About the Airtac SC80 Standard Cylinder SC80X250LB
The SC80X250LB is an 80 mm bore, 250 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports.
This model comes factory-assembled with LB axial foot mounts (part code F-SC80LB) for secure surface installation. The adjustable air cushion at each end decelerates the piston over 28 mm to reduce end-of-stroke impact. Its compact tie-rod body has a base length of 182 mm, extending to 432 mm total length in this configuration.

Where the Airtac SC80 Standard Cylinder SC80X250LB Is Used
Belt Tensioning & Roller Actuation
Applies the consistent 2.5 kN force needed to tension heavy conveyor belts or actuate guide rollers in aggregate and mining material handling lines.
Clamping & Assembly Fixtures
Delivers powerful, controlled clamping for woodworking, welding, or assembly jigs. The LB foot mount allows rigid bolting to a machine table for repeatable part positioning.
Bin Gate & Diverter Control
Operates sliding gates or flow diverters on silos and hoppers. The 250 mm stroke provides the linear travel needed to fully open or close material flow paths.
Is the Airtac SC80 Standard Cylinder SC80X250LB the Right Cylinder?
For higher force, the 100 mm bore SC100 series provides 3927 N at 0.5 MPa. If space is tight, stepping down to the 63 mm bore (1559 N at 0.5 MPa) may suffice. At 250 mm stroke, the 25 mm rod is robust for axial loads, but any significant side force requires an external linear guide to prevent rod bearing wear and seal failure.
When replacing an existing unit, match five points: 80 mm bore, 250 mm stroke, PT3/8 port thread, LB foot mounting (F-SC80LB), and the absence of a magnet sensor option. This cylinder is a direct dimensional match only for another AirTAC SC80 tie-rod cylinder.
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 SC80X250LB FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 3165 N (accounting for the 25 mm rod area). Maximum force at 0.9 MPa is 4523 N push.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 types. Use it to replace another AirTAC SC80 tie-rod cylinder with matching port, mounting, and stroke specifications.
