About the Airtac SC80 Standard Cylinder SC80X300S
The SC80X300S is a double-acting, single-rod tie-rod cylinder delivering 2513 N of push force at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 300 mm stroke, this actuator uses a 25 mm diameter rod and PT3/8 ports, providing a robust platform for medium-duty linear motion tasks.
This model includes the factory-installed -S magnet embedded in the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the barrel for precise end-of-stroke or mid-stroke position sensing. The standard TPU seals ensure reliable operation in a temperature range of -20 to +70 °C, while the adjustable pneumatic cushion at each end, with a 28 mm cushion length, decelerates the piston to reduce end-of-stroke impact.

Where the Airtac SC80 Standard Cylinder SC80X300S Is Used
Sensor-Monitored Part Transfer
The built-in magnet enables precise position feedback for diverting or transferring products on a conveyor line, ensuring the cylinder has fully extended or retracted before the next cycle begins.
Automated Clamping & Fixturing
Delivers a strong, controlled clamping force for CNC machining or welding fixtures, with magnetic sensors confirming the clamp is engaged to interlock with the machine's safety system.
Packaging & Palletizing Pushers
Provides the 2513 N push needed to square cases or push cartons onto a pallet, while the sensor confirms retraction to prevent jams in high-cycle packaging machinery.
Is the Airtac SC80 Standard Cylinder SC80X300S the Right Cylinder?
Select the SC80X300S when your application requires a force class of roughly 2500 N at standard plant air pressure. If your load demands more force, stepping up to the SC100 bore provides 3927 N of push at 0.5 MPa; for a lighter, more compact solution, the SC63 bore delivers 1559 N. With a 300 mm stroke, the 25 mm rod is well-supported, but any significant side loading or misalignment in the mounting should be managed with an external guide or a self-guided actuator to prevent premature rod bearing and seal wear.
To replace an existing cylinder, confirm five key points: an 80 mm bore, a 300 mm stroke, PT3/8 port threads, the basic (no bracket) mounting configuration, and the presence of a piston magnet for sensors. This genuine AirTAC SC tie-rod cylinder is shorter than an ISO 15552 profile cylinder and will only interchange dimensionally with another AirTAC SC80 unit of the same configuration.
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 SC80X300S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder generates a theoretical push force of 2513 N and a pull force of 2268 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The maximum theoretical force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code SC80X300S indicates a built-in magnet in the piston assembly. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel's external tie-rod slots to detect piston position without any additional brackets.
