About the Airtac SC100 Standard Cylinder SC100X780
The SC100X780 is a double-acting pneumatic 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. Its 100 mm bore and 780 mm stroke make it a robust linear actuator for medium-to-heavy industrial tasks, with a 25 mm diameter piston rod providing the rigidity needed for consistent, powerful motion.
This model features a body length of 188 mm and an adjustable air cushion of 29 mm at each end to decelerate the piston smoothly, reducing end-of-stroke impact. Equipped with standard PT1/2 ports and TPU seals for an operating range of -20 to +70 C, it is a genuine AirTAC tie-rod cylinder, engineered for reliable service in demanding automation environments.

Where the Airtac SC100 Standard Cylinder SC100X780 Is Used
Pallet Transfer Systems
The 780 mm stroke and 3927 N push force at 0.5 MPa efficiently transfer heavy pallets between conveyor lines, providing a long, smooth, and powerful linear motion for material handling.
Heavy-Duty Clamping Fixtures
With up to 7068 N of force at 0.9 MPa, this cylinder delivers the high clamping pressure needed to secure large workpieces during machining, welding, or assembly processes.
Large Part Ejectors
Ideal for ejecting finished parts or scrap from large-scale forming presses, the SC100X780 combines a long reach with the robust force to handle substantial loads reliably.
Is the Airtac SC100 Standard Cylinder SC100X780 the Right Cylinder?
Select the SC100X780 when your application requires the force of a 100 mm bore over a 780 mm working distance. For a step down in force, the 80 mm bore (SC80 series) provides 2513 N at 0.5 MPa in a more compact body; for higher force demands, the SC125 series offers 6136 N at the same pressure. With a stroke of 780 mm, ensure the rod is guarded against side loading—consider an external linear guide or a guided cylinder if lateral forces are present, as long, unsupported rods are susceptible to bending.
For a direct replacement, match five critical points: the 100 mm bore, the 780 mm stroke, the PT1/2 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This ensures dimensional and functional interchangeability with an existing AirTAC SC100X780 tie-rod cylinder.
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 SC100X780 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. The theoretical maximum force at 1.0 MPa is 801 kgf.
Yes, the 780 mm stroke is a non-standard, made-to-order length, as the maximum standard stroke for the 100 mm bore is 1500 mm. It does not require a custom cylinder but may have a longer lead time than standard strokes like 500 or 600 mm.
