About the Airtac SC80 Standard Cylinder SC80X625STC
The SC80X625STC is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 625 mm stroke is well within the 1500 mm maximum standard stroke for this bore, making it a standard-configuration actuator for medium-to-long linear movements.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC suffix, supplied with the TCM1 bracket, part code F-SC80TC) that allows the cylinder to pivot during operation. The 25 mm diameter piston rod and 28 mm adjustable air cushion at each end provide robust guidance and smooth end-of-stroke deceleration.

Where the Airtac SC80 Standard Cylinder SC80X625STC Is Used
Conveyor Diverter Gates
The 625 mm stroke and pivoting trunnion mount suit medium-reach diverter arms on packaging or sorting conveyors, where the cylinder body needs to swing through an arc.
Clamp & Fixture Actuation
With 4523 N of force at 0.9 MPa and sensor-ready position feedback, this cylinder securely clamps large weldments or wood panels in automated jigs.
Hopper Gate Control
The robust 25 mm rod and centre-trunnion pivot handle the repetitive sliding motion of a material hopper gate, while the magnet allows end-of-travel confirmation.
Is the Airtac SC80 Standard Cylinder SC80X625STC the Right Cylinder?
Select the SC80 when your application needs roughly 2500 N of force at standard plant air pressure. If your load is lighter, stepping down to a 63 mm bore reduces push force to 1559 N at 0.5 MPa; for heavier loads, the 100 mm bore provides 3927 N at the same pressure. The 625 mm stroke is a standard length, but always confirm that the rod is adequately supported against side loads—at this extended length, an external guide or a guided cylinder may be necessary to prevent rod bending.
For a direct replacement, match five key attributes: 80 mm bore, 625 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X625STC FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. You must replace it with another AirTAC SC80 tie-rod cylinder matching the bore, stroke, PT port, TC mount, and magnet option.
