About the Airtac SC80 Standard Cylinder SC80X270
The AirTAC SC80X270 double-acting pneumatic cylinder provides a robust 2513 N of push force at 0.5 MPa, scaling up to 4523 N at the maximum 0.9 MPa operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion are engineered to handle mid-range industrial loads with smooth deceleration, making the 270 mm stroke a practical choice for press and clamping applications.
With a compact body length of 182 mm and PT3/8 ports, this tie-rod cylinder is shorter than an ISO 15552 profile, saving space on the machine frame. The standard TPU seals offer reliable performance from -20 to +70 °C, and the variable cushion allows fine-tuning for your specific payload and speed.

Where the Airtac SC80 Standard Cylinder SC80X270 Is Used
Pallet Stop & Transfer
The 270 mm stroke and 2513 N push force at 0.5 MPa reliably stops and transfers pallets on conveyor lines, with the adjustable cushion absorbing impact for smooth, quiet operation.
Assembly Press
Delivers up to 4523 N at 0.9 MPa for pressing bearings, bushings, or pins. The 25 mm rod resists buckling under the high compressive forces of a press-fit operation.
Material Gate & Diverter
Actuates a diverter gate or chute in material handling. The 28 mm cushion length provides effective deceleration for the gate assembly, preventing metal-on-metal impact at the stroke end.
Is the Airtac SC80 Standard Cylinder SC80X270 the Right Cylinder?
For a 270 mm stroke, the SC80 bore gives a solid force floor of 2513 N at standard shop air. If your load is lighter and you need faster cycling, stepping down to an SC63 (1559 N at 0.5 MPa) can reduce air consumption. For heavier tooling, the SC100 delivers 3927 N at the same pressure. At this stroke length, ensure the rod is not exposed to significant side loads; an external guide or a guided cylinder is recommended to prevent rod bearing wear and bending.
When replacing an existing cylinder, match five points: 80 mm bore, 270 mm stroke, PT3/8 port thread, basic (no accessory) mounting, and no magnet. This model is a direct swap for another AirTAC SC80X270 tie-rod cylinder only.
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 SC80X270 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, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (182 mm for the SC80) than a comparable ISO 15552 profile cylinder. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same stroke, port thread, and mounting configuration.
