About the Airtac SC80 Standard Cylinder SC80X725STC
The AirTAC SC80X725STC is a double-acting pneumatic cylinder delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, scaling up to 4523 N at the maximum operating pressure of 0.9 MPa. This model features an 80 mm bore with a 25 mm diameter piston rod, M20x1.5 rod thread, and a 28 mm adjustable air cushion at each end to decelerate the piston smoothly.
With a 725 mm stroke, the total extended body length reaches approximately 907 mm (body length A of 182 mm plus stroke). The -S suffix denotes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable position sensing. The TC suffix indicates a centre trunnion mount, supplied with the TCM1 bracket, which is ideal for applications where the cylinder body needs to pivot during operation.

Where the Airtac SC80 Standard Cylinder SC80X725STC Is Used
Conveyor Diverter Gates
The 725 mm stroke and pivoting trunnion mount allow this cylinder to operate large diverter gates on material handling lines, directing packages or bulk goods between multiple conveyor paths.
Welding Fixture Clamping
With 4523 N of clamping force at 0.9 MPa and a built-in magnet for end-of-stroke confirmation, it securely holds large automotive or structural steel assemblies in position during robotic welding.
Agricultural Equipment Actuation
The long 725 mm stroke and robust 25 mm rod are suited for remote actuation of chutes, hopper doors, or sprayer boom folds on heavy-duty agricultural machinery.
Is the Airtac SC80 Standard Cylinder SC80X725STC the Right Cylinder?
Select the SC80 bore 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 725 mm stroke, ensure the rod is protected from side loads; an external guide rail or a guided cylinder should be used to prevent rod bending and premature bearing wear. The centre trunnion mount (TC) allows the cylinder to swing, accommodating angular movement in the load path.
For a direct replacement, match these five points exactly: 80 mm bore, 725 mm stroke, PT1/4 port thread, centre trunnion (TC) mounting with the F-SC80TC bracket, and the built-in magnet (-S) for sensor compatibility. This is a tie-rod cylinder 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 SC80X725STC FAQ
At the standard 0.5 MPa operating pressure, this cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so it is not dimensionally interchangeable. It will only directly replace another AirTAC SC tie-rod cylinder with the same 80 mm bore, 725 mm stroke, PT ports, centre trunnion mount, and built-in magnet.
