About the Airtac SC80 Standard Cylinder SC80X500STC
The AirTAC SC80X500STC is an 80 mm bore double-acting tie-rod cylinder delivering 500 mm of stroke, factory-equipped with a built-in magnet and a centre trunnion mount. At 0.5 MPa air pressure it generates 2513 N pushing force and 2268 N on the pull stroke, placing it in a robust mid-range force class for general automation.
The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide smooth deceleration for moving moderate loads. Its PT3/8 port threads and M20x1.5 rod thread are standard for this bore, and the body length A is 182 mm, making the total extended length approximately 682 mm. This model is a genuine AirTAC SC cylinder, built for reliable industrial service.

Where the Airtac SC80 Standard Cylinder SC80X500STC Is Used
Conveyor Sorting Gate
The 500 mm stroke and centre trunnion pivot allow the cylinder to swing a diverter arm across a wide conveyor, sorting packages by weight or destination with the 2513 N push force at 0.5 MPa.
Material Roll Stand Tensioner
Apply consistent tension to a web of paper or film. The adjustable cushioning protects the roll stand mechanics, and the built-in magnet enables end-of-stroke sensing for precise dancer arm position feedback.
Welding Fixture Clamp
Operate a large pivoting clamp arm in a weld cell. The centre trunnion mount allows the cylinder body to swing, while the 25 mm rod and 2268 N pull force securely lock the fixture during the weld cycle.
Is the Airtac SC80 Standard Cylinder SC80X500STC the Right Cylinder?
Choose the SC80 bore when 50 mm bore force (982 N push at 0.5 MPa) is insufficient but the full capacity of a 100 mm bore (3927 N) is not required. The 500 mm stroke is well within the 1500 mm maximum standard stroke for this bore. For strokes of this length, ensure the rod is not subjected to significant side loading; if the application involves off-axis forces, add an external linear guide or switch to a guided cylinder to protect the rod bearing and seals.
To replace an existing cylinder, match these five points exactly: 80 mm bore, 500 mm stroke, PT port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X500STC FAQ
At the standard 0.5 MPa operating pressure, the pushing force is 2513 N and the pulling 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 is shorter than an equivalent ISO 15552 cylinder. It is not dimensionally interchangeable. It can only replace another AirTAC SC tie-rod cylinder with the same bore, stroke, mounting, and port thread.
