About the Airtac SC100 Standard Cylinder SC100X239
The SC100X239 is a double-acting pneumatic cylinder with a 100 mm bore and a 239 mm stroke, built on the proven AirTAC SC tie-rod platform. At 0.5 MPa it generates 3927 N pushing force and 3681 N pulling force, placing it firmly in the heavy-duty automation class for pressing, clamping, and lifting tasks.
This model features a 25 mm diameter piston rod with M20x1.5 threads and a 29 mm adjustable air cushion at each end to decelerate the load smoothly. Because the 239 mm stroke is not a standard catalogue length for the 100 mm bore, this is a non-standard made-to-order configuration. The body length A is 188 mm, giving an approximate extended length of 427 mm.

Where the Airtac SC100 Standard Cylinder SC100X239 Is Used
Pallet Stop & Transfer
The 3927 N push force at 0.5 MPa stops and transfers heavy pallets on roller conveyors, with the 29 mm cushion absorbing impact energy for reliable long-life operation.
Heavy-Duty Clamping
Delivers up to 7068 N at 0.9 MPa for weld-fixture clamping and assembly-press tooling, holding parts rigidly during fabrication cycles.
Bin Diverter Gate
The 239 mm stroke provides sufficient travel to swing a diverter gate in bulk-material handling chutes, directing product flow between two discharge points.
Is the Airtac SC100 Standard Cylinder SC100X239 the Right Cylinder?
Choose the SC100 when your application needs roughly 3900 N of force at standard shop air; if you need less, the SC80 delivers 2513 N at 0.5 MPa, and for more force the SC125 provides 6136 N. For this 239 mm stroke, ensure the rod is not subjected to significant side loading—long unsupported rods can bend under lateral force. If side load is unavoidable, add an external linear guide or switch to a guided cylinder.
To replace an existing cylinder, match five points: 100 mm bore, 239 mm stroke, PT1/2 port thread, basic mounting (no accessory bracket), and no magnet. This 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 SC100X239 FAQ
At 0.5 MPa the theoretical push force is 3927 N and 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. Actual force is slightly lower due to friction.
No. The SC100X239 is a double-acting cylinder and does not lock or hold position when air pressure is exhausted or the directional valve is centered—the piston will drift. If load holding is required, add a pilot-operated check valve or an external mechanical rod brake.
