About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230
The SC125X230 is a double-acting tie-rod cylinder delivering 6136 N push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. With a 125 mm bore and a 230 mm stroke, this model suits medium-stroke clamping, pressing, and heavy-duty linear actuation where a compact tie-rod design is preferred.
Built with a 32 mm diameter piston rod and M27x2 rod thread, the cylinder includes an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly. The body length A is 203 mm, giving a total extended length of approximately 433 mm. This genuine AirTAC SC series unit is factory-lubricated and tested for reliable industrial service.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230 Is Used
Pallet Transfer & Stopping
The 6136 N push force at 0.5 MPa easily stops or transfers heavy pallets on conveyor lines, providing reliable material handling in packaging and logistics centres.
Heavy-Duty Clamping
Ideal for welding jigs and machining fixtures, the 230 mm stroke combined with 11045 N max force securely clamps large fabrications and castings during processing.
Press & Forming Assist
Delivers consistent force for small forming, bending, or assembly press operations where a compact tie-rod cylinder footprint is needed alongside high thrust capability.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X230 the Right Cylinder?
For applications needing more force, stepping up to the SC160 bore provides 10053 N push at 0.5 MPa. If the 230 mm stroke is close to the maximum but a lighter, faster cylinder is acceptable, the SC100 bore (3927 N at 0.5 MPa) may be a more compact alternative. This cylinder is a direct replacement only for another AirTAC SC125 tie-rod cylinder matching bore, stroke, PT1/2 ports, basic mounting, and no magnet. Always confirm the port thread type (PT vs. G) before ordering a replacement.
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 SC125X230 FAQ
At 0.5 MPa air 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 reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter than an equivalent ISO 15552 cylinder, so it is not dimensionally interchangeable. It can only replace another AirTAC SC125 tie-rod cylinder with the same bore, stroke, port thread, and mounting configuration. The 125 mm bore is classified under ISO 6430.
