About the Airtac SAI80 Standard Air Cylinder SAI80BX290
The AirTAC SAI80X290 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513 N of push force at 0.5 MPa. With an 80 mm bore and 290 mm stroke, it is built for heavy-duty automation tasks requiring substantial mid-stroke displacement. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in wet or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it operates without integrated position sensing. Adjustable air cushions at both ends absorb kinetic energy to protect the mechanism across its 30-800 mm/s operating speed range.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX290 Is Used
Heavy Stamping
Provides the 2513 N push force necessary to actuate heavy stamping presses and form metal components reliably.
Pallet Diversion
Handles the 290 mm stroke to push heavy pallets off a main conveyor line onto secondary packaging tracks.
Material Forming
Utilizes the SUS304 stainless steel rod to operate clamping and forming fixtures in humid or mildly corrosive factory settings.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX290 the Right Cylinder?
Selecting this 80 mm bore unit makes sense when the 1402 N pull force at 0.5 MPa meets your load requirement, but stepping up to a 100 mm bore provides a significant increase to 3681 N pull for heavier dynamics. Because this model has a 290 mm stroke, it approaches the threshold where side loads can induce bending stresses on the piston rod and front bearing. Implementing an external guide rail or choosing a fully guided cylinder is strongly recommended to prevent premature wear and rod deflection.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other standard profile cylinders matching the 80 mm bore, 290 mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Note that standard double-acting cylinders drift when air pressure is removed; if your application requires static load holding upon pressure loss, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
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 SAI80BX290 FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X290 adheres strictly to ISO 15552 mounting dimensions, making it a direct replacement for any standard 80 mm profile cylinder with a 290 mm stroke, G3/8 ports, and compatible accessories.
