About the Airtac SC100 Standard Cylinder SC100X320
The SC100X320 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 320 mm stroke. At 0.5 MPa it generates 3927 N of push force and 3681 N on the pull stroke, placing it in the 4 kN class for medium-to-heavy linear actuation tasks.
This model uses a 25 mm diameter piston rod with M20x1.5 threads and PT1/2 ports. The total extended body length is approximately 508 mm (188 mm body length A plus 320 mm stroke). An adjustable air cushion at each end decelerates the piston over a 29 mm cushion length, reducing end-of-stroke impact.

Where the Airtac SC100 Standard Cylinder SC100X320 Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa reliably stops and transfers heavy pallets on roller conveyors, with the 320 mm stroke providing ample reach across wide conveyor beds.
Press & Clamping Fixtures
Delivers 7068 N of clamping force at the maximum 0.9 MPa operating pressure, ideal for holding large workpieces during welding, assembly, or machining operations.
Material Lift & Tilt Mechanism
The 320 mm stroke and 3681 N pull force suit scissor-lift tables or bin tippers, where the cylinder must smoothly raise and lower a heavy load through a defined arc.
Is the Airtac SC100 Standard Cylinder SC100X320 the Right Cylinder?
For applications needing more force, stepping up to the 125 mm bore SC125 series provides 6136 N at 0.5 MPa. If space or weight is a concern, the 80 mm bore SC80 delivers 2513 N at the same pressure. This 320 mm stroke is within the standard range for the 100 mm bore, which supports strokes up to 1500 mm.
At 320 mm of extension, the 25 mm rod is robust, but any significant side loading should be managed with an external guide rail or rod-alignment coupler to prevent bending stress on the rod bearing. When replacing an existing cylinder, match five points: 100 mm bore, 320 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a magnet.
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 SC100X320 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 reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No, the SC100X320 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or drop. For load-holding, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
