About the Airtac SC50 Standard Cylinder SC50X40S
The SC50X40S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore, 20 mm piston rod, and a compact 40 mm stroke, this model is built for short, repetitive linear movements in automated machinery.
This variant includes a factory-installed magnet (suffix -S) along the piston, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection. The body length A is 150 mm, and the total extended length is approximately 190 mm, making it a space-efficient choice for sensor-equipped applications.

Where the Airtac SC50 Standard Cylinder SC50X40S Is Used
Packaging Line Diverter
Short 40 mm stroke with magnetic piston sensing confirms product divert gates have fully extended or retracted on high-speed packaging conveyors.
Automated Clamping Fixture
Provides 982 N of clamping force at standard line pressure, with sensors verifying clamp engagement before a CNC machining cycle begins.
Sortation Gate Actuator
Compact tie-rod cylinder with built-in magnet for end-of-stroke feedback, ideal for actuating small sortation gates in logistics hubs.
Is the Airtac SC50 Standard Cylinder SC50X40S the Right Cylinder?
The SC50X40S suits applications needing moderate force with integrated position sensing. If your load requires more thrust, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa; for lighter, faster cycles, the 40 mm bore offers 628 N. The 40 mm stroke is well within the standard range, ensuring fast availability.
For replacement, match five key points: 50 mm bore, 40 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your required mounting accessory (this model is basic, without brackets). Always verify that the replacement cylinder matches the original's sensor type and mounting footprint.
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 SC50X40S FAQ
At 0.7 MPa operating pressure, the theoretical push force is 1374 N and the pull force is 825 N. The maximum force at 0.9 MPa is 1767 N push.
Yes. The -S suffix indicates a built-in magnet. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without external brackets.
