About the Airtac SC80 Standard Cylinder SC80X300STC
The SC80X300STC is an 80 mm bore double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa (up to 4523 N at 0.9 MPa). Its 300 mm stroke combined with a 25 mm diameter piston rod and 28 mm adjustable air cushion makes it a robust mid-range actuator for general industrial automation.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC80TC). The trunnion allows the cylinder to pivot during operation, ideal for swinging or articulating loads. Standard PT1/4 ports and TPU seals rated for -20 to +70 °C complete the configuration.

Where the Airtac SC80 Standard Cylinder SC80X300STC Is Used
Conveyor Diverter Gates
The 300 mm stroke and centre trunnion pivot suit medium-reach diverter arms on packaging or sortation conveyors, where the cylinder swings to redirect product flow.
Clamping & Fixturing
With 2513 N of push force at standard line pressure, this cylinder provides ample clamping power for CNC fixtures, welding jigs, and assembly stations requiring consistent holding force.
Process Valve Actuation
The 80 mm bore delivers the thrust needed to operate quarter-turn ball or butterfly valves in water treatment, chemical dosing, or food processing lines, with sensor feedback via the built-in magnet.
Is the Airtac SC80 Standard Cylinder SC80X300STC the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore SC100 series provides 3927 N push at 0.5 MPa. If a lighter, more compact actuator is sufficient, the 63 mm bore SC63 series offers 1559 N at the same pressure. Always match replacement cylinders on five points: bore, stroke, port thread (PT), mounting accessory (TC with TCM1 bracket), and magnet option (-S).
At 300 mm stroke, the 25 mm rod is well-supported within standard limits, but avoid direct side loading. If the load applies lateral force or travels off-axis, use an external linear guide or switch to a guided cylinder to protect the rod bearing and piston seals from premature wear.
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 SC80X300STC FAQ
At 0.5 MPa air pressure, 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 at 1.0 MPa is 513 kgf.
Yes, if the original is an AirTAC SC series (or equivalent tie-rod cylinder) with an 80 mm bore, 300 mm stroke, PT1/4 ports, centre trunnion mount, and a magnetic piston for sensors. This model is not dimensionally interchangeable with ISO 15552 profile cylinders.
