About the Airtac SC80 Standard Cylinder SC80X773
The AirTAC SC80X773 is a double-acting pneumatic cylinder engineered for applications requiring an extended reach with a substantial force output. With an 80 mm bore and a non-standard 773 mm stroke, it generates a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model features a 28 mm adjustable air cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The total extended body length is approximately 955 mm (body length A of 182 mm plus the 773 mm stroke). As a tie-rod cylinder, it is shorter than an equivalent ISO 15552 profile, making it a compact solution for space-constrained linear motion tasks.

Where the Airtac SC80 Standard Cylinder SC80X773 Is Used
Long-Reach Part Transfer
Moves components across a wide gap between conveyor lines, utilizing the full 773 mm stroke to push or lift parts where a shorter cylinder would require a complex linkage.
Vertical Door Actuation
Operates a tall industrial door or vertical lift gate. The 2513 N push force at standard line pressure provides ample power to raise a heavy panel smoothly against gravity.
Baler or Compactor Ejection
Ejects compacted material bales from a chamber. The high force at 0.9 MPa (4523 N) combined with the extended stroke ensures complete, reliable ejection of the finished bale onto a take-away conveyor.
Is the Airtac SC80 Standard Cylinder SC80X773 the Right Cylinder?
Select the SC80X773 when the 63 mm bore's 1559 N push force at 0.5 MPa is insufficient for the load, but a jump to the 100 mm bore's 3927 N is excessive. For this 773 mm stroke, carefully manage side loads; a long, unsupported 25 mm rod is susceptible to bending under lateral forces. Always use an external linear guide or ensure the load is purely axial to prevent premature rod bearing and seal wear.
To ensure a correct replacement, match five key specifications: an 80 mm bore, the exact 773 mm stroke, PT1/4 port thread, the required mounting accessory, and the presence or absence of a magnet. This basic configuration uses the default TPU seals and PT threads without a mounting bracket.
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 SC80X773 FAQ
At 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 reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No, the SC80X773 is not designed for unguided side loads. The 25 mm rod, when fully extended to 773 mm, is vulnerable to bending. You must mount the load on an external linear guide rail system to absorb all lateral and moment forces, protecting the rod bearing and seals.
