About the Airtac SC50 Standard Cylinder SC50X150STC
The SC50X150STC is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. Its 150 mm stroke is paired with a 20 mm diameter piston rod and an adjustable air cushion of 21 mm, providing reliable deceleration for mid-range linear tasks.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion pivot (suffix -TC) supplied with the TCM1 bracket (F-SC50TC). The trunnion mount allows the cylinder to swing, making it ideal for pivoting applications. Operating on filtered air from 0.15-1.0 MPa, the standard TPU seals suit a temperature range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X150STC Is Used
Part Diverter Gates
The 150 mm stroke and trunnion mount allow this cylinder to pivot a diverter gate on a conveyor line, sorting packages by size or destination with 1374 N of force at standard line pressure.
Clamping Fixtures
Ideal for swing-clamp operations in machining centres. The centre trunnion allows the arm to rotate clear of the workpiece, while the magnetic piston confirms clamp engagement via a CMSG sensor.
Hopper Door Actuation
Controls a discharge door on a seed or grain hopper. The pivoting action matches the door's arc, and the 1767 N max force handles sticky or bridged materials.
Is the Airtac SC50 Standard Cylinder SC50X150STC the Right Cylinder?
For applications requiring less force, consider stepping down to the 40 mm bore (628 N at 0.5 MPa). If you need more power, the 63 mm bore offers 1559 N at the same pressure. Always ensure the load is guided externally if side forces are present, as the rod bearing is designed for axial loads.
When replacing an existing cylinder, match these five points exactly: 50 mm bore, 150 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This ensures a direct, drop-in fit for another AirTAC SC series tie-rod cylinder.

- ✓ 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 SC50X150STC FAQ
At 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. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix denotes a built-in magnet on the piston. You can clamp an AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensor directly onto the barrel's sensor groove to detect piston position without any additional brackets.
