About the Airtac SC100 Standard Cylinder SC100X18S
The AirTAC SC100X18S is a double-acting tie-rod cylinder with a 100 mm bore and a short 18 mm stroke, ideal for compact clamping, ejecting, or positioning tasks. At 0.5 MPa it generates 3927 N push force (3681 N pull), and at the maximum operating pressure of 0.9 MPa the thrust reaches 7068 N.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for contactless end-of-stroke detection. The rod diameter is 25 mm with an M20x1.5 thread, the port is PT1/2, and the adjustable air cushion (29 mm) softens the stop at both ends. Body length A is 188 mm, giving a compact extended length of approximately 206 mm.

Where the Airtac SC100 Standard Cylinder SC100X18S Is Used
Short-Stroke Clamping
The 18 mm stroke and 3927 N force at 0.5 MPa make it a good fit for fixture clamps and press jigs where the jaw travel is minimal but holding force must be high.
Sensor-Controlled Ejection
With the built-in magnet, CMSG/DMSG sensors confirm full retraction and extension, making the SC100X18S suitable for automated part-ejection stations on assembly lines.
Compact Diverter Gate
Use this cylinder to actuate a small diverter flap on a conveyor. The short stroke cycles quickly, and the adjustable cushion reduces impact noise at the end of travel.
Is the Airtac SC100 Standard Cylinder SC100X18S the Right Cylinder?
Choose the SC100 bore when your application needs roughly 4000 N at 0.5 MPa; if you can work with about 2500 N the SC80 (2513 N push at 0.5 MPa) is a lighter, more compact alternative. For higher force step up to the SC125 bore (6136 N at 0.5 MPa).
When replacing an existing cylinder, match five points: 100 mm bore, 18 mm stroke, PT1/2 port thread, the built-in magnet (-S), and the basic mounting style (no bracket). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC100X18S FAQ
At 0.5 MPa (5 bar) 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 reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without mechanical switches.
