About the Airtac SC100 Standard Cylinder SC100X520
The AirTAC SC100X520 is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore, 25 mm diameter piston rod, and a 520 mm stroke, this model is built for demanding linear automation tasks that require significant thrust over a medium distance.
This cylinder features a 29 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, making the total extended length approximately 708 mm. It uses PT1/2 ports and an M20x1.5 rod thread, operating on filtered air within a -20 to +70 °C temperature range with its standard TPU seals.

Where the Airtac SC100 Standard Cylinder SC100X520 Is Used
Pallet Transfer Systems
Provides the high push force needed to transfer heavy pallets or totes between conveyor lines, with the 520 mm stroke covering standard transfer distances.
Heavy-Duty Clamping
Generates up to 7068 N of clamping force for securing large workpieces in CNC machining, welding fixtures, or assembly jigs.
Press and Forming Assist
Delivers consistent, controlled linear force for small pneumatic press operations, bending, or light forming tasks where a 520 mm stroke is needed for part loading.
Is the Airtac SC100 Standard Cylinder SC100X520 the Right Cylinder?
For applications needing slightly less force, consider stepping down to an 80 mm bore SC80 series, which provides 2513 N at 0.5 MPa. If your load requires more thrust, the 125 mm bore SC125 series offers 6136 N at the same pressure. Always ensure the cylinder is sized with a safe margin above the actual moving load.
With a 520 mm stroke, the 25 mm rod has significant unsupported length. Any side loading, even minor, can cause rod bending or premature bearing wear. For this stroke length, it is strongly recommended to use an external linear guide to absorb transverse forces, or to mount the cylinder so the load path is purely axial. To replace an existing unit, match the 100 mm bore, 520 mm stroke, PT1/2 port thread, basic mounting configuration, and confirm whether a magnet is required for sensors.
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 SC100X520 FAQ
The theoretical push force at 0.5 MPa is 3927 N, and at the maximum operating pressure of 0.9 MPa it is 7068 N. The pull force on the retract stroke is 3681 N at 0.5 MPa due to the area taken up by the 25 mm rod. Always apply a safety factor for real-world dynamic loads.
Yes, a 520 mm stroke is non-standard. The maximum standard stroke for the SC100 bore is 1500 mm. While 520 mm is not a listed standard increment, it is within the manufacturable range and can be ordered as a made-to-order item.
