About the Airtac SC80 Standard Cylinder SC80X750STC
The SC80X750STC is an 80 mm bore, 750 mm stroke double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion are engineered for reliable mid-range automation tasks requiring a balance of force and speed.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC80TC), allowing the cylinder to pivot during operation. The total extended body length is approximately 932 mm, making it suitable for applications with a defined swing plane.

Where the Airtac SC80 Standard Cylinder SC80X750STC Is Used
Material Handling Diverters
The 750 mm stroke and pivoting trunnion mount are ideal for pusher arms on conveyor lines, diverting packages or products onto branching lanes with controlled force.
Clamping & Welding Fixtures
Provides up to 4523 N of clamping force at 0.9 MPa. The centre trunnion allows the clamp arm to swing clear for easy part loading and unloading in fabrication cells.
Agricultural Gate & Chute Actuation
With its long stroke and high force, this cylinder reliably opens and closes heavy chute gates or hopper doors on agricultural processing equipment, with sensor feedback for position confirmation.
Is the Airtac SC80 Standard Cylinder SC80X750STC the Right Cylinder?
For applications needing less force, consider stepping down to a 63 mm bore (1559 N at 0.5 MPa). If higher force is required, the 100 mm bore provides 3927 N at the same pressure. At a 750 mm stroke, the piston rod is extended significantly; ensure side loads are minimized or use an external guide system to prevent rod bending and premature bearing wear.
To replace an existing cylinder, match these five points exactly: 80 mm bore, 750 mm stroke, PT port thread, centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
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 SC80X750STC FAQ
The theoretical push force is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the return stroke is 2268 N at 0.5 MPa due to the 25 mm rod diameter.
Yes. The -S suffix indicates a built-in magnet on the piston. This allows you to clamp compatible CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the cylinder barrel to detect end-of-stroke or intermediate positions.
