About the Airtac SC80 Standard Cylinder SC80X290
The AirTAC SC80X290 is a double-acting pneumatic cylinder delivering a substantial 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa). Its 80 mm bore and 290 mm stroke suit medium-duty linear tasks where a compact tie-rod body is preferred.
This model features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm adjustable air cushion at each end to decelerate the load smoothly. The total extended body length is approximately 472 mm (182 mm body length A + 290 mm stroke), making it a space-efficient choice for genuine AirTAC performance.

Where the Airtac SC80 Standard Cylinder SC80X290 Is Used
Package Diverting
The 290 mm stroke and 2500 N push force reliably shift cartons or totes on conveyor lines, with the adjustable cushion protecting the cylinder from impact wear during high-cycle diverting.
Clamping & Fixturing
Generates over 4500 N of clamping force at 0.9 MPa for holding workpieces during machining or welding. The tie-rod construction allows easy maintenance in demanding production cells.
Grain Gate Actuation
Operates slide gates or chute diverters in agricultural handling. The PT3/8 ports and filtered-air requirement ensure reliable service in dusty environments when properly maintained.
Is the Airtac SC80 Standard Cylinder SC80X290 the Right Cylinder?
Choose the SC80X290 when your application needs around 2500 N of force at standard shop air. If you require more thrust, step up to the SC100 bore (3927 N at 0.5 MPa); for a lighter, faster actuator, the SC63 delivers 1559 N at the same pressure. At 290 mm stroke, side-loading on the 25 mm rod should be avoided—use an external guide or linear rail if the load is not purely axial.
For a direct replacement, match five points: 80 mm bore, 290 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and confirm the magnet option (this code has no 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 SC80X290 FAQ
At 0.5 MPa the 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 SC80X290 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
