About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350
The AirTAC SC125X350 is a heavy-duty double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. Its 32 mm diameter piston rod and 28 mm adjustable air cushion are built to manage substantial inertial loads in industrial automation.
With a 350 mm stroke and a body length A of 203 mm, this ISO 6430 class cylinder provides a robust linear motion solution. The standard PT1/2 ports ensure straightforward pneumatic connections, and the TPU seals offer reliable operation within a -20 to +70 C temperature range.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350 Is Used
Palletizing and Depalletizing
The high force output and 350 mm stroke make this cylinder ideal for lifting and placing heavy pallets or slip sheets in automated end-of-line packaging systems.
Heavy-Gauge Material Clamping
Delivers the consistent, high clamping force needed to secure large weldments or thick steel plates during CNC machining or robotic welding, preventing workpiece shift.
Logistics Sortation Pusher
Provides the powerful, long-stroke push required to divert heavy parcels or tires off a main conveyor line onto a spur, operating reliably in dusty warehouse environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X350 the Right Cylinder?
For applications requiring less force, consider stepping down to the SC100 bore, which provides 3927 N at 0.5 MPa. For a higher thrust capacity, the SC160 bore offers 10053 N at the same pressure. The 350 mm stroke on this 32 mm rod is substantial; ensure side loads are minimized or use an external guide system to prevent rod bearing damage and bending.
When replacing an existing cylinder, confirm five key points for a direct match: 125 mm bore, 350 mm stroke, PT1/2 port thread, the specific mounting accessory (this is a basic model without brackets), and the absence of a built-in magnet. This ensures identical form, fit, and function.
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 SC125X350 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 AirTAC SC series is a tie-rod cylinder and is shorter in overall length than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 types. For replacement, match it with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port configuration.
