About the Airtac SC50 Standard Cylinder SC50X240
The SC50X240 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 240 mm stroke. It generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod.
This model features a body length A of 150 mm and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly. The standard PT1/4 ports and M16x1.5 rod thread make it a direct fit for many general automation tasks requiring a mid-range force output.

Where the Airtac SC50 Standard Cylinder SC50X240 Is Used
Part Transfer
Pushes or lifts components between conveyor lines with a controlled 240 mm stroke, using the 982 N force at standard line pressure.
Clamping & Pressing
Applies consistent clamping force in woodworking or light assembly jigs, where the 20 mm rod provides good rigidity for the stroke.
Bin Diverter
Actuates a diverter gate in material handling chutes, with the adjustable cushion reducing noise and vibration at the stroke ends.
Is the Airtac SC50 Standard Cylinder SC50X240 the Right Cylinder?
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N of push force at the same 0.5 MPa pressure. If space is a constraint, the 40 mm bore SC40 delivers 628 N. This 240 mm stroke is well within the 1200 mm maximum standard stroke for the 50 mm bore.
When replacing this cylinder, match five key points: 50 mm bore, 240 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a magnet. For strokes over 300 mm, consider an external guide to protect the rod from bending under side loads, but at 240 mm the standard rod bearing is sufficient for purely axial loads.
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 SC50X240 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 force at 1.0 MPa is 200 kgf.
This specific model code (SC50X240) does not include the '-S' magnet option, so the piston does not have a built-in magnet. To use CMSG or DMSG sensors, you would need the SC50X240-S variant. The standard model requires external limit switches for position sensing.
