About the Airtac SC80 Standard Cylinder SC80X693
The AirTAC SC80X693 is a double-acting tie-rod cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore drives a 25 mm diameter piston rod through a 693 mm stroke, making it well-suited for medium-duty linear transfer and clamping operations where a compact body length is required.
With a body length A of 182 mm and an adjustable air cushion of 28 mm at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact. The PT3/8 port and M20x1.5 rod thread provide standard pneumatic connections, while the TPU seals maintain reliable operation from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X693 Is Used
Material Transfer
Pushes or diverts medium-weight packages and components across a 693 mm travel path on conveyor lines.
Clamping & Fixturing
Applies consistent 2513 N clamping force at 0.5 MPa to hold workpieces during machining or welding.
Bin Pushing
Actuates a pusher plate to consolidate or eject bins and totes in automated storage and retrieval systems.
Is the Airtac SC80 Standard Cylinder SC80X693 the Right Cylinder?
Choose the SC80X693 when your application needs roughly 2500 N of force at standard plant air pressure. If you require more force, stepping up to the 100 mm bore (SC100 series) provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the 63 mm bore delivers 1559 N. For this 693 mm stroke, ensure the rod is not subjected to significant side loading—consider an external linear guide or a guided cylinder if the load is not perfectly axial, as the unsupported 25 mm rod can bend under lateral forces.
When replacing an existing cylinder, match five key points: 80 mm bore, 693 mm stroke, PT3/8 port thread, the specific mounting accessory (this basic model has none), and the presence of a magnet (this unit has no built-in magnet). The SC series 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 SC80X693 FAQ
At 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 reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X693 is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. The adjustable air cushion only decelerates the piston at stroke ends—it does not lock or hold the load. For position holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
