About the Airtac SC50 Standard Cylinder SC50X30SH
The SC50X30SH is a compact-stroke double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). With a 30 mm stroke and a 20 mm diameter piston rod, it suits short, fast clamping and ejecting tasks where space is tight.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The -H suffix upgrades the seals to Viton (FKM), shifting the operating temperature range to 0–150 °C for reliable cycling in hot environments.

Where the Airtac SC50 Standard Cylinder SC50X30SH Is Used
Hot Clamping Fixtures
The Viton seals withstand 0–150 °C, making this cylinder ideal for clamping parts in heated presses, thermoforming tools, or soldering jigs where standard seals would degrade.
Sensor-Controlled Ejection
The built-in magnet allows CMSG/DMSG sensors to confirm full retraction and extension during high-speed ejector strokes, preventing machine crashes in automated assembly cells.
Autoclave Door Actuation
With a short 30 mm throw and FKM seals resistant to steam and aggressive cleaning agents, this cylinder reliably operates small autoclave or sterilizer door interlocks.
Is the Airtac SC50 Standard Cylinder SC50X30SH the Right Cylinder?
For a 50 mm bore, the SC50X30SH provides 982 N at 0.5 MPa. If you need more force, stepping up to an SC63 (1559 N at 0.5 MPa) adds capacity; for less, an SC40 (628 N) may reduce air consumption. The short 30 mm stroke keeps the extended length compact at roughly 180 mm (body length A of 150 mm + stroke).
To ensure a direct replacement, match five points: 50 mm bore, 30 mm stroke, PT port thread, the -S magnet for sensor mounting, and the -H Viton seal for high-temperature compatibility. This cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC50X30SH FAQ
At the standard operating pressure of 0.5 MPa, 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.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC tie-rod cylinder matching the 50 mm bore, 30 mm stroke, PT ports, magnet, and Viton seals.
