About the Airtac SC80 Standard Cylinder SC80X755STC
The SC80X755STC 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. With an 80 mm bore, 25 mm piston rod, and a 755 mm stroke, this model is built for linear applications needing substantial force over a long travel distance.
This configuration includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC80TC) to allow the cylinder to pivot during operation. The adjustable air cushion at each end is 28 mm long, effectively decelerating the piston to reduce end-of-stroke impact.

Where the Airtac SC80 Standard Cylinder SC80X755STC Is Used
Material Handling Pusher
The 2513 N push force at 0.5 MPa easily moves heavy totes or pallets on a conveyor line, with the 755 mm stroke providing the long reach needed for cross-push transfer stations.
Welding Fixture Clamping
Delivers consistent clamping pressure for large weldments. The centre trunnion mount allows the cylinder body to pivot, accommodating fixture movement, while the magnetic sensors confirm jaw position.
Grain Chute Diverter
Actuates a large diverter gate in agricultural processing. The 755 mm stroke offers full gate travel, and the trunnion mount handles the arcing motion of the linkage without side-loading the rod.
Is the Airtac SC80 Standard Cylinder SC80X755STC the Right Cylinder?
For applications requiring slightly less force, stepping down to a 63 mm bore provides 1559 N at 0.5 MPa. For higher force demands, the 100 mm bore offers 3927 N at the same pressure. At a 755 mm stroke, ensure the rod is protected from side loading; an external guide or a guided cylinder is recommended to prevent rod bearing damage and bending over this extended unsupported length.
When replacing this cylinder, match five key points: 80 mm bore, 755 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet for sensors. The SC series is a tie-rod design, shorter than ISO 15552 cylinders, and is not dimensionally interchangeable with them.
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 SC80X755STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N. At 0.7 MPa it delivers 3518 N, and at the maximum operating pressure of 0.9 MPa, the force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No, the SC80X755STC is a double-acting cylinder and will not hold its position or load if air pressure is lost or the directional valve is centered. The piston will drift or drop. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod brake.
