About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X410S
The SC125X410-S is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at the 0.9 MPa maximum operating pressure). Its 32 mm diameter piston rod and 28 mm adjustable air cushion handle heavy mid-stroke actuation with controlled end-of-travel deceleration.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the tie-rod barrel for reliable, non-contact position sensing. The 410 mm stroke is well within the 1500 mm maximum standard stroke for the 125 mm bore, making it a standard stocked configuration.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X410S Is Used
Heavy Part Transfer
Moves large castings or weldments between machining stations, using the 6136 N push force at 0.5 MPa and sensor-confirmed end-of-stroke signals.
Pallet Stop & Lift
Acts as a robust pallet stop or lift-and-locate unit on heavy-duty conveyor lines, with the built-in magnet enabling precise position feedback to the PLC.
Press & Clamp Actuation
Provides the high clamping force for industrial presses or welding fixtures, where the 11045 N maximum thrust securely holds large workpieces during the cycle.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X410S the Right Cylinder?
For applications needing more force, stepping up to the 160 mm bore provides 10053 N at 0.5 MPa. If a lighter, more compact solution is acceptable, the 100 mm bore delivers 3927 N at the same pressure. Always match replacement cylinders on five points: bore (125 mm), stroke (410 mm), PT port thread, the built-in magnet (-S), and basic mounting.
With a 410 mm stroke, ensure the rod is not subjected to significant side loads. Long, unsupported strokes can create a bending moment on the rod bearing. If the load is not guided externally, consider adding an external linear guide or switching to a guided cylinder to protect the rod and seals from premature wear.
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 SC125X410S FAQ
At 0.5 MPa, 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
Yes. The -S suffix indicates a built-in magnet, making it fully compatible with AirTAC CMSG, DMSG, and EMSG series sensors. These sensors mount externally on the tie-rods to detect piston position without any modification to the cylinder body.
