About the Airtac SC80 Standard Cylinder SC80X400N
The SC80X400N is an 80 mm bore, 400 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, fitted with NBR (nitrile) seals. At the standard operating pressure of 0.5 MPa, this cylinder delivers a push force of 2513 N and a pull force of 2268 N, driven by a 25 mm diameter piston rod.
With a total extended body length of 582 mm (182 mm body plus 400 mm stroke), this model is built for medium-to-heavy linear actuation tasks. The adjustable pneumatic cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. This cylinder uses a PT1/8 port and an M20x1.5 rod thread for standard pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X400N Is Used
Package Sorting Gates
Provides the 2500 N push needed to divert medium-weight parcels on high-speed conveyor lines, with NBR seals offering good wear resistance in dry, lubricated air systems.
Clamping & Assembly Fixtures
Delivers controlled clamping force for woodworking or metal fab jigs. The 400 mm stroke accommodates a wide range of part sizes in automated assembly cells.
Agricultural Equipment Actuation
Operates chutes, gates, or diverters on seed and grain handling machinery. The nitrile seals are compatible with the oily air often found in farm workshop environments.
Is the Airtac SC80 Standard Cylinder SC80X400N the Right Cylinder?
The SC80X400N suits applications needing around 2500 N of force at standard shop air. If your load requires less force, stepping down to the 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For higher force demands, the 100 mm bore provides 3927 N at the same pressure.
At a 400 mm stroke, ensure the rod is protected from significant side loads; an unsupported 25 mm rod can bend under lateral force. For such cases, add an external linear guide or consider a guided cylinder. When replacing this unit, match five key points: 80 mm bore, 400 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting configuration.
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 SC80X400N FAQ
At 0.5 MPa (5 bar), the cylinder produces 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The NBR (nitrile) seals on this model are rated for the standard SC temperature range of -20 to +70 °C. For applications up to +150 °C, you would need the 'H' suffix variant (Viton seals), such as the SC80X400H.
