About the Airtac SC80 Standard Cylinder SC80X680
The AirTAC SC80X680 is an 80 mm bore double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa (4523 N at the maximum operating pressure of 0.9 MPa). With a 680 mm stroke, this model provides a substantial working reach, making it suitable for medium-duty material transfer and pressing operations where a compact body length is required.
This cylinder features a 25 mm diameter piston rod with an M20x1.5 thread and PT3/8 ports. The adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact noise and vibration. The total extended body length is approximately 862 mm (body length A of 182 mm plus the 680 mm stroke).

Where the Airtac SC80 Standard Cylinder SC80X680 Is Used
Part Transfer & Indexing
The 680 mm stroke moves components between conveyor lines or indexing stations, with the 2513 N force at 0.5 MPa reliably pushing pallets or fixtures.
Light Assembly Pressing
Ideal for pressing bearings, bushings, or clips into housings where a controlled 4523 N maximum force at 0.9 MPa is needed without the complexity of a hydraulic system.
Automated Gate or Diverter
Operates a material diverter gate or chute flap on a packaging or processing line, using the adjustable cushion to ensure quiet, low-impact end-of-stroke positioning.
Is the Airtac SC80 Standard Cylinder SC80X680 the Right Cylinder?
For applications requiring more force, consider stepping up to the 100 mm bore SC100 series, which provides 3927 N of push force at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore SC63 series offers 1559 N at the same pressure. At a 680 mm stroke, ensure the rod is adequately supported against side loads; an external linear guide or rod-alignment coupler is recommended to prevent rod bearing wear and bending, as the 25 mm rod is not designed to carry heavy transverse loads unsupported.
When replacing an existing cylinder, verify five key points for a direct match: the 80 mm bore, 680 mm stroke, PT3/8 port thread, the specific mounting accessory (this is a basic body, so no pre-attached brackets), and the absence of a built-in magnet. This ensures the SC80X680 fits the existing mounting space and pneumatic circuit 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 SC80X680 FAQ
At the standard 0.5 MPa operating pressure, 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 with a shorter body length than a standard ISO 15552 profile cylinder, so the mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same 680 mm stroke, PT3/8 ports, and basic mounting configuration.
