About the Airtac SC80 Standard Cylinder SC80X580STC
The SC80X580STC is a double-acting pneumatic cylinder delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, rising to a robust 4523 N push force at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 580 mm stroke, this model features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC centre trunnion mount, which ships with the TCM1 bracket (F-SC80TC). The trunnion allows the cylinder to pivot, making it ideal for swinging or articulating loads. The total extended body length is approximately 762 mm (182 mm body length A + 580 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X580STC Is Used
Part Diverter on Conveyors
The 580 mm stroke and pivoting trunnion mount allow this cylinder to swing a diverter gate across a wide conveyor line, sorting packages or products with controlled, cushioned motion.
Clamp-and-Rotate Fixtures
With the TC centre trunnion, the SC80X580STC can pivot a welding or assembly fixture into position. The 2513 N force at 0.5 MPa securely clamps large workpieces before rotation.
Agricultural Chute Actuation
Operates a long-throw discharge chute on a grain or feed handling system. The magnetic piston allows end-of-stroke confirmation via sensors, ensuring the chute fully opens or closes.
Is the Airtac SC80 Standard Cylinder SC80X580STC the Right Cylinder?
For applications requiring slightly less force, stepping down to a 63 mm bore (SC63 series) provides 1559 N of push force at 0.5 MPa. If higher force is needed, the 100 mm bore (SC100 series) delivers 3927 N at the same pressure. Always match replacement cylinders on all five critical points: 80 mm bore, 580 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S).
At a 580 mm stroke, the 25 mm rod is extended significantly. To prevent rod bending or bearing wear, ensure the load is guided externally and purely axial. Any side load on an unsupported rod of this length can cause premature seal failure; use an external guide rail or rod-alignment coupler.
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 SC80X580STC FAQ
At the standard operating pressure of 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 AirTAC SC series is a tie-rod cylinder and its body length (182 mm for the 80 bore) is shorter than an equivalent ISO 15552 profile cylinder. It is a direct dimensional match only for another AirTAC SC80 tie-rod cylinder with the same stroke, PT ports, TC mount, and magnet.
