About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350H
The SC125X350H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, equipped with high-temperature Viton (FKM) seals that shift the operating range to 0–150 °C, making it suitable for autoclaves, foundries, and drying lines. With a 125 mm bore, it generates a push force of 6136 N at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa, driven by a 32 mm piston rod with M27×2 male threads.
At a 350 mm stroke, the extended body length reaches approximately 553 mm (body length A of 203 mm plus stroke). The PT1/2 ports and 28 mm adjustable air cushion provide reliable end-of-stroke deceleration for heavy payloads. As a genuine AirTAC actuator, it is built for demanding industrial automation where heat resistance and robust force output are non-negotiable.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350H Is Used
High-Temperature Pressing
Viton seals allow the SC125X350H to operate continuously at 150 °C, making it ideal for hot-press platens, vulcanizing equipment, and composite curing molds where standard seals would degrade.
Heavy-Duty Clamping
With 11045 N of force at 0.9 MPa, this cylinder delivers the clamping authority needed for large CNC fixture tables, injection mold clamping, and structural welding jigs.
Foundry & Kiln Actuation
The 350 mm stroke and heat-resistant construction suit kiln door lifters, foundry shakeout gates, and glass furnace dampers where ambient temperatures exceed standard pneumatic limits.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350H the Right Cylinder?
Select the SC125 bore when your application requires a push force above 6136 N at standard shop air, a significant step up from the SC100 bore which provides 3927 N at the same 0.5 MPa. If your load is lighter, stepping down to the SC100 reduces air consumption and physical envelope. For strokes of 300 mm or more like this 350 mm unit, the 32 mm rod is susceptible to bending under side load; always guide the load externally with linear rails or rods, or consider a guided cylinder if rigid support cannot be added.
For a drop-in replacement, match five critical points: 125 mm bore, 350 mm stroke, PT port thread, basic (no mounting accessory) configuration, and the absence of a magnet. The SC is a tie-rod design and is dimensionally shorter than an ISO 15552 cylinder, so it is not a direct swap for profile cylinders. Only the 125–250 bore range carries an ISO 6430 class rating.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac AIRTAC SC125-160 Standard Cylinder SC125X350H FAQ
At 0.7 MPa operating pressure, the SC125 bore generates a theoretical push force of 8590 N and a pull force of 5734 N on the retract stroke, accounting for the 32 mm rod area.
No, the AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. The body length A is 203 mm versus a typical ISO 15552 length of 225 mm or more for the same bore. It is not dimensionally interchangeable with ISO 15552 profile cylinders. Match it to another AirTAC SC tie-rod cylinder with identical bore, stroke, PT ports, and no magnet.
