About the Airtac SC80 Standard Cylinder SC80X728
The AirTAC SC80X728 is a double-acting single-rod pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. Its 728 mm stroke is within the standard range for the 80 mm bore, making it a readily available configuration for medium-duty linear actuation. The cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports.
This tie-rod cylinder features an adjustable pneumatic cushion at both ends (28 mm cushion length) to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 910 mm. Operating on filtered air at 0.15-1.0 MPa, the SC80X728 is suited for general industrial automation where reliable push-pull motion is required.

Where the Airtac SC80 Standard Cylinder SC80X728 Is Used
Material Transfer
Pushes heavy totes or bins off a conveyor line. The 2513 N force at 0.5 MPa handles substantial payloads in distribution centres.
Press-Fit Assembly
Provides controlled insertion force for bearing or bushing press-fit stations. The adjustable cushion protects parts at the end of the 728 mm stroke.
Pallet Dispensing
Acts as a long-stroke pusher to separate and dispense pallets from a stack, leveraging the full 728 mm travel for deep reach.
Is the Airtac SC80 Standard Cylinder SC80X728 the Right Cylinder?
For applications requiring slightly more force, consider stepping up to the SC100 bore, which provides 3927 N push at 0.5 MPa. If space is a constraint and lower force is acceptable, the SC63 bore offers 1559 N at the same pressure. With a 728 mm stroke, the piston rod is significantly extended; ensure the load is guided externally to prevent side-load bending of the 25 mm rod. A guided cylinder or external linear rail is recommended if the load is not perfectly axial.
To replace an existing SC80X728, match five key points: 80 mm bore, 728 mm stroke, PT3/8 port thread, basic mounting (no integral brackets), and no built-in magnet. The SC is a tie-rod cylinder 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 SC80X728 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 SC80X728 is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centred. The adjustable air cushion only decelerates the piston at stroke ends; it does not lock or hold position. For load holding, add a pilot-operated check valve or an external rod brake.
