About the Airtac SC100 Standard Cylinder SC100X345
The SC100X345 is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and a 25 mm diameter piston rod, it is built for medium-to-heavy industrial linear motion tasks where reliable thrust is critical.
This model has a 345 mm standard stroke, well within the 1500 mm maximum for the SC100 bore. The total extended body length is approximately 533 mm (188 mm body length A plus stroke). It features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact.

Where the Airtac SC100 Standard Cylinder SC100X345 Is Used
Pallet Handling & Logistics
Provides the high force needed for pallet lifts, transfer stations, and conveyor diverters in distribution centers, operating reliably with filtered compressed air.
Heavy-Duty Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding, assembly, or CNC machining operations.
Press & Forming Assist
Suitable as a pneumatic actuator in small presses, bending fixtures, or material forming jigs where a controlled, repeatable linear force is required.
Is the Airtac SC100 Standard Cylinder SC100X345 the Right Cylinder?
Choose the SC100 when your application needs the 3927 N push force class at standard plant air pressure. If your load requires less force, stepping down to an SC80 bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the SC125 bore provides 6136 N at 0.5 MPa.
For this 345 mm stroke, be mindful of side loads. An unsupported rod extending over 300 mm can experience bending stress if the load is not perfectly axial. Use an external guide rail or rod-alignment coupler to protect the rod bearing and seals. When replacing this cylinder, match five points exactly: 100 mm bore, 345 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and no 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 SC100X345 FAQ
At 0.7 MPa operating pressure, the theoretical push force on the extend stroke is 5497 N. The pull force on the retract stroke is 3681 N at 0.5 MPa.
No, this model does not include the -S magnet option. To use CMSG/DMSG/EMSG sensors, order the SC100X345-S variant, which has a built-in piston magnet. Without it, sensors cannot detect the piston position.
