About the Airtac SC80 Standard Cylinder SC80X938
The AirTAC SC80X938 is a double-acting tie-rod cylinder with an 80 mm bore and a 938 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide reliable deceleration for mid-to-long linear movements in pneumatic systems.
With a body length A of 182 mm, the total extended length reaches 1120 mm, making it suitable for applications requiring a significant reach. The standard PT3/8 port and M20x1.5 rod thread ensure straightforward integration, while the TPU seals maintain a standard operating range of -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X938 Is Used
Long-Reach Material Transfer
Pushes or pulls heavy bins and totes across wide roller conveyors, using its 938 mm stroke to bridge large gaps between processing stations.
Automated Panel Pressing
Applies consistent clamping force over a long travel distance in woodworking or composite layup fixtures, where the 4523 N maximum thrust ensures solid adhesion.
Pallet Dispenser Actuation
Extends to lift or separate pallets in an automated dispenser, leveraging the 80 mm bore's force to handle stacked loads reliably in logistics centers.
Is the Airtac SC80 Standard Cylinder SC80X938 the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force. If your load requires less force, consider stepping down to the SC63 bore (1559 N at 0.5 MPa) for a more compact footprint. For higher force demands, the SC100 bore provides 3927 N at 0.5 MPa.
For this 938 mm stroke, side-load management is critical. The long, unsupported 25 mm rod is susceptible to bending under lateral forces. Always guide the load externally with linear rails or rods, or consider a guided cylinder assembly to protect the rod bearing and seals from premature wear. When replacing this cylinder, match the 80 mm bore, 938 mm stroke, PT3/8 port thread, basic mount, and ensure the magnet option matches 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 SC80X938 FAQ
At the standard operating pressure of 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.
For strokes of 300 mm or more, never allow the rod to experience unguided side loads. Install an external guide system (such as hardened shafts and linear bearings) parallel to the cylinder to absorb all lateral forces, ensuring only axial force is transmitted to the rod bearing and piston seals.
