About the Airtac SC50 Standard Cylinder SC50X320SH
The AirTAC SC50X320SH is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. Its 320 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore, making it a standard-configuration actuator for medium-reach linear tasks.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and high-temperature Viton seals (-H suffix) that shift the operating range from the standard -20–70°C up to 0–150°C. The 20 mm diameter piston rod and M16x1.5 rod thread provide robust connection strength, while the 21 mm adjustable air cushion at each end decelerates the piston quietly.

Where the Airtac SC50 Standard Cylinder SC50X320SH Is Used
High-Temperature Gate Actuation
With Viton seals rated for 0–150°C, this cylinder reliably operates hot gas diverters, oven doors, or foundry gates where standard seals would degrade, providing consistent 1767 N closing force.
Sensor-Monitored Part Transfer
The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the tie-rod barrel, giving end-of-stroke confirmation for a 320 mm transfer station moving medium-weight components on an assembly line.
Heated Press Jig Actuation
Delivers a controlled 320 mm stroke in heated laminating or forming jigs. The 20 mm rod resists buckling under the 1767 N maximum push, while Viton seals maintain integrity in sustained thermal cycling.
Is the Airtac SC50 Standard Cylinder SC50X320SH the Right Cylinder?
Select the SC50 bore when your application needs between 628 N (SC40 push force at 0.5 MPa) and 982 N (SC50 push force at 0.5 MPa). If your load exceeds 982 N at 0.5 MPa, step up to the SC63 bore which provides 1559 N. For this 320 mm stroke, ensure the rod is not subjected to direct side loading; long unsupported strokes can create a bending moment on the rod bearing. If side loads are unavoidable, pair the cylinder with an external linear guide or switch to a guided cylinder unit.
To replace an existing SC50X320SH, match five points exactly: 50 mm bore, 320 mm stroke, PT port thread, the built-in magnet 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.
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 SC50X320SH FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 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 cylinder of the same bore and stroke. It is only a direct dimensional match for another AirTAC SC tie-rod cylinder with identical bore, stroke, PT ports, magnet option, and Viton seals.
