About the Airtac SC80 Standard Cylinder SC80X1200
The SC80X1200 is an 80 mm bore double-acting pneumatic cylinder delivering a 1200 mm stroke, ideal for long linear movements in material handling and process automation. At 0.5 MPa it provides 2513 N of push force, rising to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This tie-rod cylinder features an adjustable pneumatic cushion (28 mm length) at both ends to decelerate the piston smoothly, protecting end caps and reducing noise. The body length A is 182 mm, giving a total extended length of approximately 1382 mm. Standard PT3/8 ports and TPU seals rated for -20 to +70 °C are fitted, making this a robust, genuine AirTAC actuator for demanding long-stroke tasks.

Where the Airtac SC80 Standard Cylinder SC80X1200 Is Used
Long-Reach Part Transfer
Moves components or pallets across a 1200 mm span between conveyor lines or workstations, using the high push force to shift heavy loads reliably.
Vertical Lift Gate Actuation
Operates tall vertical lift gates or hopper doors in agricultural and bulk-material handling, where the long stroke provides full clearance without complex linkages.
Timber or Panel Positioning
Positions large sheet materials like plywood or MDF in sawing or routing centres, leveraging the 2513 N force at standard line pressure for smooth, controlled indexing.
Is the Airtac SC80 Standard Cylinder SC80X1200 the Right Cylinder?
For a 1200 mm stroke, the SC80 bore provides a strong force platform, but always assess side-loading risks on the fully extended 25 mm rod. At this length, an external guide or self-guided tooling is strongly recommended to prevent rod bending and premature bearing wear. If the application requires less force, stepping down to the SC63 bore offers 1559 N at 0.5 MPa; for higher force, the SC100 bore provides 3927 N at 0.5 MPa.
When replacing an existing cylinder, match five key points to ensure drop-in compatibility: 80 mm bore, 1200 mm stroke, PT3/8 port thread, basic mounting (no factory-fitted bracket), and no built-in magnet. This model is a standard-stroke SC cylinder, as the 1200 mm stroke is within the 1500 mm maximum for bore 80.
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 SC80X1200 FAQ
At 0.7 MPa operating pressure, the SC80 bore generates a theoretical push force of 3518 N. The pull force on the retract stroke is 2268 N at 0.5 MPa, due to the area reduction from the 25 mm rod.
It is not recommended. A 25 mm rod extended to 1200 mm is susceptible to bending under side loads. Always use an external guide rail or rod-supported tooling to absorb transverse forces and protect the rod bearing and piston seals.
