About the Airtac SC50 Standard Cylinder SC50X176S
The SC50X176S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 176 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 with M16x1.5 male threads.
The suffix 'S' denotes a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. With a body length A of 150 mm, the total extended length is approximately 326 mm. The adjustable air cushion (21 mm) decelerates the piston smoothly at stroke ends.

Where the Airtac SC50 Standard Cylinder SC50X176S Is Used
Material Handling & Sorting
The 176 mm stroke and sensor-ready magnet make it ideal for pusher and diverter stations on packaging lines, where mid-stroke position confirmation is required.
Automated Assembly Fixtures
Delivers 982 N of clamping force at standard line pressure, with magnetic sensors verifying clamp engagement before a machining or joining cycle starts.
Laboratory Test Rigs
The built-in magnet enables precise end-of-stroke detection for cycle counting in durability test stands, operating reliably within the standard -20 to +70 °C range.
Is the Airtac SC50 Standard Cylinder SC50X176S the Right Cylinder?
For applications needing slightly more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a lighter, more compact solution is acceptable, the 40 mm bore delivers 628 N at the same pressure. The 176 mm stroke is within the standard range for this bore size.
When replacing this cylinder, match five key points: 50 mm bore, 176 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration. This model uses PT1/4 ports and the standard TPU seals for a temperature range of -20 to +70 °C.
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 SC50X176S 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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The 'S' suffix indicates a built-in magnet is already installed on the piston. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel's tie-rod slots to detect piston position without any modification.
