About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125
The AirTAC SC125X125 is a double-acting tie-rod cylinder that delivers 6136 N of 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 125 mm stroke, this model falls within the ISO 6430 class for big-bore cylinders, featuring a robust 32 mm piston rod with an M27x2 thread for secure tooling attachment.
The body length A is 203 mm, giving a total extended length of approximately 328 mm. An adjustable air cushion of 28 mm at each end decelerates the piston smoothly, protecting end caps from impact. Standard PT1/2 ports supply filtered air, and the TPU/NBR seals suit ambient temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125 Is Used
Heavy Press & Clamping
Generates over 11000 N of clamping force at 0.9 MPa, ideal for holding large workpieces during welding, machining, or assembly operations.
Material Handling Gates
The short 125 mm stroke and high force actuate heavy diverter gates or stops on conveyor lines handling pallets or bulk materials.
Agricultural Machinery
Powers lifting and tilting mechanisms on harvesters and spreaders, where the tie-rod design withstands dirty, high-vibration environments.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125 the Right Cylinder?
Choose the SC125X125 when your application needs the high force of a 125 mm bore but a relatively short 125 mm stroke. If you require even greater thrust, step up to the SC160 bore (10053 N at 0.5 MPa); for a lighter, faster actuator, the SC100 bore delivers 3927 N at the same pressure. Always match replacement cylinders on all five critical points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
For strokes of 300 mm or longer, side loads on the rod bearing become a concern—consider an external guide or a guided cylinder. At 125 mm, this standard stroke is well within safe limits for direct axial loads, but any off-axis force should be managed with a rod-end alignment coupler.
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 SC125X125 FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It can directly replace another AirTAC SC125 tie-rod cylinder with the same stroke, port thread, mounting, and magnet option. Only the 125-250 bore range is classed as ISO 6430.
