About the Airtac SC50 Standard Cylinder SC50X1200SH
The AirTAC SC50X1200SH is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a long 1200 mm stroke at the maximum standard limit for this bore, it is built for extended linear movements in high-temperature environments.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C, making it suitable for hot or aggressive media. The adjustable air cushion (21 mm) decelerates the piston smoothly at stroke ends, and the PT1/4 port thread ensures standard pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X1200SH Is Used
High-Temperature Process Actuation
Viton seals allow this cylinder to operate reliably in ambient temperatures up to 150°C, making it ideal for actuating dampers, valves, or clamps in ovens, autoclaves, and foundry equipment.
Long-Stroke Material Transfer
The full 1200 mm stroke, combined with 1767 N of push force, is well-suited for pushing or pulling heavy bins, panels, or workpieces across long distances in automated storage and retrieval systems.
Sensor-Monitored Pressing
The built-in magnet (-S) enables end-of-stroke detection with CMSG/DMSG sensors, providing precise position feedback for automated pressing, riveting, or clinching operations in a hot manufacturing cell.
Is the Airtac SC50 Standard Cylinder SC50X1200SH the Right Cylinder?
Select the SC50 bore when your application requires between 982 N (push at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you need higher force, step up to the SC63 bore which provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the SC40 bore offers 628 N at 0.5 MPa. This 1200 mm stroke is at the maximum standard length for the 50 mm bore; for strokes beyond this, a non-standard order is required.
For a stroke of this length, side loads and rod bending are critical considerations. Never subject the 20 mm rod to unguided radial forces at full extension. Use an external linear guide or a guided cylinder to absorb transverse loads and prevent premature rod bearing wear and seal failure. For replacement, match exactly: bore (50 mm), stroke (1200 mm), PT port thread, built-in magnet (-S), and Viton seals (-H).
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 SC50X1200SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. 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.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with a 1200 mm stroke, PT ports, a magnet, and Viton seals.
