About the Airtac SC100 Standard Cylinder SC100X790
The AirTAC SC100X790 is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force when supplied with 0.5 MPa air pressure. With a 100 mm bore, 25 mm diameter piston rod, and PT1/2 pneumatic ports, it is built for demanding linear automation tasks that require a long 790 mm working stroke.
This model 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, giving a total extended length of approximately 978 mm. The standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X790 Is Used
Long-Reach Part Transfer
The 790 mm stroke moves heavy components between distant conveyor lines or workstations in automated material handling systems.
Platen Actuation for Presses
Provides the high force and long travel needed to open and close large platen-style clamping or forming fixtures in woodworking or composites.
Grain Chute Diverter
Operates a large diverter gate in agricultural processing, using its long stroke to fully open or close a chute directing bulk material flow.
Is the Airtac SC100 Standard Cylinder SC100X790 the Right Cylinder?
Select the SC100 bore when your application needs push force in the 3927 N range at standard plant pressure. If your load is lighter, stepping down to an SC80 bore (2513 N at 0.5 MPa) can reduce air consumption and physical size. For a heavier load, the SC125 (6136 N at 0.5 MPa) is the next step up.
At a 790 mm stroke, the piston rod has significant unsupported extension. To prevent rod bending or premature bearing wear, ensure the load is guided externally and aligned axially with the rod. For a direct replacement, match the 100 mm bore, 790 mm stroke, PT1/2 port thread, and basic (no bracket) mounting configuration of this SC100X790.
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 SC100X790 FAQ
At 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 reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No, the SC100X790 is a double-acting cylinder and will not hold position if air pressure is lost or the valve is centered. The piston will drift. To hold a load safely without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
