About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225S
The SC160X225S is a double-acting pneumatic cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 225 mm stroke and a robust 40 mm diameter piston rod, it is well-suited for medium-reach clamping, pressing, and lifting tasks in heavy industrial machinery.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for reliable end-of-stroke detection. The adjustable air cushion (29 mm length) decelerates the piston smoothly, reducing impact noise and vibration at the end of each cycle.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225S Is Used
Heavy-Duty Clamping
Generates over 10000 N of force at standard line pressure, ideal for securely holding large workpieces on CNC machining centres and welding fixtures.
Palletising & Sorting Gates
The 225 mm stroke and magnet sensor capability enable precise, high-force actuation of diverter gates and pallet stops in automated logistics lines.
Press-Fit Assembly
Delivers up to 18095 N of push force at 0.9 MPa, providing the controlled power needed for bearing insertion, riveting, and forming operations.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225S the Right Cylinder?
For applications requiring more force, stepping up to the SC200 bore provides 15708 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC125 bore offers 6136 N at the same pressure. Always match replacement cylinders on all five key points: 160 mm bore, 225 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
At a 225 mm stroke, the 40 mm rod is well-supported within the cylinder, but any significant side load in the application should be managed with an external guide or linear rail to prevent rod bending and premature seal 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 SC160X225S FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes. The -S suffix in the model code SC160X225S indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the cylinder's tie-rod barrel for contactless position sensing.
