About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115
The SC125X115 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 6136 N at 0.5 MPa (11045 N at the maximum 0.9 MPa operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion are built to manage high-inertia loads, making this 115 mm stroke unit a strong choice for pressing, clamping, and heavy material handling tasks.
With a body length A of 203 mm, the total extended length is approximately 318 mm. This ISO 6430 class cylinder operates on filtered air from 0.15 to 1.0 MPa and uses standard PT ports (PT1/2) with an M27x2 rod thread. The default TPU seals provide a reliable temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115 Is Used
Heavy-Duty Clamping
The 6136 N force at 0.5 MPa securely holds large weldments, engine blocks, or structural assemblies during machining or fabrication.
Pallet Stop & Lift
Deploys with authority to stop or lift heavy pallets on gravity and powered roller conveyors in distribution centers.
Forming & Bending Press
Provides the consistent thrust needed for sheet metal forming, tube bending, or composite press molding operations.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X115 the Right Cylinder?
Select the SC125 when your application requires a push force above 5000 N at standard plant pressure; the next bore down, the SC100, provides 3927 N at 0.5 MPa, while stepping up to the SC160 nearly doubles the available force to 10053 N. For this 115 mm stroke, the standard tie-rod construction handles axial loads well, but any significant side load requires an external guide or a guided cylinder to protect the rod bearing.
When replacing an existing cylinder, match five key points: the 125 mm bore, 115 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. The SC series has a shorter body than an ISO 15552 cylinder, so dimensional interchangeability is limited to another AirTAC SC tie-rod cylinder of the same configuration.
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 SC125X115 FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The SC series is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
