About the Airtac SC50 Standard Cylinder SC50X240S
The SC50X240S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa operating pressure. Its 20 mm diameter piston rod and 150 mm body length A provide a compact yet robust package for mid-range linear motion tasks, with a 240 mm stroke suited to clamping, pressing, and material-transfer operations.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the tie-rod barrel for non-contact position sensing. The adjustable air cushion at each end decelerates the piston smoothly, extending service life in high-cycle applications.

Where the Airtac SC50 Standard Cylinder SC50X240S Is Used
Conveyor Diverter Gates
The 240 mm stroke and 982 N push force reliably actuate diverter gates in packaging and sortation lines, with the magnetic piston enabling end-of-stroke confirmation.
Pneumatic Clamping Fixtures
Delivers consistent clamping force for woodworking or metal fabrication jigs. The built-in magnet simplifies sensor integration for automated clamp/unclamp verification.
Automated Assembly Stations
Used in pick-and-place and pressing operations where mid-stroke position sensing via CMSG/DMSG sensors ensures precise part insertion and cycle control.
Is the Airtac SC50 Standard Cylinder SC50X240S the Right Cylinder?
Select the SC50 bore for push forces around 982 N at standard plant air; step up to the SC63 (1559 N at 0.5 MPa) if your load exceeds 800 N with a safety margin, or down to the SC40 (628 N) for lighter, faster-cycling tasks. The 240 mm stroke is within the 1200 mm maximum standard stroke for this bore.
For a drop-in replacement, match five attributes: 50 mm bore, 240 mm stroke, PT1/4 port thread, the built-in magnet (-S), and basic mounting. If side loads are present, consider an external guide or a guided cylinder, as the rod bearing is not designed to absorb lateral forces.
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 SC50X240S FAQ
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the tie-rod barrel for position detection.
