About the Airtac SC50 Standard Cylinder SC50X400SH
The SC50X400SH 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 400 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-duty linear tasks requiring a balance of force and reach.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The 'H' suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it a reliable choice for high-temperature or chemically aggressive environments where standard seals would degrade.

Where the Airtac SC50 Standard Cylinder SC50X400SH Is Used
High-Temperature Actuation
Viton seals enable reliable operation in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150°C, with 1767 N of force for pressing or ejecting.
Sensor-Controlled Sorting
The built-in magnet allows CMSG/DMSG sensors to confirm extend and retract positions, ideal for automated sortation gates and diverter arms requiring 400 mm of linear travel.
Chemical Process Valves
FKM seals resist aggressive chemicals, making this 50 mm bore cylinder suitable for actuating valves or dispensing heads in chemical dosing and industrial washing systems.
Is the Airtac SC50 Standard Cylinder SC50X400SH the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. For lighter, more compact installations, the 40 mm bore offers 628 N. At a 400 mm stroke, ensure the rod is not subjected to significant side loads; if lateral forces are present, an external linear guide should be used to prevent rod bending and premature seal wear. When replacing, match the 50 mm bore, 400 mm stroke, PT port thread, built-in magnet, and Viton seal material to ensure identical performance.
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 SC50X400SH FAQ
At 0.7 MPa operating pressure, the SC50X400SH produces a theoretical push force of 1374 N. The maximum push force at 0.9 MPa is 1767 N.
No. As a standard double-acting cylinder, the SC50X400SH will not hold its position if air pressure is exhausted or lost. The piston can drift. For load-holding safety, an external rod lock, brake, or a pilot-operated check valve must be added to the circuit.
