About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1830STC
The AirTAC SC125X1830STC is a double-acting tie-rod cylinder delivering a substantial 6136 N push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. This model features a non-standard 1830 mm stroke, extending beyond the standard 1500 mm limit for the 125 mm bore, making it a made-to-order solution for long linear movements. The 32 mm diameter piston rod and 28 mm adjustable air cushion ensure robust, decelerated end-of-stroke performance.
Equipped with a built-in magnet (-S suffix) and a centre trunnion mount (-TC suffix), this cylinder is ready for pivoting applications with sensor feedback. The magnet allows direct clamping of CMSG/DMSG/EMSG sensors to the barrel for precise position detection, while the TC mount, supplied with the TCM1 bracket (F-SC125TC), supports smooth angular motion. With PT ports and TPU seals, it operates reliably in standard temperatures from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1830STC Is Used
Long-Stroke Material Transfer
The 1830 mm stroke and 11045 N push force move heavy pallets or components across extended distances in conveyor systems, with the trunnion mount allowing the cylinder to pivot freely during the transfer arc.
Pivoting Clamp & Weld Fixtures
The centre trunnion mount and built-in magnet for sensor feedback make this cylinder ideal for heavy-duty welding or clamping fixtures that swing into position, confirming clamp status at both ends of the 1830 mm travel.
Grain Chute or Diverter Gate Actuation
Handles large diverter gates in agricultural processing, where the high force over a long 1830 mm stroke and the pivoting TC mount precisely direct material flow, with sensors confirming the gate's open or closed state.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X1830STC the Right Cylinder?
For applications requiring a pivoting cylinder with position sensing, the SC125X1830STC with its centre trunnion and built-in magnet is a strong candidate. If your force requirement is lower, stepping down to an SC100 bore reduces the push force to 3927 N at 0.5 MPa, while an SC160 bore increases it to 10053 N. This 1830 mm stroke is non-standard; always verify that the long, unsupported 32 mm rod is adequately guided externally to prevent bending under compressive or side loads.
To ensure a correct replacement, match five key specifications: the 125 mm bore, the exact 1830 mm stroke, the PT port thread, the TC centre trunnion mounting accessory, and the -S magnet option for sensor compatibility. This SC model is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders; it replaces another AirTAC SC tie-rod cylinder of the same configuration. For long strokes like this, an external guide rod or a guided cylinder assembly is strongly recommended to protect the rod bearing from side-load damage.
Quick checklist

- ✓ 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 SC125X1830STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 6136 N of push force and 5734 N of pull force. 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 standard maximum stroke for a 125 mm bore SC cylinder is 1500 mm, making this 1830 mm stroke a non-standard, made-to-order item. For any stroke over 300 mm, and especially at this length, the piston rod is susceptible to bending under side loads. You must use an external guide system or support the rod to ensure long service life and prevent damage to the rod bearing.
