About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600
The SC125X600 is a heavy-duty double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa, rising to 11045 N at the maximum operating pressure of 0.9 MPa. With a 600 mm stroke and a robust 32 mm piston rod, this model is built for demanding industrial linear motion tasks where substantial force and a mid-range stroke are required.
This genuine AirTAC SC series cylinder features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 203 mm, giving a total extended length of approximately 803 mm. It uses a PT1/2 port and an M27x2 rod thread, operating reliably on filtered air at pressures from 0.15 to 1.0 MPa.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600 Is Used
Palletizer Pushers
The 600 mm stroke and 6136 N push force at 0.5 MPa are ideal for transferring heavy pallets or bulk product layers onto conveyor lines in automated palletizing cells.
Heavy-Gauge Forming Presses
Delivers the high force needed for clamping and forming thick metal or composite sheets, with the adjustable air cushion protecting tooling from impact damage during high-cycle operation.
Wastewater Screen Actuation
Provides reliable, high-force linear motion to lift and lower heavy bar screens or sludge gates in treatment plants, operating consistently in wet and demanding environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X600 the Right Cylinder?
Select the SC125 bore when your application needs force in the 6136 N (at 0.5 MPa) class. If your load requires less force, stepping down to the SC100 bore provides 3927 N at the same pressure, which may reduce air consumption and physical size. For higher force demands, the SC160 bore offers 10053 N at 0.5 MPa.
For this 600 mm stroke, be mindful of side loading. The 32 mm rod is strong, but long unsupported strokes can create a bending moment under lateral forces. Use an external guide rail or rod alignment coupler to protect the rod bearing and ensure a long service life. When replacing, match exactly: 125 mm bore, 600 mm stroke, PT port thread, basic mounting, and the optional magnet if your original unit had the -S suffix.
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 SC125X600 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 tie-rod cylinder that is shorter in overall length than a standard ISO 15552 profile cylinder, so the mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC125 tie-rod cylinder with matching stroke, port type, and mounting configuration.
