About the Airtac SC80 Standard Cylinder SC80X900N
The AirTAC SC80X900N is an 80 mm bore double-acting tie-rod cylinder with a 900 mm stroke, fitted with NBR (nitrile) seals for general-purpose pneumatic applications. 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 body length A of 182 mm and a 28 mm adjustable air cushion at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The PT1/8 port and M20x1.5 rod thread are standard for this bore. At 900 mm, the stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore, making this a standard catalog configuration.

Where the Airtac SC80 Standard Cylinder SC80X900N Is Used
Long-Reach Part Transfer
The 900 mm stroke moves parts between distant conveyor lines or workstations, with the 2513 N force at 0.5 MPa handling heavy pallets or fixtures.
Automated Gluing or Dispensing
Provides a consistent, long linear stroke for applying adhesives or sealants across large panels, where NBR seals offer good compatibility with standard lubricated air.
Bulk Bag Filling Station
Actuates a long-travel gate or clamp on a filling spout, controlling the flow of dry bulk materials into large sacks with reliable double-acting motion.
Is the Airtac SC80 Standard Cylinder SC80X900N the Right Cylinder?
The SC80X900N suits applications needing roughly 2500 N of push force at standard plant pressure. If your load requires more force, stepping up to the 100 mm bore (3927 N at 0.5 MPa) is a direct path; if you need less, the 63 mm bore provides 1559 N at 0.5 MPa. For this 900 mm stroke, ensure the rod is guided externally if the load applies any significant side force, as the long, unsupported 25 mm rod can experience bending moments.
When replacing this cylinder, match five points exactly: 80 mm bore, 900 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting configuration. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X900N 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 SC80X900N is a standard double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or drop under load. To hold a position safely, you must add an external rod lock, a pilot-operated check valve, or use a 3-position closed-center valve.
