About the Airtac SC80 Standard Cylinder SC80X743
The AirTAC SC80X743 is a double-acting single-rod pneumatic cylinder with an 80 mm bore and a non-standard 743 mm stroke, built for applications needing a long linear reach with substantial force. At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force, rising to a robust 4523 N at the maximum operating pressure of 0.9 MPa.
This tie-rod cylinder features a 25 mm diameter piston rod with an M20x1.5 thread and PT3/8 ports. The extended body length is approximately 925 mm (body length A of 182 mm plus the 743 mm stroke). It includes an adjustable pneumatic cushion over a 28 mm length to decelerate the piston smoothly at end-of-travel, reducing impact and noise.

Where the Airtac SC80 Standard Cylinder SC80X743 Is Used
Long-Reach Material Pusher
The 743 mm stroke is ideal for a long-stroke pusher on a wide conveyor, diverting heavy packages or pallets off the main line. Its 2513 N force at 0.5 MPa handles substantial product weights reliably.
Heavy-Duty Clamp Actuation
Use this cylinder to actuate a heavy-duty welding or assembly clamp requiring a deep opening. The adjustable cushioning at both ends ensures a smooth, low-impact stop for the large fixture, protecting the tooling.
Grain Chute Diverter Gate
Operates a large diverter gate on a grain or aggregate chute. The high force output and long stroke provide the necessary travel and power to shift the heavy, material-laden gate securely between positions.
Is the Airtac SC80 Standard Cylinder SC80X743 the Right Cylinder?
Select the SC80 bore when your application requires a push force between 2513 N and 4523 N. If your load requires less force, stepping down to an SC63 bore provides 1559 N at 0.5 MPa and may reduce air consumption. For higher force needs, the SC100 bore delivers 3927 N at the same pressure. This 743 mm stroke is non-standard and requires a made-to-order configuration.
For any stroke over 300 mm, especially with this 25 mm rod, carefully evaluate side loads. An unsupported long stroke rod is susceptible to bending under lateral forces. To ensure reliable operation and prevent seal damage, use an external linear guide or a guided cylinder to absorb side loads, keeping the rod in pure tension and compression. When replacing an existing unit, match the 80 mm bore, 743 mm stroke, PT3/8 port thread, basic mounting configuration, and confirm if a magnet is required for sensors.
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 SC80X743 FAQ
At the standard operating pressure of 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 maximum standard stroke for an 80 mm bore SC cylinder is 1500 mm, but a 743 mm stroke is not a standard increment. This is a non-standard, made-to-order stroke length. You must confirm the exact part number and lead time with your supplier.
