About the Airtac SC100 Standard Cylinder SC100X390S
The AirTAC SC100X390S is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). Its 100 mm bore and 390 mm stroke suit medium-to-heavy linear actuation tasks where consistent thrust and sensor feedback are both required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly on the tie-rod barrel for non-contact position sensing. The 25 mm diameter piston rod and 29 mm adjustable air cushion provide robust guidance and smooth end-of-stroke deceleration, with a body length of 188 mm plus the 390 mm stroke.

Where the Airtac SC100 Standard Cylinder SC100X390S Is Used
Conveyor Diverter Gates
The 390 mm stroke and 3927 N push force at 0.5 MPa reliably shift medium-weight packages or pallets across conveyor junctions, with the built-in magnet confirming gate position via barrel-mounted sensors.
Press-Fit Assembly Stations
Delivers up to 7068 N at 0.9 MPa for inserting bearings, bushings, or dowels. The adjustable cushion absorbs impact at the end of the 390 mm stroke, protecting tooling and the cylinder.
Automated Pallet Layer Forming
Used in palletising cells to push or align layers of boxes. The -S magnet provides end-of-stroke confirmation to the PLC, ensuring each layer is squared before the next cycle.
Is the Airtac SC100 Standard Cylinder SC100X390S the Right Cylinder?
For higher force, the SC125 bore offers 6136 N at 0.5 MPa; for a lighter, faster actuator, the SC80 bore provides 2513 N. At 390 mm stroke, the rod is well-supported within the standard stroke range, but any side load should be managed with an external guide or linear rail to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 100 mm bore, 390 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC100X390S FAQ
At 0.5 MPa the push force is 3927 N, at 0.7 MPa it is 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix in SC100X390S means a magnet is built into the piston. AirTAC CMSG, DMSG, or EMSG sensors clamp onto the tie-rod barrel without additional brackets, giving you non-contact end-of-stroke or mid-stroke position signals.
