About the Airtac SC80 Standard Cylinder SC80X400
The SC80X400 is a double-acting pneumatic cylinder delivering a substantial 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion make it a robust choice for medium-duty automation tasks requiring a 400 mm linear stroke.
This tie-rod cylinder has a compact body length of 182 mm, resulting in a total extended length of approximately 582 mm. With PT3/8 ports and a standard TPU seal for a -20 to +70 °C operating range, it is a genuine AirTAC workhorse built for reliable, high-cycle performance in industrial environments.

Where the Airtac SC80 Standard Cylinder SC80X400 Is Used
Package Sorting Gates
The 400 mm stroke and 2513 N force at 0.5 MPa effectively divert medium-weight packages on conveyor lines, providing a decisive push with adjustable cushioning for smooth operation.
Material Clamping
Ideal for holding workpieces in CNC or welding fixtures, the SC80X400 applies over 2.5 kN of stable clamping force, with the tie-rod design ensuring rigidity under repetitive cycles.
Press-Fit Assembly
With a peak theoretical force of 4523 N at 0.9 MPa, this cylinder can be used in light press-fit or forming stations, reliably inserting bearings or bushings with controlled pneumatic power.
Is the Airtac SC80 Standard Cylinder SC80X400 the Right Cylinder?
For applications needing slightly less force, consider stepping down to the 63 mm bore, which provides 1559 N of push force at 0.5 MPa. If your load requires more power, the 100 mm bore model offers 3927 N at the same pressure. This 400 mm stroke is a standard length, but always check for potential rod bending under side loads.
For strokes of 300 mm or more, avoid direct side loading on the rod. An external guide or a guided cylinder assembly is strongly recommended to prevent rod bearing damage and ensure long service life. When replacing this cylinder, match the 80 mm bore, 400 mm stroke, PT3/8 port thread, basic mounting configuration, and the absence of a magnet to guarantee a correct fit.
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 SC80X400 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 force at 1.0 MPa is 513 kgf.
No, the SC80X400 is a standard double-acting cylinder and cannot hold a load if air pressure is lost or the valve is centered. The adjustable air cushion only decelerates the piston at the stroke ends. For position holding, you must add an external rod lock or a pilot-operated check valve.
