About the Airtac SC80 Standard Cylinder SC80X1200S
The SC80X1200S is an AirTAC SC series double-acting tie-rod cylinder with an 80 mm bore and a 1200 mm stroke, equipped with a built-in magnet. Operating at 0.5 MPa, it provides a push force of 2513 N and a pull force of 2268 N, making it a robust linear actuator for demanding mid-range automation tasks. The 25 mm diameter piston rod and 28 mm adjustable air cushion ensure smooth deceleration even under substantial end-of-stroke loads.
This model features a PT3/8 port and an M20x1.5 rod thread, with a body length A of 182 mm. The integrated magnet allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise, non-contact position sensing. As a genuine AirTAC component, it is built for reliable, long-life performance in filtered air systems.

Where the Airtac SC80 Standard Cylinder SC80X1200S Is Used
Long-Reach Material Transfer
Pushes or pulls heavy bins and pallets across wide conveyor gaps, using its 1200 mm stroke to bridge transfer zones where shorter cylinders cannot reach.
Sawmill Log Flipping
Provides the sustained 2513 N force needed to turn and position large timber cants on a carriage, with the magnet sensors confirming full extension and retraction in dirty environments.
Large Panel Clamping
Applies consistent, even pressure across wide assembly fixtures for gluing or welding large panels, with the adjustable cushion preventing impact damage to the fixture.
Is the Airtac SC80 Standard Cylinder SC80X1200S the Right Cylinder?
Select the SC80 bore when the 50 mm bore's 982 N push force at 0.5 MPa is insufficient for the application's load. If the cycle requires higher speed or force, stepping up to the 100 mm bore provides a substantial jump to 3927 N at the same pressure. For this 1200 mm stroke, careful alignment is critical; any side load on the fully extended 25 mm rod can cause bending and premature bearing wear. Always use an external guide or rod support for non-axial loads.
To replace this cylinder, match five key specifications: the 80 mm bore, the 1200 mm stroke, the PT3/8 port thread, the basic mounting configuration, and the built-in magnet (-S suffix) for sensor compatibility. This ensures the replacement will fit the existing plumbing, mounting points, and control system without modification.
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 SC80X1200S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder generates a push force of 2513 N and a pull force of 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. A 1200 mm stroke with a 25 mm rod is highly susceptible to bending under side loads. The cylinder must be used for purely axial pushing or pulling. If a side load is unavoidable, an external linear guide rail system must be installed to absorb the lateral forces and protect the rod bearings and seals.
