About the Airtac SC80 Standard Cylinder SC80X1120S
The AirTAC SC80X1120S is a double-acting tie-rod cylinder with an 80 mm bore and a long 1120 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 are designed to manage the inertia of large, fast-moving loads.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The standard PT1/8 port and TPU seals suit general industrial air service from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X1120S Is Used
Long-Reach Part Transfer
The 1120 mm stroke and 2513 N push force move heavy components between distant conveyor stations, with the built-in magnet providing end-of-stroke confirmation.
Pallet Dispenser Actuation
Pushes tall stacks of pallets or bins in automated storage systems. The adjustable cushion decelerates the high-inertia load smoothly at the end of the long travel.
Large Panel Clamping
Extends across wide jigs to clamp large wooden or composite panels for CNC routing, using sensor feedback from the -S magnet to interlock with the machine cycle.
Is the Airtac SC80 Standard Cylinder SC80X1120S the Right Cylinder?
Select the SC80 for applications needing 2513 N of push force at 0.5 MPa. If your load requires more force, step up to the SC100 bore, which provides 3927 N at the same pressure. For a lighter, more compact solution, the SC63 bore offers 1559 N.
For this 1120 mm stroke, carefully evaluate side loads. A long, unsupported 25 mm rod is susceptible to bending under lateral force. Use an external linear guide or a guided cylinder to absorb side loads and protect the rod bearing and piston seals. When replacing, match bore (80 mm), stroke (1120 mm), PT port thread, the built-in magnet (-S), and the basic mounting configuration.
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 SC80X1120S 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.
This cylinder uses a 25 mm diameter rod. For a stroke of 1120 mm, you must ensure the load is purely axial. Any side load can cause rod deflection and premature seal wear. Mount the load on an external linear guide rail, or use a rod clevis with a spherical bearing to avoid transmitting bending moments to the cylinder.
