About the Airtac SC80 Standard Cylinder SC80X650FA
The SC80X650FA is an 80 mm bore, 650 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a solid choice for medium-duty linear tasks. The 25 mm diameter piston rod and 28 mm air cushion provide robust, quiet end-of-stroke deceleration.
This model includes an FA front rectangular flange (part F-SC80FA) for secure panel or bulkhead mounting. The body length A is 182 mm, giving a total extended length of approximately 832 mm. Standard PT1/8 ports and TPU seals suit a -20 to +70 °C operating range.

Where the Airtac SC80 Standard Cylinder SC80X650FA Is Used
Part Transfer
The 650 mm stroke and front flange mount suit conveyor diverters and pushers, moving totes or packages between lines with the 2513 N force available at standard shop air.
Clamping & Pressing
Delivers up to 4523 N of clamping force at 0.9 MPa for holding workpieces in CNC fixtures or assembly jigs, with the adjustable cushion preventing impact shock.
Hopper Gate Actuation
Operates slide gates on bulk material hoppers. The 25 mm rod handles the repetitive sliding load, and the front flange simplifies mounting to the gate frame.
Is the Airtac SC80 Standard Cylinder SC80X650FA the Right Cylinder?
Choose the SC80 for 2513 N of push force at 0.5 MPa. If your load is lighter, stepping down to a 63 mm bore reduces force to 1559 N; for heavier loads, the 100 mm bore provides 3927 N. Always match the bore, 650 mm stroke, PT port thread, and FA front flange mount when replacing an existing unit.
At 650 mm stroke, the rod is fully supported by the front bushing, but any significant side load can cause rod bending or premature bearing wear. For applications with off-axis forces, consider pairing the cylinder with an external linear guide or switching to a guided cylinder assembly to protect the rod and seals.
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 SC80X650FA FAQ
At 0.5 MPa, the push force is 2513 N. At the maximum operating pressure of 0.9 MPa, it reaches 4523 N. The theoretical force at 1.0 MPa is 513 kgf.
No. The SC is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder (body A is 182 mm). It is not dimensionally interchangeable. Only use it to replace another AirTAC SC80 tie-rod cylinder with matching bore, stroke, PT ports, and FA front flange mount.
