About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X570S
The SC125X570S is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa, making it a robust choice for heavy linear actuation. This model features a 570 mm stroke with a 32 mm diameter piston rod and M27x2 rod thread, providing substantial column strength for pushing tasks.
A built-in magnet (suffix -S) is integrated into the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for precise end-of-stroke or mid-position sensing. The adjustable pneumatic cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce impact energy at the end caps.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X570S Is Used
Pallet Stop & Transfer
The 6136 N push force at 0.5 MPa reliably stops and transfers heavy pallets on conveyor lines, with the 570 mm stroke providing ample reach across wide roller beds.
Press & Clamping Fixtures
Generates up to 11045 N of clamping force at 0.9 MPa for holding large weldments or composite layups, with the magnetic piston enabling sensor confirmation of clamp engagement.
Baler & Compactor Ejection
The 32 mm rod and high force output eject dense material bales from compaction chambers, while the adjustable cushion absorbs shock at the end of the 570 mm ejection stroke.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X570S the Right Cylinder?
For applications requiring slightly less force, stepping down to the SC100 bore provides 3927 N at 0.5 MPa, while the SC160 bore offers 10053 N at the same pressure for a significant force increase. At a 570 mm stroke, ensure the load is guided and side forces are minimal; long unsupported strokes on a single rod can induce bending moments on the rod bearing. For side-loaded applications, consider an external guide rail or a guided cylinder.
To ensure a correct drop-in replacement, match five key specifications: 125 mm bore, 570 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This is an ISO 6430 class cylinder for the 125 mm bore size.
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 SC125X570S 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.
Yes. The -S suffix in the model code SC125X570S designates a built-in magnet. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position without additional brackets.
