About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175S
The SC125X175S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 125 mm bore with a 175 mm stroke and a built-in magnet for sensor mounting. At 0.5 MPa it generates 6136 N pushing and 5734 N pulling force, placing it in the heavy-duty class for industrial automation.
This model features a 32 mm piston rod with M27x2 male threads, PT1/2 ports, and a 28 mm adjustable air cushion at each end. The integrated magnet allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection without external brackets.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175S Is Used
Heavy Press & Clamping
With 6136 N push at 0.5 MPa, the SC125X175S applies consistent clamping force in assembly presses, gluing fixtures, and welding jigs where magnetic piston sensing confirms tool position.
Palletising & Material Handling
The 175 mm stroke and 5734 N pull force suit pallet lifters and transfer stations. The built-in magnet enables sensor-based sequencing with upstream conveyors.
Die Cushion & Forming
In metal forming or thermoforming, the adjustable 28 mm cushion absorbs die-impact energy at stroke end, while the magnet provides a clean signal for cycle counting and safety interlocks.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X175S the Right Cylinder?
Choose the SC125 bore when your application needs roughly 6100 N of push force at standard shop air; if you can accept around 3900 N the SC100 bore reduces air consumption and physical size. For strokes of 300 mm or longer, check side-load alignment carefully—the 32 mm rod can bend under off-axis forces, and an external guide or guided cylinder is recommended.
To replace an existing cylinder, match five points: 125 mm bore, 175 mm stroke, PT port thread, basic (no bracket) mounting, and the -S magnet option for sensor compatibility. The SC is a tie-rod design, not an ISO 15552 profile, so it is dimensionally shorter and not interchangeable with ISO 15552 cylinders.
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 SC125X175S FAQ
At 0.5 MPa the cylinder produces 6136 N extending and 5734 N retracting. At the maximum operating pressure of 0.9 MPa, thrust rises to 11045 N push and 10321 N pull. The theoretical force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 cylinder of the same bore and stroke. It only directly replaces another AirTAC SC tie-rod cylinder with matching bore, stroke, PT ports, basic mount, and -S magnet option.
