About the Airtac SC50 Standard Cylinder SC50X315S
The SC50X315S is a double-acting AirTAC SC tie-rod cylinder delivering 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a 315 mm stroke, this model includes a built-in magnet (-S suffix) that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for contactless position sensing.
Its PT1/4 pneumatic ports and M16x1.5 rod thread ensure straightforward integration into standard air circuits. The cylinder body length A is 150 mm, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends of the stroke, reducing impact noise and extending service life in medium-duty automation tasks.

Where the Airtac SC50 Standard Cylinder SC50X315S Is Used
Sensor-Monitored Part Transfer
The built-in magnet enables precise end-of-stroke detection with CMSG/DMSG sensors, making the SC50X315S ideal for pick-and-place or part-transfer stations where the controller must confirm cylinder position before the next sequence step.
Automated Clamping & Fixturing
Delivering up to 1767 N of clamping force at 0.9 MPa, this cylinder reliably secures workpieces in CNC fixtures or welding jigs. The magnetic piston allows sensor feedback to verify the clamp is fully engaged before machining starts.
Pneumatic Gate & Diverter Actuation
With a 315 mm stroke and 982 N of push force at standard line pressure, this cylinder can actuate diverters or gates on material-handling lines. The adjustable cushioning provides smooth, quiet operation at the end of travel, even under moderate loads.
Is the Airtac SC50 Standard Cylinder SC50X315S the Right Cylinder?
Choose the SC50 bore when your application needs around 982 N of push force at 0.5 MPa; if you require significantly more force, step up to the SC63 bore (1559 N at 0.5 MPa), or down to the SC40 (628 N) for a lighter, more compact actuator. The 315 mm stroke is within the 1200 mm maximum standard stroke for this bore, but at this length, ensure the rod is protected from side loads—an external linear guide or a guided cylinder configuration is recommended to prevent rod bending and premature bearing wear.
For a direct replacement, match five critical points: bore (50 mm), stroke (315 mm), port thread (PT1/4), the built-in magnet (-S) for sensor compatibility, and the basic mounting style. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC50X315S FAQ
At the standard operating pressure of 0.7 MPa, the cylinder generates 1374 N of push force and 825 N of pull force. The maximum push force at 0.9 MPa is 1767 N. Always size the cylinder based on the available plant air pressure and a suitable load factor for the application.
Yes. The -S suffix in the model code SC50X315S indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG series sensors directly onto the cylinder barrel's tie-rod slots to detect piston position without any additional mounting brackets.
