About the Airtac SC80 Standard Cylinder SC80X1200TC
The SC80X1200TC is an AirTAC SC-series double-acting tie-rod cylinder with an 80 mm bore and a 1200 mm stroke, factory-equipped with a centre trunnion (TC) mount for pivoting applications. It generates 2513 N of push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod with an M20x1.5 male thread.
This model includes the TCM1 trunnion bracket, allowing the cylinder to swing through an arc as the rod extends and retracts—ideal for press unloaders, tilt tables, and articulated linkages. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, and the PT3/8 port threads accept standard pneumatic fittings. With a body length A of 182 mm and a total extended length of approximately 1382 mm, this genuine AirTAC cylinder is built for reliable mid-range industrial actuation.

Where the Airtac SC80 Standard Cylinder SC80X1200TC Is Used
Press Unloaders & Part Ejection
The 1200 mm stroke and centre-trunnion pivot allow the cylinder to swing a stripper plate or ejector arm clear of a press after each cycle, handling 2513 N of push force at 0.5 MPa.
Tilt Tables & Dumpers
Trunnion-mounted on both sides, the SC80X1200TC tilts bins, hoppers, or conveyor sections through a controlled arc. The 28 mm adjustable cushion absorbs the inertia of the pivoting mass at end-of-stroke.
Articulated Linkage Actuation
Used in welding fixtures and material-transfer arms where the cylinder body must pivot. The included TCM1 bracket mounts directly to the machine frame, and the M20x1.5 rod end connects to the linkage.
Is the Airtac SC80 Standard Cylinder SC80X1200TC the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2500 N and 4500 N of pneumatic force at typical shop pressures. If your load is lighter, stepping down to the SC63 (1559 N at 0.5 MPa) saves space and air consumption; for heavier work, the SC100 delivers 3927 N at the same 0.5 MPa. This 1200 mm stroke is within the 1500 mm maximum standard stroke for the 80 mm bore.
For a 1200 mm stroke, always evaluate side-loading. The 25 mm rod is robust, but an unsupported 1.2-metre extension can experience bending stress if the load is not guided. Use an external linear guide or rod-alignment coupler to protect the rod bearing and piston seals. When replacing an existing cylinder, match five points: 80 mm bore, 1200 mm stroke, PT3/8 port thread, centre-trunnion (TC) mounting with the TCM1 bracket (F-SC80TC), and the absence of a magnet—this unit does not include the -S magnet option.

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 SC80X1200TC FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa push force is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf. All figures assume a clean, filtered (40 µm) air supply within the -20 to +70 °C TPU seal temperature range.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke—mounting dimensions and body length differ. It directly replaces another AirTAC SC80 tie-rod cylinder with the same bore, stroke, PT3/8 ports, and TC centre-trunnion mount. Always verify the body length A (182 mm) and trunnion position against your machine before ordering.
