About the Airtac SC100 Standard Cylinder SC100X40SFB
The SC100X40SFB is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 40 mm stroke and 25 mm diameter piston rod, it is built for short, powerful linear movements in compact machine spaces.
This model features a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The FB rear flange (F-SC100FB) provides rigid panel mounting from the cap end, while the standard PT1/2 ports and TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X40SFB Is Used
Short-Stroke Clamping
The 40 mm stroke and 3927 N force are ideal for material clamping fixtures on assembly lines, providing a firm hold without excessive cylinder extension.
Press-Fit Assembly
Delivers a controlled 7068 N punch at 0.9 MPa for pressing bearings or bushings into housings, with sensor feedback confirming cycle completion.
Machine Guard Actuation
The rear flange mount and short stroke suit safety interlock gates or diverter flaps, where a robust, sensor-monitored linear motion is required.
Is the Airtac SC100 Standard Cylinder SC100X40SFB the Right Cylinder?
For applications needing slightly less force in a smaller envelope, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If your stroke requires frequent cycling, ensure the 25 mm rod is adequately guided for side loads. For replacement, match exactly: 100 mm bore, 40 mm stroke, PT1/2 port thread, FB rear flange mounting, and the -S magnet option for sensor compatibility.

- ✓ 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 SC100X40SFB FAQ
At 0.5 MPa (5 bar), the theoretical push force is 3927 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The pull force is slightly lower due to the 25 mm rod area, delivering 3681 N at 0.5 MPa.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
