About the Airtac SC80 Standard Cylinder SC80X1340
The AirTAC SC80X1340 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 80 mm bore and 1340 mm stroke suit long-travel linear actuation tasks where consistent pneumatic force is required within the standard stroke limit.
This model features a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports. The body length A is 182 mm, giving an extended length of approximately 1522 mm. An adjustable air cushion (28 mm length) decelerates the piston at stroke ends to reduce impact, though external guidance is essential at this stroke length to protect the rod from bending under side loads.

Where the Airtac SC80 Standard Cylinder SC80X1340 Is Used
Long-Reach Material Transfer
Pushes or pulls product carriers across wide conveyor gaps or transfer stations, using the 1340 mm stroke to bridge extended distances without intermediate stops.
Panel Indexing & Positioning
Moves large panels or sheets into precise stations in woodworking or metal fabrication lines, where the 2513 N force at 0.5 MPa handles substantial workpiece masses.
Pallet Dispensing Systems
Extends a stop gate or pusher plate deep into a pallet magazine, releasing or separating pallets one at a time with controlled, repeatable motion.
Is the Airtac SC80 Standard Cylinder SC80X1340 the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N (push at 0.5 MPa) and 4523 N (push at 0.9 MPa). If you require higher force, step up to the SC100 which provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 delivers 1559 N at the same pressure. For this 1340 mm stroke, side-load management is critical—install an external linear guide or rod support to prevent bearing wear and rod deflection, as long unsupported strokes concentrate bending moments on the piston rod.
When replacing an existing cylinder, match five key points: 80 mm bore, 1340 mm stroke, PT3/8 port thread, basic mounting (no bracket), and no magnet. This SC 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 SC80X1340 FAQ
At 0.5 MPa air pressure, the cylinder produces 2513 N extending (push) and 2268 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf. Actual force depends on your system's regulated pressure.
A 1340 mm stroke with a 25 mm rod creates a long lever arm that is vulnerable to side loads. Always mount the load on an external linear guide or rail system so the cylinder only provides push/pull force, not load support. For applications with unavoidable side forces, consider a guided cylinder or add an external rod support.
