About the Airtac SAI80 Standard Air Cylinder SAI80X240S
The AirTAC SAI80X240-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 240mm stroke. It delivers a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa, making it well-suited for heavy-duty material handling and pressing tasks. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that resists mechanical wear.
Equipped with a magnet for position sensing, this model integrates seamlessly with CMSE and DMSE series switches mounted directly into the sensor grooves on both sides of the barrel. The standard carbon steel piston rod ensures high tensile strength for demanding cycles, while the adjustable air cushions at both ends deliver precise deceleration to minimize end-cap impact.

Where the Airtac SAI80 Standard Air Cylinder SAI80X240S Is Used
Heavy-Duty Pressing
Generates 2513 N of push force at 0.5 MPa, perfect for assembling bearings or stamping light metal components.
Pallet Diverting
The 240mm stroke provides the exact reach needed to push heavy pallets off a high-speed packaging conveyor line.
Automated Clamping
Securely holds large workpieces in CNC machining centers, utilizing the robust carbon steel rod for repeated high-force cycles.
Is the Airtac SAI80 Standard Air Cylinder SAI80X240S the Right Cylinder?
Selecting this 80mm bore over the smaller 63mm option (which provides 1559 N push at 0.5 MPa) is ideal when your application demands higher thrust without stepping up to the larger 100mm body. The 240mm stroke offers ample extension for mid-range automation tasks. Because the stroke is under 300mm, side-load stress on the rod bearing is moderate, but using a guided cylinder or external guide rails is still recommended if the load is heavy or off-center.
This model uses a G3/8 PT port thread and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions. Note that the standard double-acting configuration relies on continuous air pressure to hold position; if the air supply is lost, the piston will drift. For applications requiring true load holding upon pressure loss, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
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 SAI80 Standard Air Cylinder SAI80X240S FAQ
At an operating pressure of 0.5 MPa, this 80mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting and envelope dimensions are standardized, making it a drop-in replacement for other ISO 15552 cylinders from brands like Festo or SMC without altering the machine frame.
