About the Airtac SC80 Standard Cylinder SC80X72
The SC80X72 is an 80 mm bore, 72 mm stroke double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 25 mm diameter piston rod and 28 mm adjustable air cushion make it a solid mid-range actuator for general industrial tasks.
This model uses the standard TPU/NBR seal package rated for -20 to +70 °C and PT3/8 ports. With a body length A of 182 mm, the total extended length is approximately 254 mm, fitting compact spaces where a genuine AirTAC tie-rod cylinder is specified.

Where the Airtac SC80 Standard Cylinder SC80X72 Is Used
Package Diverting
The 72 mm stroke and quick 30-800 mm/s speed range suit lightweight package diverters on belt conveyors, where the 2513 N push at 0.5 MPa easily shifts cartons.
Clamping & Fixturing
Delivers a firm, controlled clamp stroke for woodworking or metal fab jigs. The adjustable cushion protects the fixture from hammering at end-of-stroke.
Press-Fit Assembly
Generates up to 4523 N of push force at 0.9 MPa for pressing bushings or bearings into housings on a short, guided insertion stroke.
Is the Airtac SC80 Standard Cylinder SC80X72 the Right Cylinder?
Choose the SC80 when the SC63’s 1559 N push at 0.5 MPa is marginal—the 80 mm bore steps up to 2513 N without increasing plant air pressure. If the load is lighter, dropping to the SC63 saves space and air consumption. For any stroke, match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory, and magnet option.
At 72 mm this is a short-stroke application, but if your design later moves to a stroke of 300 mm or longer on this 80 mm bore, watch for side loads. Long, unsupported rods can bend under off-axis force; add an external guide rail or switch to a guided cylinder to protect the rod bearing and seal.
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 SC80X72 FAQ
At the standard 0.5 MPa operating pressure, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force rises to 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so dimensions and mounting points are not interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread, and mounting style.
