About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600SH
The AirTAC SC125X600SH is a rugged tie-rod cylinder built for high-temperature service, delivering 6136 N of push force at 0.5 MPa and 11045 N at the maximum operating pressure of 0.9 MPa. Its 32 mm piston rod and 28 mm adjustable air cushion handle heavy mid-stroke loads with controlled deceleration.
This model is configured with Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for autoclaves, foundries, and drying lines where standard seals would degrade. The 600 mm stroke sits well within the 1500 mm maximum standard stroke for the 125 mm bore, and the PT1/2 port threads match common industrial plumbing.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600SH Is Used
High-Temperature Clamping
With Viton seals rated to 150 °C, this cylinder reliably powers clamps and presses in autoclaves, heated platen presses, and composite curing ovens where heat destroys standard seals.
Heavy Part Ejection
The 11045 N thrust at 0.9 MPa ejects large castings or stampings from dies. The 28 mm adjustable cushion absorbs the impact of the heavy tooling at the end of the 600 mm stroke.
Pallet Transfer & Lift
Used in pallet-handling systems to lift and transfer heavy loads. The 32 mm rod resists bending under high axial force, and the tie-rod construction allows easy maintenance in dusty environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600SH the Right Cylinder?
Choose the SC125 when your application needs 5000–11000 N of force; for lighter loads around 3900 N, stepping down to the SC100 bore (3927 N at 0.5 MPa) can reduce air consumption and physical size. At 600 mm of stroke, the rod is fully supported by the front bearing, but any side load must be managed with an external linear guide—the rod bearing alone is not designed to carry transverse forces.
To replace an existing cylinder, match five points: 125 mm bore, 600 mm stroke, PT port thread, basic (no accessory) mounting, and the absence of a magnet. This is a genuine AirTAC SC series tie-rod cylinder, which is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC125X600SH FAQ
At 0.5 MPa air pressure, the cylinder produces 6136 N pushing and 5734 N pulling. At the maximum operating pressure of 0.9 MPa, the push force rises to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC125 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external rod brake.
