About the Airtac SC100 Standard Cylinder SC100X78
The AirTAC SC100X78 is a 100 mm bore double-acting tie-rod cylinder with a 78 mm standard stroke, delivering a substantial 3927 N push force at 0.5 MPa (7068 N at the maximum operating pressure of 0.9 MPa). Its 25 mm diameter piston rod and PT1/2 porting provide a robust, high-force package for industrial automation tasks that require a short, powerful linear movement.
With a body length A of 188 mm, the total extended length is approximately 266 mm. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at stroke end, reducing impact and noise. This model uses standard TPU seals for a -20 to +70 °C operating range and PT threads.

Where the Airtac SC100 Standard Cylinder SC100X78 Is Used
Heavy-Duty Clamping
Generates up to 7068 N of clamping force at 0.9 MPa for securely holding large workpieces during machining or welding operations.
Pallet Stop & Lift
Provides a powerful, short-stroke lift or stop action on conveyor lines, reliably handling heavy pallets or totes with its 3927 N push at standard shop air.
Forming Press Actuator
Delivers the high initial force needed for light forming, pressing, or riveting tasks in a compact 266 mm extended length, fitting into tight machine frames.
Is the Airtac SC100 Standard Cylinder SC100X78 the Right Cylinder?
For applications needing slightly less force, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa. If your stroke requires a longer unsupported extension, consider an external guide or a guided cylinder to protect the 25 mm rod from side-load bending. To ensure a correct replacement, match five points: 100 mm bore, 78 mm stroke, PT1/2 port thread, basic (no) 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 SC100X78 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, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X78 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. For load holding without live pressure, you must add an external rod lock, brake, or a pilot-operated check valve.
