About the Airtac SC100 Standard Cylinder SC100X400SN
The SC100X400SN is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa operating pressure. Its 100 mm bore and 400 mm stroke suit medium-to-heavy linear actuation tasks, with a 25 mm piston rod and PT1/2 ports providing robust air flow.
This model includes a built-in magnet (-S suffix) so CMSG/DMSG/EMSG reed or solid-state sensors can be clamped directly onto the tie-rod barrel for non-contact position sensing. The NBR seal (-N) offers reliable performance across the standard -20 to +70 °C range, and the adjustable air cushion at each end (29 mm cushion length) decelerates the piston smoothly.

Where the Airtac SC100 Standard Cylinder SC100X400SN Is Used
Conveyor Diverting
The 3927 N push force at 0.5 MPa reliably actuates heavy diverters and gates on wide conveyor lines, with the 400 mm stroke providing ample reach across the belt.
Press Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces in CNC machining centres or welding fixtures, with sensor feedback confirming jaw position.
Pallet Lift & Transfer
The 400 mm stroke lifts or shifts pallets in automated storage systems, and the built-in magnet allows end-of-stroke detection to sequence the next machine cycle.
Is the Airtac SC100 Standard Cylinder SC100X400SN the Right Cylinder?
Choose the SC100 when your load needs the 3927 N push force at 0.5 MPa this 100 mm bore provides. If your force requirement is lower, stepping down to the 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher forces, the 125 mm bore offers 6136 N at the same pressure.
At a 400 mm stroke, ensure the rod is protected from side loads. Long unsupported strokes can create a bending moment on the 25 mm rod; use an external linear guide or a guided cylinder if lateral forces are present. For replacement, match five points exactly: 100 mm bore, 400 mm stroke, PT port thread, NBR seal material, and the built-in magnet for sensor compatibility.
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 SC100 Standard Cylinder SC100X400SN FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix indicates a built-in magnet, making it compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that mount directly on the cylinder's tie rods for precise position detection.
