About the Airtac SC100 Standard Cylinder SC100X40SN
The SC100X40SN is a compact-stroke member of the SC tie-rod family, delivering a robust 3927 N push force at 0.5 MPa from a 100 mm bore. Its short 40 mm stroke, combined with a 25 mm diameter piston rod and a 29 mm adjustable air cushion, makes it ideal for clamping, ejecting, and short-transfer tasks where space is tight.
This model is configured with a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG solid-state or reed sensors, and NBR (nitrile) seals (suffix N). The standard PT port thread is 1/2 inch, and the body length A is 188 mm, giving a total extended length of approximately 228 mm.

Where the Airtac SC100 Standard Cylinder SC100X40SN Is Used
High-Force Clamping
The 3927 N push force at 0.5 MPa makes this cylinder ideal for pneumatic clamps and presses in woodworking or metal fabrication, holding workpieces securely during machining.
Short-Stroke Ejection
With a 40 mm stroke, it is perfectly suited for ejecting parts from a conveyor or sorting gate, providing a quick, powerful, and repeatable linear motion.
Sensed End-of-Stroke
The built-in magnet allows for precise electronic end-of-stroke detection via CMSG/DMSG sensors, making it a reliable choice for automated assembly stations requiring cycle confirmation.
Is the Airtac SC100 Standard Cylinder SC100X40SN the Right Cylinder?
Choose the SC100X40SN for high-force, short-stroke applications where position sensing is required. If your force requirement is lower, stepping down to an 80 mm bore reduces push force to 2513 N at 0.5 MPa; for even higher force, the 125 mm bore delivers 6136 N. The built-in magnet allows you to clamp CMSG/DMSG/EMSG sensors directly onto the tie-rod barrel without custom brackets.
For replacement, match five key points: 100 mm bore, 40 mm stroke, PT (1/2 inch) port thread, the built-in magnet (-S), and the NBR seal material. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC100 or an equivalent tie-rod design.
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 SC100X40SN FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It will only be a direct dimensional match for another AirTAC SC100 tie-rod cylinder with identical mounting and port thread.
