About the Airtac SC50 Standard Cylinder SC50X1200STC
The SC50X1200STC delivers 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod. This long 1200 mm stroke model includes a built-in magnet and a centre trunnion mounting system, making it ready for pivoting applications where sensor feedback is required.
With a body length A of 150 mm and a 21 mm adjustable air cushion, this double-acting cylinder decelerates end-of-stroke loads smoothly. The PT1/4 ports and M16x1.5 rod thread ensure straightforward pneumatic connections, while the genuine AirTAC tie-rod construction provides reliable service in demanding industrial environments.

Where the Airtac SC50 Standard Cylinder SC50X1200STC Is Used
Long-Stroke Material Transfer
Pushes or pulls bins and pallets across wide conveyor gaps. The 1200 mm stroke covers large transfer distances, while the trunnion mount allows the cylinder to pivot freely as the load moves.
Automated Welding Fixtures
Clamps large fabricated assemblies with 1767 N of force at 0.9 MPa. The built-in magnet enables end-of-stroke sensor confirmation, ensuring the fixture is fully closed before the welding cycle begins.
Grain Chute Diverter Gates
Operates heavy diverter flaps on silos and processing lines. The centre trunnion mounting allows the entire cylinder body to swing, accommodating the arc motion of the gate without side-loading the rod.
Is the Airtac SC50 Standard Cylinder SC50X1200STC the Right Cylinder?
Select the SC50 when your application needs between 825 N (pull) and 982 N (push) at standard 0.5 MPa shop air. If you require more force, stepping up to the SC63 bore provides 1559 N push at the same pressure. For this 1200 mm stroke, side-load management is critical: the long, unsupported 20 mm rod can bend under lateral forces, so always use an external linear guide or rod-alignment coupler to protect the rod bearing and piston seals.
This model is configured with a magnet (S) for CMSG/DMSG/EMSG sensors and a centre trunnion (TC) mount, which includes the TCM1 bracket (F-SC50TC). When replacing, match five key points: 50 mm bore, 1200 mm stroke, PT port thread, centre trunnion mounting, and the built-in magnet for sensor compatibility.
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 SC50 Standard Cylinder SC50X1200STC FAQ
At the standard 0.5 MPa operating pressure, this 50 mm bore cylinder produces 982 N of push force and 825 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
A 1200 mm stroke with a 20 mm rod is susceptible to buckling under compressive loads and bending from side forces. You must guide the load externally with a linear rail system or use a rod-alignment coupler with a floating joint. Never allow the rod to push a load that is not supported by a separate guide mechanism.
