About the Airtac SC50 Standard Cylinder SC50X270SH
The SC50X270SH 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 270 mm stroke, it features a 20 mm diameter piston rod with M16x1.5 male threads and an adjustable air cushion length of 21 mm to decelerate end-of-stroke loads.
This variant includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable piston position detection without external brackets. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range from the standard -20–+70 °C to 0–+150 °C, making it suitable for high-temperature or chemically aggressive environments. The body length A is 150 mm, giving a total extended length of approximately 420 mm.

Where the Airtac SC50 Standard Cylinder SC50X270SH Is Used
High-Temperature Process Actuation
With Viton seals rated for 0–150°C, this cylinder is ideal for actuating dampers, valves, or clamps near furnaces, autoclaves, or heated presses where standard seals would degrade.
Sensor-Monitored Assembly
The built-in magnetic piston allows CMSG/DMSG sensors to be clamped directly to the tie-rod barrel, providing clean end-of-stroke or mid-stroke confirmation for automated pick-and-place or joining operations.
Product Sorting & Diverting
Delivering 1767 N of push force at 0.9 MPa, the SC50X270SH can reliably actuate diverters and gates on conveyor lines, even in washdown-adjacent areas where ambient heat is present.
Is the Airtac SC50 Standard Cylinder SC50X270SH the Right Cylinder?
Select the SC50 bore when your application requires between 825 N (pull at 0.5 MPa) and 1767 N (push at 0.9 MPa). If you need more force, step up to the SC63 bore, which provides 1559 N of push at 0.5 MPa. For a lighter, more compact solution, the SC40 bore delivers 628 N at 0.5 MPa. At a 270 mm stroke, ensure the rod is not subjected to high side loads; for unsupported loads, consider an external linear guide or a guided cylinder to prevent rod bending and premature seal wear.
For a direct replacement, match these five points exactly: 50 mm bore, 270 mm stroke, PT (1/4) port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material for high-temperature operation. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC50X270SH FAQ
At the standard 0.5 MPa operating pressure, the push force is 982 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. As a standard double-acting pneumatic cylinder, the SC50X270SH will drift or drop its load if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the stroke end to reduce impact; it is not a locking or holding device. To hold a position without live pressure, you must add an external rod lock or a pilot-operated check valve.
