About the Airtac SC50 Standard Cylinder SC50X220SH
The SC50X220SH is a double-acting pneumatic 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 and 220 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads for tooling attachment.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG solid-state or reed sensors, enabling precise end-of-stroke detection without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0 to +150 °C, making it suitable for autoclaves, foundries, or hot-process automation where standard TPU seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X220SH Is Used
Hot-Zone Automation
Viton seals allow this cylinder to operate continuously in ambient temperatures up to 150°C, making it ideal for autoclave door actuation, steam-valve control, and material handling inside curing ovens or environmental test chambers.
High-Temperature Part Ejection
With 1767 N of push force at 0.9 MPa and magnetic piston sensing, it reliably ejects hot molded parts or stamped metal components from presses and die-casting machines onto heat-resistant conveyors.
Sensor-Monitored Clamping
The built-in magnet works with CMSG/DMSG sensors to confirm full extension and retraction. This closed-loop feedback is critical for automated welding fixtures and assembly jigs in high-temperature manufacturing cells.
Is the Airtac SC50 Standard Cylinder SC50X220SH the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC40 series provides 628 N push at 0.5 MPa, while stepping up to the 63 mm bore SC63 series increases output to 1559 N at the same pressure. This 220 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore, so it is a standard catalog item.
To ensure a drop-in replacement, match five key specifications: 50 mm bore, 220 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (-H). The SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profiles, so it is not dimensionally interchangeable with those types. For strokes over 300 mm, consider external guides to protect the rod bearing from side loads.
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 SC50X220SH FAQ
At the standard 0.5 MPa operating pressure, the 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.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is a direct dimensional replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, PT ports, magnet option, and Viton seals.
