About the Airtac SC80 Standard Cylinder SC80X670S
The AirTAC SC80X670S is a double-acting tie-rod cylinder with an 80 mm bore and a 670 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for mid-to-heavy linear motion tasks.
The built-in magnet (-S suffix) allows direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel for contactless position sensing. With a body length A of 182 mm and PT3/8 ports, this cylinder is a genuine AirTAC unit designed for reliable pneumatic automation.

Where the Airtac SC80 Standard Cylinder SC80X670S Is Used
Material Transfer Gates
The 670 mm stroke and 2513 N push force reliably actuate diverter gates on wide conveyor lines, with the built-in magnet enabling end-of-stroke confirmation via barrel-mounted sensors.
Clamping & Assembly Fixtures
Delivers consistent clamping force for large workpieces. The adjustable cushion protects tooling from impact shock, while the -S magnet provides closed-loop position feedback.
Palletising & Stacking Systems
Handles the long reach required to push or lift layers onto pallets. The 25 mm rod and tie-rod construction offer rigidity for repetitive, high-cycle stacking operations.
Is the Airtac SC80 Standard Cylinder SC80X670S the Right Cylinder?
This 80 mm bore model suits applications needing around 2500 N of force. If your load is lighter, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and cost. For heavier demands, the 100 mm bore provides 3927 N at the same pressure.
At 670 mm stroke, ensure the rod is guided externally if significant side loads are present, as long unsupported strokes can cause rod bending and seal wear. For replacement, match bore, stroke, PT3/8 port thread, the built-in magnet (-S), and your mounting accessory to guarantee drop-in interchangeability with an existing AirTAC SC80 cylinder.
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 SC80X670S FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to clamp directly onto the barrel for non-contact position detection without external brackets.
