About the Airtac SC80 Standard Cylinder SC80X300N
The SC80X300N is an 80 mm bore, 300 mm stroke double-acting tie-rod cylinder fitted with NBR (nitrile) seals. It generates 2513 N of push force and 2268 N of pull force when operated at 0.5 MPa, scaling up to a substantial 4523 N at the maximum operating pressure of 0.9 MPa.
This model features a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 port connections. The adjustable pneumatic cushion, with a 28 mm cushion length, decelerates the piston smoothly at each end of the stroke. The total extended body length is approximately 482 mm (182 mm body length A + 300 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X300N Is Used
Package Diverting
Provides the 300 mm reach and 2.5 kN force at 0.5 MPa to reliably push cartons off a main conveyor line onto a sorting spur.
Clamping & Fixturing
Delivers a controlled 4523 N clamping force at 0.9 MPa for securing large workpieces during CNC machining or welding operations.
Press-Fit Assembly
The 80 mm bore generates sufficient thrust for pressing bearings or bushings into housings on a semi-automated assembly station.
Is the Airtac SC80 Standard Cylinder SC80X300N the Right Cylinder?
Choose the SC80X300N for applications needing around 2500 N of force at standard plant pressure. If your load requires less force, stepping down to a 63 mm bore reduces push force to 1559 N at 0.5 MPa; for higher force demands, the 100 mm bore provides 3927 N at the same pressure. This 300 mm stroke uses an unsupported rod; for any side-loaded application, you must guide the load externally or switch to a guided cylinder to prevent rod bending and premature seal wear.
For a direct replacement, match five key attributes: 80 mm bore, 300 mm stroke, PT port thread, basic (no bracket) mounting, and the absence of a built-in magnet. This NBR-sealed variant is suited for general industrial environments within the standard temperature range.
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 SC80X300N FAQ
At 0.5 MPa, the cylinder produces 2513 N pushing and 2268 N pulling. 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.
Yes, dimensionally it is identical. The NBR seals offer good abrasion resistance and are compatible with standard mineral oils often present in compressed air systems, making it a suitable direct replacement for an SC80X300 with TPU seals.
