About the Airtac SC100 Standard Cylinder SC100X325
The SC100X325 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 3927 N at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 325 mm stroke, it uses a 25 mm diameter piston rod with an M20x1.5 thread, making it well-suited for heavy linear actuation tasks that require a robust rod and high force output.
This model features a body length A of 188 mm, resulting in a total extended length of approximately 513 mm. The cylinder is equipped with an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly, reducing impact and noise. Standard PT1/2 ports and TPU seals with an operating temperature range of -20 to +70 °C complete this configuration.

Where the Airtac SC100 Standard Cylinder SC100X325 Is Used
Pallet Stop and Lift
Provides the high force needed to stop and lift heavy pallets on conveyor lines, with the 325 mm stroke offering sufficient lift height for transfers.
Heavy-Duty Clamping
Delivers up to 7068 N of clamping force at 0.9 MPa for securing large workpieces during machining, welding, or assembly processes.
Bin Diverter Actuation
Powers diverters in gravity or powered chute systems, reliably pushing heavy product flows into different lanes with a controlled, cushioned motion.
Is the Airtac SC100 Standard Cylinder SC100X325 the Right Cylinder?
Select the SC100 when your application needs the force class of 3927 N at 0.5 MPa. If your load requires less force, stepping down to an 80 mm bore reduces the push force to 2513 N at the same pressure, potentially saving on air consumption and space. For higher force demands, the 125 mm bore provides 6136 N at 0.5 MPa.
For this 325 mm stroke, be mindful of side loads. A long, unsupported 25 mm rod can experience bending moments if the load is not guided linearly. For applications with any off-axis force, pair this cylinder with an external guide rail or rod eye to protect the rod bearing and seal. To ensure a correct replacement, match five key points: 100 mm bore, 325 mm stroke, PT1/2 port thread, basic mounting (no bracket), and the absence of a built-in 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 SC100X325 FAQ
At the standard operating pressure of 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.
No, the SC100X325 is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centered. The piston can drift or drop under load. For load holding, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
