About the Airtac SC100 Standard Cylinder SC100X312SN
The SC100X312SN is a double-acting AirTAC SC tie-rod cylinder with a 100 mm bore and 312 mm stroke, delivering a push force of 3927 N at 0.5 MPa (up to 7068 N at 0.9 MPa). This model features a 25 mm piston rod, M20x1.5 rod thread, and a 29 mm adjustable air cushion to decelerate the load smoothly at end of travel.
Equipped with a built-in magnet (-S suffix) and NBR seals (-N suffix), this cylinder supports CMSG/DMSG/EMSG sensors for rod-position detection and is suited for general industrial environments. The PT1/2 port and 188 mm body length A keep the footprint compact while handling medium-force clamping, pressing, and positioning tasks.

Where the Airtac SC100 Standard Cylinder SC100X312SN Is Used
Medium-Duty Part Transfer
The 312 mm stroke and 3927 N push force move pallets or fixtures between conveyor stations reliably, with the built-in magnet enabling end-of-stroke sensing for automated sequencing.
Assembly Press & Clamping
Delivers up to 7068 N at 0.9 MPa for pressing bushings or clamping workpieces during welding. The 29 mm air cushion protects tooling from impact damage at high cycle rates.
Automated Sorting Gate
The 100 mm bore provides the force to divert medium-weight packages on a line. NBR seals and the magnetic piston allow reliable sensor feedback in dusty plant conditions.
Is the Airtac SC100 Standard Cylinder SC100X312SN the Right Cylinder?
Choose the SC100 when your application needs roughly 3927 N of push force at standard shop air. If you need a lighter, more compact actuator, step down to the 80 mm bore (2513 N at 0.5 MPa); for heavier loads, the 125 mm bore provides 6136 N at 0.5 MPa. For this 312 mm stroke, ensure side loads are minimal—long unsupported rods can bend under lateral force. Add an external guide or a guided cylinder if the load is not purely axial.
To replace an existing unit, match five points: 100 mm bore, 312 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting style. Always confirm the tie-rod body length A (188 mm) and the M20x1.5 rod thread to guarantee fit.
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 SC100X312SN FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect rod position without additional brackets.
