About the Airtac SC100 Standard Cylinder SC100X300N
The SC100X300N is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 300 mm stroke, it uses a 25 mm diameter piston rod and PT1/2 ports, making it a robust choice for medium-to-heavy industrial linear motion tasks.
This model is fitted with NBR (nitrile) seals as standard, suitable for operating temperatures from -20 to +70 °C. The adjustable air cushion at each end (29 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 488 mm for this configuration.

Where the Airtac SC100 Standard Cylinder SC100X300N Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa reliably raises or stops heavy pallets on gravity or powered roller conveyors in distribution centers.
Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding, assembly, or machining operations.
Material Ejection
Provides a powerful 300 mm stroke to eject heavy parts or scrap from large stamping dies and injection molds.
Is the Airtac SC100 Standard Cylinder SC100X300N the Right Cylinder?
Select the SC100 when your application needs around 4000 N of force at standard shop air pressure; for lighter loads, stepping down to an SC80 bore reduces push force to 2513 N at 0.5 MPa, potentially saving air consumption and cost. For strokes of 300 mm and above, be mindful of side loads—an unsupported 25 mm rod can bend under lateral force, so consider an external guide rail or a guided cylinder if the load is not perfectly axial.
To replace an existing SC100X300N, match five key points: 100 mm bore, 300 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting. 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 SC100X300N 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, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100 is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centered. For load-holding in a power-off or emergency-stop condition, an external pilot-operated check valve or a mechanical rod lock must be added to the circuit.
