About the Airtac SC80 Standard Cylinder SC80X740S
The AirTAC SC80X740S is a double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. With an 80 mm bore and a 740 mm stroke, it features a 25 mm diameter piston rod and an adjustable air cushion length of 28 mm to decelerate end-of-stroke impact smoothly.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable position feedback. The total extended body length is approximately 922 mm, making it a robust choice for medium-to-long linear movements in industrial automation.

Where the Airtac SC80 Standard Cylinder SC80X740S Is Used
Material Transfer
Pushes or lifts heavy totes and pallets on roller conveyors, using the 2513 N force at 0.5 MPa to reliably move loads in distribution centers.
Clamping & Pressing
Provides up to 4523 N of clamping force at 0.9 MPa for holding workpieces during welding, assembly, or light press-fit operations.
Bin Diverter Gate
Actuates a diverter gate in chutes or hoppers, with the 740 mm stroke offering the reach needed for wide sorting lanes and the magnet sensor confirming gate position.
Is the Airtac SC80 Standard Cylinder SC80X740S the Right Cylinder?
Select the SC80 when your application requires a force between the SC63 (1559 N push at 0.5 MPa) and the SC100 (3927 N push at 0.5 MPa). For this 740 mm stroke, ensure the rod is not subjected to high side loads; an external guide rail or a guided cylinder is recommended to prevent rod bending and premature bearing wear over long unsupported extensions.
For a direct replacement, match five key points: bore (80 mm), stroke (740 mm), port thread (PT 3/8), the built-in magnet for sensors (-S), and the basic mounting style. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X740S 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. The -S suffix indicates a built-in magnet in the piston, making this cylinder compatible with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors that clamp directly onto the barrel tie-rods.
