About the Airtac SC80 Standard Cylinder SC80X270FA
The SC80X270FA is an 80 mm bore, 270 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a substantial push force of 2513 N at 0.5 MPa (4523 N at the maximum operating pressure of 0.9 MPa), making it a robust choice for medium-to-heavy industrial linear motion tasks.
This specific configuration ships with a front rectangular flange (mounting code FA, part F-SC80FA) for rigid panel or bulkhead mounting. The 25 mm diameter piston rod provides excellent rigidity for the 270 mm extension, and the 28 mm adjustable air cushion at each end ensures smooth, high-speed deceleration. Ports are PT3/8 with an M20x1.5 rod thread.

Where the Airtac SC80 Standard Cylinder SC80X270FA Is Used
Material Transfer Gates
The 270 mm stroke and front flange mount allow direct attachment to a panel for diverting medium-weight packages or parts on a conveyor line with a 2513 N push.
Press-Fit Assembly Fixtures
Delivers a controlled 4523 N of force at 0.9 MPa for pressing bearings or bushings into housings, with the FA flange ensuring precise alignment to the fixture plate.
Tensioning and Clamping Stations
Ideal for applying consistent pull or clamp force in a web tensioning system, where the front flange mounts the cylinder body securely to the machine frame.
Is the Airtac SC80 Standard Cylinder SC80X270FA the Right Cylinder?
For applications requiring a rigid, end-face mounting solution, the FA front flange is ideal. If your force requirement is slightly lower, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. For higher demands, stepping up to the 100 mm bore SC100 series delivers 3927 N at the same pressure.
At a 270 mm stroke, the 25 mm rod is well-supported, but always avoid direct side loading. If the load path is not perfectly axial, use an external linear guide to protect the rod bearing and seals. For a direct replacement, match the 80 mm bore, 270 mm stroke, PT3/8 ports, FA front flange mount, and ensure the non-magnetic piston is correct for your sensor setup.
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 SC80X270FA 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.
No, the FA configuration is a fixed, front rectangular flange mount designed for rigid, non-pivoting installation. For a pivoting application, select a model with a TC centre trunnion or CA/CB rear clevis mount.
