About the Airtac SC80 Standard Cylinder SC80X300SCB
The SC80X300SCB is an 80 mm bore, 300 mm stroke double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa. This model includes a built-in magnet for mounting CMSG/DMSG/EMSG sensors and a rear CB double clevis (fork) mount for pivoting applications, using the F-SC80CB bracket.
With a 25 mm diameter piston rod and an adjustable air cushion length of 28 mm, it reliably decelerates end-of-stroke loads. The cylinder body length A is 182 mm, giving a total extended length of approximately 482 mm. At the maximum operating pressure of 0.9 MPa, it generates up to 4523 N of thrust, making it a robust choice for medium-duty industrial tasks.

Where the Airtac SC80 Standard Cylinder SC80X300SCB Is Used
Pivoting Conveyor Gates
The rear CB clevis mount allows the cylinder body to pivot, making it ideal for actuating diverter gates on conveyor systems where the 300 mm stroke provides a wide sorting angle.
Clamping & Fixturing
Delivers up to 4523 N of clamping force at 0.9 MPa. The integrated magnet enables end-of-stroke sensing to confirm part clamping before a machining cycle starts.
Press & Forming Assist
Suitable for light-duty press mechanisms requiring a 300 mm stroke. The 28 mm adjustable cushion smoothly decelerates the 25 mm rod, reducing impact noise and vibration.
Is the Airtac SC80 Standard Cylinder SC80X300SCB the Right Cylinder?
Select the SC80X300SCB when your application requires a 300 mm stroke with 2513 N of force at standard plant pressure. If you need higher force, consider stepping up to the SC100 bore, which provides 3927 N at 0.5 MPa; for a lighter, more compact solution, the SC63 bore offers 1559 N. This 300 mm stroke model requires careful alignment to prevent side-loading on the 25 mm rod; for unsupported loads, use an external linear guide.
For direct replacement, match these five specifications exactly: 80 mm bore, 300 mm stroke, PT port thread, rear CB double clevis mounting, and the built-in magnet (-S) for sensor compatibility. The SC 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 SC80X300SCB FAQ
At 0.5 MPa, 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. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X300SCB is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. You must add a pilot-operated check valve or an external mechanical rod lock for static load holding.
