About the Airtac SC80 Standard Cylinder SC80X75FB
The SC80X75FB is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining an 80 mm bore with a 75 mm standard stroke. This model delivers a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with an M20x1.5 rod thread.
Configured with an FB rear rectangular flange (mounting accessory F-SC80FB), this cylinder is designed for rigid end-face mounting onto machine panels or bulkheads. The body length A is 182 mm, and the adjustable air cushion at each end is 28 mm long, providing smooth deceleration for the moving load.

Where the Airtac SC80 Standard Cylinder SC80X75FB Is Used
Packaging Machine Pusher
The 75 mm stroke and 2513 N force at 0.5 MPa are ideal for diverting cartons or products on a conveyor line, with the FB rear flange providing a rigid, fixed mounting point.
Clamping & Fixturing
Delivers a controlled 4523 N clamping force at 0.9 MPa for holding workpieces during machining or assembly, with the rear flange ensuring stable alignment.
Press & Forming Assist
Suitable for light pressing or forming operations where a short, powerful linear stroke is needed, leveraging the 25 mm rod's strength and the cylinder's adjustable cushioning.
Is the Airtac SC80 Standard Cylinder SC80X75FB the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N of push force at 0.5 MPa. If space is a constraint, the 63 mm bore SC63 series offers 1559 N at the same pressure. The 75 mm stroke on this model is well within the 1500 mm maximum standard stroke for the 80 mm bore.
To ensure a direct replacement, match five key points: the 80 mm bore, 75 mm stroke, PT port thread, FB rear flange mounting, and the absence of a magnet. This cylinder uses PT1/8 ports and a TPU seal, rated for a standard temperature range of -20 to +70 °C.
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 SC80X75FB 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.
Yes, provided the original is an AirTAC SC tie-rod cylinder or an equivalent with matching specifications. Verify the bore (80 mm), stroke (75 mm), PT port thread, FB rear flange mounting, and that no magnet is required. The SC series is not dimensionally interchangeable with ISO 15552 cylinders.
