About the Airtac SC80 Standard Cylinder SC80X700LB
The SC80X700LB is an 80 mm bore, 700 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial 2513 N of push force when supplied with 0.5 MPa air pressure, rising to 4523 N at the maximum operating pressure of 0.9 MPa, making it a strong candidate for medium-to-heavy linear actuation tasks.
This model comes factory-assembled with the LB foot mounting (accessory code F-SC80LB), providing a stable axial base for surface mounting. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end ensure smooth deceleration, while the PT1/4 port thread and M20x1.5 rod thread offer straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X700LB Is Used
Belt Conveyor Diverters
The 700 mm stroke and 2500+ N push force reliably actuate heavy-duty diverter gates on wide conveyor lines, sorting packages or materials at high speed.
Industrial Press Feeders
Provides the long, consistent stroke needed to feed sheet metal or composite blanks into stamping presses, with the foot mount ensuring rigid alignment.
Log Splitter Actuation
Delivers the high force and extended reach required for small-to-medium hydraulic-free log splitters, using the LB mount for a secure, stationary setup.
Is the Airtac SC80 Standard Cylinder SC80X700LB the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC63 delivers 1559 N at the same pressure. With a 700 mm stroke, ensure the rod is protected from side loads; an external linear guide is recommended to prevent rod bending and premature bearing wear.
To guarantee a correct replacement, match five key points: 80 mm bore, 700 mm stroke, PT port thread, LB foot mounting, and the absence of a built-in magnet. This 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 SC80X700LB 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80 is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
