About the Airtac SC50 Standard Cylinder SC50X350S
The SC50X350S is a double-acting tie-rod cylinder with a 50 mm bore, 350 mm stroke, and a built-in magnet for barrel-mounted sensors. At 0.5 MPa it generates 982 N extending and 825 N retracting, while the maximum operating thrust at 0.9 MPa reaches 1767 N — a solid mid-range force class for clamping, pressing, and material-transfer tasks.
This model includes the -S magnet suffix, allowing CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The 20 mm diameter rod, PT1/4 ports, and 21 mm adjustable air cushion are standard for the 50 mm bore. With a body length A of 150 mm, the total extended length is approximately 500 mm.

Where the Airtac SC50 Standard Cylinder SC50X350S Is Used
Conveyor Diverter Gate
The 350 mm stroke and 982 N push force at 0.5 MPa reliably actuates a diverter gate or flipper on a packaging line. The built-in magnet lets CMSG sensors confirm gate position at each end of travel.
Assembly Press Fixture
Delivers up to 1767 N at 0.9 MPa for pressing bushings, bearings, or pins into housings. The adjustable air cushion softens the impact at full extension, protecting the fixture and part.
Pallet Stop & Release
A mid-stroke pallet stop in a gravity conveyor lane. The 350 mm throw provides ample retraction clearance, and the magnetic piston allows end-of-stroke sensing to sequence with upstream automation.
Is the Airtac SC50 Standard Cylinder SC50X350S the Right Cylinder?
Choose the SC50 bore when your application needs between 982 N and 1767 N of push force at typical shop air pressures. If you require more force, stepping up to the SC63 bore delivers 1559 N at 0.5 MPa; for a lighter, more compact solution the SC40 bore provides 628 N. At a 350 mm stroke, ensure the rod is not subjected to significant side loading — long unsupported strokes on a 20 mm rod can bend under lateral force; use an external linear guide or a guided cylinder if the load is not purely axial.
For a direct replacement, match five points: 50 mm bore, 350 mm stroke, PT1/4 port thread, the -S magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X350S FAQ
At 0.5 MPa the push force is 982 N and the pull force is 825 N. At 0.7 MPa push force increases to 1374 N, and at the maximum operating pressure of 0.9 MPa it reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in SC50X350S means a magnet is built into the piston, so AirTAC CMSG, DMSG, or EMSG sensors clamp directly onto the tie-rod barrel. A standard SC50X350 without the -S does not support barrel-mounted sensors.
