About the Airtac SC80 Standard Cylinder SC80X50N
The AirTAC SC80X50N is an 80 mm bore, 50 mm stroke double-acting tie-rod cylinder fitted with NBR (nitrile) seals. It produces a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
With a compact body length A of 182 mm and a 28 mm adjustable air cushion, this cylinder is built for short, precise linear movements. The NBR seal material offers reliable performance for general industrial applications, and the standard PT1/4 port thread ensures straightforward pneumatic connection.

Where the Airtac SC80 Standard Cylinder SC80X50N Is Used
Part Ejection
Delivers a rapid 2513 N push at 0.5 MPa to eject parts from a conveyor or stamping die, with a short 50 mm stroke for fast cycle times.
Clamping Fixtures
Provides a strong, consistent clamping force for workholding in machining centers, using the 28 mm air cushion to reduce impact at the end of stroke.
Valve Actuation
Powers the opening and closing of small to medium-sized ball or butterfly valves, where a short, high-force linear stroke is required.
Is the Airtac SC80 Standard Cylinder SC80X50N the Right Cylinder?
For applications requiring less force, consider stepping down to the 63 mm bore SC63 series, which provides 1559 N of push force at 0.5 MPa. If you need higher force, the 100 mm bore SC100 series offers 3927 N at the same pressure. The 50 mm stroke is a standard length for this bore.
When replacing an existing cylinder, ensure a 5-point match: 80 mm bore, 50 mm stroke, PT3/8 port thread, basic mounting (no bracket), and no magnet. This model uses NBR seals, so confirm material compatibility if replacing a TPU or Viton sealed unit.
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 SC80X50N FAQ
At 0.5 MPa, 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 AirTAC SC series is a tie-rod cylinder and is shorter than a standard ISO 15552 cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching bore, stroke, port thread (PT), and NBR seals.
