About the Airtac SC80 Standard Cylinder SC80X345
The SC80X345 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 345 mm stroke, its 25 mm diameter piston rod provides robust linear motion for medium-to-heavy automation tasks.
This model features an adjustable air cushion (28 mm length) at both ends to decelerate the piston smoothly, reducing impact and noise. The total extended body length is approximately 527 mm (182 mm body length A + 345 mm stroke). Ports are PT3/8, and the rod thread is M20x1.5, ready for direct tooling attachment.

Where the Airtac SC80 Standard Cylinder SC80X345 Is Used
Material Handling Pushers
The 345 mm stroke and 2513 N force at 0.5 MPa are ideal for diverting packages or products off a conveyor line, providing a firm, repeatable push.
Clamping & Assembly Fixtures
Delivers a controlled 4523 N clamping force at 0.9 MPa for holding workpieces during welding, gluing, or machining operations.
Palletising & Lifting Aids
Suitable for vertical lifting of moderate loads in palletisers, where the 2268 N pull force at 0.5 MPa retracts a gate or stop with reliability.
Is the Airtac SC80 Standard Cylinder SC80X345 the Right Cylinder?
Select the SC80X345 when your application requires a force step up from the 50 mm bore (982 N push at 0.5 MPa) but does not yet demand the 100 mm bore's 3927 N output. For this 345 mm stroke, ensure side loads are minimal or use an external guide; the unsupported 25 mm rod can experience bending stress under significant lateral force.
To replace an existing cylinder, match five points exactly: 80 mm bore, 345 mm stroke, PT3/8 port thread, basic mounting (no bracket), and confirm whether a magnet is needed (this model has no built-in magnet). The SC 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 SC80X345 FAQ
At the standard 0.5 MPa operating pressure, 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 increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X345 is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston will drift or drop under load. For load-holding safety, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
