AX250SH
The AirTAC SE50AX250SH is a double-acting single-rod ISO 15552 profile cylinder engineered for harsh environments. It delivers a robust 982 N of push force at 0.5 MPa alongside 825 N of retract force, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel design omits external tie rods entirely, yielding a compact, corrosion-resistant body that mounts flush against machine frames without snagging.
Configured with a SUS420J2 stainless steel rod and high-temperature FKM (Viton) seals, this unit reliably operates from -20 to +150 C. The integrated -S magnet supports CMSE reed and DMSE electronic position sensing, while the field-adjustable pneumatic cushioning at both stroke ends allows technicians to fine-tune end-of-travel deceleration for fast-moving 250 mm loads.

Where the Airtac SE50 Standard Cylinder SE50AX250SH Is Used
Thermoform Packaging Press
Drives a 250 mm forming stroke in high-heat packaging lines, utilizing the FKM Viton seals and 982 N push force to mold polymer films without degrading at elevated ambient temperatures.
Chemical Dispense Station
Actuates a metering pump in washdown environments, relying on the SUS420J2 stainless rod to resist chemical corrosion while the DMSE electronic sensor tracks exact fluid volume.
Hot Stamping Ejector
Ejects stamped metal parts from 150 C heated platens, where the field-adjustable air cushions absorb the kinetic energy of the 1374 N high-speed retract cycle to protect tooling.
Is the Airtac SE50 Standard Cylinder SE50AX250SH the Right Cylinder?
If your dynamics demand less force, the SE40X250 delivers 628 N of push at 0.5 MPa; conversely, scaling up to the SE63X250 provides 1559 N for heavier fixtures. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 units, sharing standard mounting hardware and PT1/4 ports. At 250 mm of stroke, the 20 mm rod and M16x1.5 thread handle moderate side loading, but unsupported long strokes still require an external guide to prevent rod-bearing bending. Remember that the adjustable air cushion only decelerates the piston near stroke end; it is not a lock. If your process must hold a load vertically without live air pressure, use a BSE rod lock variant or an external pilot-operated check valve.
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 SE50 Standard Cylinder SE50AX250SH FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with an absolute maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range spans 30-800 mm/s.
Yes, the SE50AX250SH is dimensionally interchangeable per ISO 15552, meaning it shares standard mounting interfaces and hardware with other profile cylinders. However, it does not hold position when air is lost; the adjustable cushion only decelerates the piston near stroke end. For true load holding, consider the BSE rod lock variant.
