About the Airtac SC80 Standard Cylinder SC80X757
The AirTAC SC80X757 is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion make it suitable for medium-to-heavy linear actuation tasks requiring a substantial 757 mm stroke.
This tie-rod cylinder features a PT3/8 port and an M20x1.5 rod thread. With a body length A of 182 mm, the total extended length is approximately 939 mm. The standard TPU seals provide reliable operation from -20 to +70 °C with filtered air.

Where the Airtac SC80 Standard Cylinder SC80X757 Is Used
Material Handling Pushers
The 2513 N force at 0.5 MPa and 757 mm stroke efficiently pushes boxes or pallets off conveyor lines in packaging and logistics centers.
Clamping & Fixturing
Provides robust, repeatable clamping for large workpieces in CNC machining or welding fixtures, with the adjustable cushion reducing end-of-stroke impact.
Grain Chute Diverters
Operates heavy diverter gates in agricultural processing, handling dusty conditions with the standard TPU seal and requiring no lubrication.
Is the Airtac SC80 Standard Cylinder SC80X757 the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa. If space is limited, the SC63 bore offers 1559 N. The 757 mm stroke is well within the 1500 mm maximum standard stroke for the 80 mm bore.
At this stroke length, ensure the load is guided externally if side forces are present, as the unsupported rod can experience bending moments. When replacing, match bore (80), stroke (757), PT3/8 port thread, basic mounting, and the absence of a magnet.
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 SC80X757 FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
This specific code lacks the -S suffix, so it does not have a built-in magnet. To use CMSG/DMSG/EMSG sensors, order the SC80X757-S variant. The standard model requires external limit switches for position sensing.
