About the Airtac SC80 Standard Cylinder SC80X178
The SC80X178 is an 80 mm bore, 178 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod family. It produces a push force of 2513 N at 0.5 MPa and up to 4523 N at the 0.9 MPa maximum operating pressure, driven by a 25 mm diameter piston rod.
With a compact body length A of 182 mm, the total extended length reaches approximately 360 mm. The cylinder includes PT3/8 ports, an M20x1.5 rod thread, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly. This genuine AirTAC unit is built for reliable factory automation tasks.

Where the Airtac SC80 Standard Cylinder SC80X178 Is Used
Package Sorting Gates
Actuates diverter gates on conveyor lines. The 2513 N push force at 0.5 MPa reliably shifts parcels and cartons, while the 28 mm cushion absorbs impact for quiet, long-life operation.
Clamping & Fixturing
Provides strong, consistent clamping pressure for machining or welding fixtures. The adjustable cushion allows fine-tuning the clamp engagement speed to avoid part damage.
Pallet Lift Assist
Used in lift-and-lower mechanisms for pallet dispensers. The 178 mm stroke offers a useful vertical travel, and the double-acting control ensures positive movement in both directions.
Is the Airtac SC80 Standard Cylinder SC80X178 the Right Cylinder?
Select the SC80X178 when your application needs roughly 2500 N of push force at standard shop air. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and footprint. For heavier work, the 100 mm bore provides 3927 N at the same pressure.
For this 178 mm stroke, the 25 mm rod is robust for most axial loads. If you are pushing an offset or unguided mass, always use an external guide or linear bearing to protect the rod bearing from bending moments. When replacing an existing cylinder, match five key points: 80 mm bore, 178 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a 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 SC80 Standard Cylinder SC80X178 FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC 80 mm bore cylinder with the same stroke, port thread, and mounting configuration.
