About the Airtac SC80 Standard Cylinder SC80X1270
The SC80X1270 is an AirTAC SC series double-acting tie-rod cylinder with an 80 mm bore and a 1270 mm stroke, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide reliable deceleration for medium-to-long stroke linear movements.
This cylinder features a body length A of 182 mm, resulting in a total extended length of approximately 1452 mm. With a PT3/8 port and standard TPU seals, it operates from -20 to +70 °C. For long-stroke applications, external guides are recommended to protect the rod from side loads.

Where the Airtac SC80 Standard Cylinder SC80X1270 Is Used
Long-Reach Material Transfer
The 1270 mm stroke is ideal for pushers or transfer arms on wide conveyors, moving products between parallel lines with the 2513 N force at standard plant pressure.
Automated Panel Tipping
Provides the long linear travel needed to tip large panels or sheets from a stack onto a processing line, with adjustable cushioning to control the motion at end-of-stroke.
Pallet Dispensing Systems
Deploy this cylinder in pallet magazine dispensers where a long, steady stroke is required to push a single pallet from the bottom of a stack onto a roller bed.
Is the Airtac SC80 Standard Cylinder SC80X1270 the Right Cylinder?
Choose the SC80 bore for push forces around 2513 N at 0.5 MPa. If your force requirement is lower, the SC63 bore provides 1559 N at the same pressure in a smaller package. For higher forces, step up to the SC100 bore which delivers 3927 N at 0.5 MPa. Ensure the 1270 mm stroke is within the 1500 mm maximum standard stroke for this bore.
For this 1270 mm stroke, the extended 25 mm rod is susceptible to bending under side loads. Always use an external linear guide or rod support to prevent bearing damage and ensure long service life. When replacing, match bore, stroke, PT3/8 port thread, basic mounting, and the optional magnet configuration.
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 SC80X1270 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.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port thread.
