About the Airtac SC80 Standard Cylinder SC80X275
The SC80X275 is an 80 mm bore, 275 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. At 0.5 MPa it generates 2513 N pushing and 2268 N pulling, stepping up to 4523 N at the maximum operating pressure of 0.9 MPa. The 25 mm diameter piston rod and 28 mm air cushion provide robust deceleration for mid-range automation tasks.
This cylinder uses a PT3/8 port and a body length A of 182 mm, giving a total extended length of approximately 457 mm. The adjustable cushion at both ends lets you tune end-of-stroke braking for smooth, quiet operation. It is built with standard TPU seals for a -20 to +70 °C working range and comes in a basic configuration without magnet or mounting accessories, ready for direct integration.

Where the Airtac SC80 Standard Cylinder SC80X275 Is Used
Package Diverting
The 275 mm stroke pushes cartons off a main conveyor onto a spur line. The 2513 N force at 0.5 MPa handles heavy boxes reliably, and the adjustable cushion reduces impact noise at the end of travel.
Clamping & Fixturing
Used in a welding or assembly jig, this cylinder applies up to 4523 N of clamping force at 0.9 MPa. The tie-rod construction allows easy maintenance in harsh, high-cycle production environments.
Pallet Stop Gate
Mounted at the end of a gravity roller lane, the SC80X275 raises and lowers a stop gate. The 25 mm rod and 28 mm cushion absorb the kinetic energy of a moving pallet without jarring the structure.
Is the Airtac SC80 Standard Cylinder SC80X275 the Right Cylinder?
For higher force, the 100 mm bore SC100 series offers 3927 N at 0.5 MPa. If space is tight and 80 mm is the maximum diameter, verify that the 275 mm stroke does not create excessive side load on the 25 mm rod; strokes above 300 mm on an unsupported rod can cause bending. Consider an external guide or a guided cylinder for off-axis loads.
When replacing an existing unit, match five points: 80 mm bore, 275 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and no magnet. This ensures the SC80X275 drops into the same envelope as another AirTAC SC tie-rod cylinder of identical specification.
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 SC80X275 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf (5027 N).
This specific model (SC80X275) does not include the -S magnet option, so the piston does not carry a magnetic ring. CMSG/DMSG/EMSG sensors cannot be used. If you need position sensing, order the SC80X275-S variant which has a built-in magnet.
