About the Airtac SC100 Standard Cylinder SC100X490S
The SC100X490S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 490 mm stroke. At 0.5 MPa it generates 3927 N pushing force and 3681 N pulling force, rising to 7068 N push at the maximum operating pressure of 0.9 MPa, making it suitable for medium-to-heavy linear actuation tasks.
This model includes the -S suffix, indicating a built-in magnet embedded in the piston. The magnet allows tool-free mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for precise, non-contact end-of-stroke detection. The rod diameter is 25 mm with an M20x1.5 thread, and the body length A is 188 mm, giving a total extended length of approximately 678 mm.

Where the Airtac SC100 Standard Cylinder SC100X490S Is Used
Automated Press & Clamp
Delivers up to 7068 N of clamping force at 0.9 MPa for holding workpieces during machining, welding, or assembly operations.
Material Handling & Lift
Pushes or lifts heavy bins and pallets on conveyors with 3927 N of force at 0.5 MPa, ideal for diverters and vertical lifts.
Product Sorting Gate
The built-in magnet allows CMSG/DMSG sensors to confirm gate open/closed position, ensuring reliable sortation on high-speed lines.
Is the Airtac SC100 Standard Cylinder SC100X490S the Right Cylinder?
Choose the SC100 bore when your application needs roughly 4000 N of force at standard plant pressure; the next step down is the SC80 (2513 N push at 0.5 MPa) and the next step up is the SC125 (6136 N push at 0.5 MPa). For this 490 mm stroke, be mindful of side loads—an unsupported 25 mm rod at full extension can bend under lateral force. Consider an external linear guide or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 100 mm bore, 490 mm stroke, PT1/2 port thread, the built-in magnet for sensor compatibility (-S), and the basic (footless) mounting style. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 of the same 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 SC100 Standard Cylinder SC100X490S FAQ
At 0.7 MPa (7 bar), the theoretical pushing force is 5497 N. The pulling force on the return stroke is slightly lower due to the 25 mm rod area.
Yes. The -S suffix means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel without any additional brackets or modifications.
