About the Airtac SC80 Standard Cylinder SC80X628
The SC80X628 is an 80 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, offering a 628 mm standard stroke. At 0.5 MPa it produces 2513 N of push force, scaling to 4523 N at the 0.9 MPa maximum operating pressure, driven by a 25 mm diameter piston rod.
This model features adjustable air cushioning with a 28 mm cushion length to decelerate end-of-stroke impact. The body length A is 182 mm, giving a total extended length of approximately 810 mm. Ports are PT3/8 and the rod thread is M20x1.5. It ships with default TPU seals for a -20 to +70 °C operating range.

Where the Airtac SC80 Standard Cylinder SC80X628 Is Used
Pallet Stop & Transfer
The 2513 N push force at 0.5 MPa reliably raises and positions pallet stops on gravity or powered roller conveyors, with the 628 mm stroke handling wide transfer sections.
Clamping & Fixturing
Applies controlled clamping pressure for large weldments or assembly fixtures. The adjustable cushion protects tooling from impact at the end of the 628 mm stroke.
Baler & Compactor Ejection
Provides the sustained push force needed to eject compacted material bales from chamber-style balers, utilizing the full 628 mm stroke for complete ram extension.
Is the Airtac SC80 Standard Cylinder SC80X628 the Right Cylinder?
Choose the SC80X628 when your application needs around 2500 N of force at standard shop air. If you require less force, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa; for higher demands, the 100 mm bore SC100 delivers 3927 N at the same pressure.
For this 628 mm stroke, ensure the load is guided and side forces are minimal. Long unsupported strokes on a 25 mm rod are vulnerable to bending under side load—use an external guide rail or a guided cylinder if radial forces are present. When replacing an existing unit, match five points: 80 mm bore, 628 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and no magnet.
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 SC80X628 FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder and is shorter than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It replaces another AirTAC SC80 cylinder or a tie-rod cylinder matching the 80 mm bore, 628 mm stroke, PT3/8 ports, and basic mounting.
