About the Airtac SC80 Standard Cylinder SC80X250S
The SC80X250S is an 80 mm bore, 250 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, factory-equipped with a built-in magnet. This model delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa, making it a robust actuator for medium-to-heavy linear tasks.
Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth end-of-stroke deceleration, while the magnet allows direct mounting of CMSG, DMSG, or EMSG sensors for reliable position feedback. The total extended body length is approximately 432 mm (182 mm body length A plus 250 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X250S Is Used
Conveyor Diverting
Pushes packages or totes off a main conveyor line onto a spur. The 2513 N force at 0.5 MPa handles heavy boxes, and the magnetic piston enables end-of-stroke sensing to confirm each divert cycle.
Clamping & Fixturing
Applies strong, consistent clamping pressure to hold metal frames or plastic parts during welding or assembly. The adjustable cushion reduces impact and vibration, protecting both the fixture and the workpiece.
Pallet Stop & Lift
Acts as a heavy-duty pallet stop or a short-stroke lift gate in material handling. The built-in magnet sensor confirms the raised or lowered position, integrating seamlessly with automated warehouse control systems.
Is the Airtac SC80 Standard Cylinder SC80X250S the Right Cylinder?
Choose the SC80 bore when your application needs between roughly 2513 N and 4523 N of pneumatic force. If your load requires less, stepping down to the SC63 bore provides 1559 N at 0.5 MPa in a more compact package. For higher force, the SC100 bore offers 3927 N at the same pressure.
At a 250 mm stroke, side-loading on the 25 mm rod is generally manageable, but always align the load axially. For a direct replacement, match these five points exactly: 80 mm bore, 250 mm stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting style.
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 SC80X250S 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.
The -S suffix equips the piston with a magnet, making it compatible with AirTAC's CMSG (reed) and DMSG/EMSG (solid-state) sensors. These sensors clamp directly onto the cylinder barrel's tie-rod slots to detect piston position without additional brackets.
