About the Airtac SC80 Standard Cylinder SC80X1200STC
The SC80X1200STC is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod. This 80 mm bore model features a built-in magnet and a centre trunnion (TC) mount, making it ideal for pivoting applications with a 1200 mm stroke.
With a 28 mm adjustable air cushion at each end, the cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 1382 mm. The PT1/8 port and M20x1.5 rod thread match standard AirTAC SC80 pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X1200STC Is Used
Long-Reach Material Transfer
The 1200 mm stroke and 2513 N push force shift heavy pallets or panels between conveyor lanes, with the trunnion mount allowing the cylinder to pivot as it extends.
Pivoting Clamp & Fixture Actuation
Centre trunnion mounting lets the SC80X1200STC swing into position, applying 4523 N of clamping force at 0.9 MPa for welding or assembly fixtures.
Grain Chute or Diverter Gate Control
The magnet-equipped barrel works with CMSG/DMSG sensors to confirm open/closed position of a large diverter gate, while the trunnion absorbs the arc motion.
Is the Airtac SC80 Standard Cylinder SC80X1200STC the Right Cylinder?
For higher force, step up to the SC100 bore (3927 N at 0.5 MPa); for a lighter, faster actuator, the SC63 offers 1559 N. At a 1200 mm stroke, side-load management is critical—always guide the rod externally or use a guided cylinder to prevent bending and premature bearing wear. This model is a direct replacement only for another AirTAC SC80 tie-rod cylinder matching the 1200 mm stroke, PT ports, centre trunnion mount, and built-in magnet (-S).
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 SC80X1200STC FAQ
At the standard 0.7 MPa operating pressure, push force is 3518 N and pull force is 3175 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It directly replaces another AirTAC SC80 of the same stroke with a TC trunnion mount, PT ports, and a magnet.
