About the Airtac SC80 Standard Cylinder SC80X65LB
The SC80X65LB is an 80 mm bore, 65 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 reaches 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model is factory-configured with an LB foot mounting bracket (F-SC80LB), providing a stable axial base for surface mounting. The 65 mm stroke is a standard length within the 1500 mm maximum for this bore, and the cylinder body length A measures 182 mm. The adjustable pneumatic cushion at each end decelerates the piston over a 28 mm distance to reduce end-of-stroke impact.

Where the Airtac SC80 Standard Cylinder SC80X65LB Is Used
Packaging Press
The 2513 N push force at 0.5 MPa suits medium-duty pressing and clamping in packaging lines, with the LB foot mount securing the cylinder to a machine bed.
Material Stamping
Delivers up to 4523 N at 0.9 MPa for light stamping or forming operations. The 25 mm rod and 28 mm cushion absorb shock during high-cycle punching.
Conveyor Diverting
The 65 mm stroke is ideal for short-throw diverters and gates. The foot mount enables easy integration onto conveyor side frames for package sorting.
Is the Airtac SC80 Standard Cylinder SC80X65LB the Right Cylinder?
Select the SC80 bore when your application needs between 2513 N and 4523 N of pneumatic force. If your load requires less, stepping down to the SC63 bore provides 1559 N at 0.5 MPa in a more compact 153 mm body length. For higher force, the SC100 delivers 3927 N at the same pressure.
To ensure a correct replacement, match five key points: 80 mm bore, 65 mm stroke, PT3/8 port thread, LB foot mounting (F-SC80LB), and the absence of a magnet. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. For strokes over 300 mm, consider an external guide to protect the rod bearing from side loads.
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 SC80X65LB FAQ
At 0.5 MPa the cylinder pushes with 2513 N and pulls with 2268 N. At 0.7 MPa push force is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than an ISO 15552 profile cylinder, so the mounting dimensions and body length will not match. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same stroke, port, and LB foot mount.
