About the Airtac SC80 Standard Cylinder SC80X777
The AirTAC SC80X777 is an 80 mm bore, double-acting pneumatic cylinder with a non-standard 777 mm stroke. At 0.5 MPa, it generates 2513 N of push force and 2268 N of pull force, scaling up to a robust 4523 N at the maximum operating pressure of 0.9 MPa. The 25 mm diameter piston rod and 28 mm adjustable air cushion are designed to manage high-cycle deceleration.
This is a genuine AirTAC tie-rod cylinder built with a TPU seal for a standard operating temperature range of -20 to +70 °C. The body length A is 182 mm, making the total extended length approximately 959 mm. With a PT3/8 port, it requires careful alignment for this long, non-standard stroke to prevent side-loading the rod bearing.

Where the Airtac SC80 Standard Cylinder SC80X777 Is Used
Long-Stroke Material Pusher
Ideal for pushing heavy pallets or goods off a conveyor line where a long, controlled 777 mm travel is needed to clear the main transport path.
Vertical Door Actuation
Provides the 2513 N of force at 0.5 MPa to reliably lift or lower a large industrial door or hopper gate, with the adjustable cushion softening the end-of-stroke impact.
Custom Machinery Feed System
Used in a bespoke machine tool to advance a heavy carriage across a 777 mm distance, where the tie-rod design allows for straightforward field maintenance.
Is the Airtac SC80 Standard Cylinder SC80X777 the Right Cylinder?
For a step up in force, the 100 mm bore model offers 3927 N at 0.5 MPa. If space is a constraint, the 63 mm bore provides 1559 N. For this 777 mm stroke, an external guide or guided cylinder is strongly recommended to protect the rod bearing from bending moments caused by side loads. A long, unsupported 25 mm rod is susceptible to deflection.
To ensure a correct replacement, match five key specifications: the 80 mm bore, the 777 mm stroke, the PT3/8 port thread, the basic (no bracket) mounting style, and the absence of a built-in magnet. This model 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 SC80X777 FAQ
The theoretical push force is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and reaches a maximum of 4523 N at the 0.9 MPa operating pressure limit. The pull force is slightly lower due to the 25 mm rod area.
No, the maximum standard stroke for an 80 mm bore SC cylinder is 1500 mm, but 777 mm is not a standard catalog stroke. It is a made-to-order, non-standard stroke length. You must confirm the lead time with your supplier.
