About the Airtac SC50 Standard Cylinder SC50X356S
The AirTAC SC50X356S is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 356 mm stroke, factory-built with a built-in magnet for barrel-mounted sensors. Its 20 mm piston rod and PT1/4 ports handle push forces of 982 N at 0.5 MPa and up to 1767 N at the 0.9 MPa maximum operating pressure, making it a robust mid-bore actuator.
With a body length A of 150 mm and a 21 mm air cushion at each end, the SC50X356S decelerates loads smoothly without metal-to-metal impact. The integrated magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback in automated sequences.

Where the Airtac SC50 Standard Cylinder SC50X356S Is Used
Conveyor Diverter Gate
The 356 mm stroke and 982 N push force at 0.5 MPa operate a wide diverter gate on a packaging conveyor. The built-in magnet enables sensor-confirmed open/closed status for interlocked control.
Automated Clamp & Drill Fixture
Delivers 1767 N of clamping force at 0.9 MPa to hold a workpiece during a CNC drilling cycle. The -S magnet provides a sensor signal to verify the clamp is fully engaged before the spindle starts.
Pallet Layer Transfer
Pushes a layer of boxes 356 mm across a roller bed onto a pallet. The 50 mm bore provides the force needed for a full layer, and the magnetic piston confirms the pusher has fully retracted.
Is the Airtac SC50 Standard Cylinder SC50X356S the Right Cylinder?
Choose the SC50 bore when 0.5 MPa push force around 982 N fits the load; step down to a 40 mm bore (628 N at 0.5 MPa) for lighter, faster-cycling tasks, or move up to a 63 mm bore (1559 N at 0.5 MPa) for heavier work. This 356 mm stroke exceeds the 1200 mm maximum standard stroke for bore 50 and is a made-to-order length.
At 356 mm stroke, the 20 mm rod is relatively slender. For applications with any side load or off-axis force, add an external linear guide or switch to a guided-cylinder assembly to protect the rod bearing and piston seals from bending stress. For a direct replacement, match bore, stroke, PT port thread, the built-in magnet (-S), and the basic mounting configuration.
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 SC50X356S FAQ
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa push reaches 1374 N, and at the 0.9 MPa maximum operating pressure it delivers 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No, the 356 mm stroke is not a standard length for the 50 mm bore (standard strokes stop at 500 mm for bore 32, and 1200 mm for bore 50, but 356 mm is not in the standard list). This is a made-to-order length. You must order the exact SC50X356S code to get the correct stroke with the built-in magnet.
