About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130STC
The SC125X130STC is a double-acting pneumatic 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 130 mm stroke, this model is built on a robust tie-rod construction that is shorter than an equivalent ISO 15552 cylinder, making it a space-efficient choice for heavy linear actuation.
This specific configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC125TC) for pivoting applications. The 32 mm piston rod and 28 mm adjustable air cushion ensure smooth deceleration of large inertial loads, while the standard PT1/2 ports and TPU seals suit general industrial environments from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130STC Is Used
Heavy Part Transfer
The 6136 N push force at 0.5 MPa easily shifts large steel fabrications or heavy castings between conveyor stations, with the trunnion mount allowing the cylinder to pivot as the load transfers.
Clamping & Pressing
Delivering up to 11045 N at 0.9 MPa, this cylinder provides the high force needed for hydraulic-style clamping in welding jigs or assembly presses, with sensor feedback confirming full clamp engagement.
Pivoting Machinery Linkage
The centre trunnion mount (TC) with TCM1 bracket is ideal for actuating a pivoting arm or lever on heavy machinery, absorbing the arc motion without side-loading the rod bearings.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X130STC the Right Cylinder?
Select the SC125 when your application requires push forces in the 6136 N (at 0.5 MPa) to 11045 N (at 0.9 MPa) range. For a step down in force, the SC100 bore provides 3927 N at 0.5 MPa in a lighter package; for higher demands, the SC160 bore delivers 10053 N at the same pressure. This 130 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
To ensure a correct replacement, match five key points: 125 mm bore, 130 mm stroke, PT1/2 port thread, centre trunnion (TC) mounting with the F-SC125TC bracket, and the built-in magnet (-S) for sensors. As an ISO 6430 class tie-rod cylinder, the SC125 is dimensionally distinct from ISO 15552 profile cylinders and will only interchange with another AirTAC SC125 of identical configuration.
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 SC125X130STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 6136 N and the pull force on retraction is 5734 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 11045 N. The theoretical maximum force at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. You must replace it with another AirTAC SC125 cylinder matching the 130 mm stroke, PT1/2 ports, centre trunnion mount (TC), and built-in magnet (-S) to guarantee correct fit and sensor function.
