About the Airtac SAI50 Standard Cylinder SAI50BX290
The AirTAC SAI50X290 is a double-acting ISO 15552 profile cylinder offering a 290mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of switches.

Where the Airtac SAI50 Standard Cylinder SAI50BX290 Is Used
Package Diverting
Provides the 982N push force needed to divert heavy packages on a sorting line.
Material Pressing
Ideal for securely pressing lightweight components into fixtures during assembly.
Pallet Positioning
Handles the 290mm travel required to index pallets into a wrapping station.
Is the Airtac SAI50 Standard Cylinder SAI50BX290 the Right Cylinder?
If you need less force, the 40mm bore provides 628N at 0.5 MPa; for heavier loads, the 63mm bore offers 1559N. Because this 290mm stroke exceeds the 300mm threshold, side loads can bend the unsupported rod and wear the bearing. Use an external guide rail or a guided cylinder to absorb lateral forces.
This model is dimensionally interchangeable per ISO 15552, allowing direct replacement with other standard profile cylinders. It uses a G1/4 port, an M16x1.5 rod thread, and 30mm adjustable cushions. If your application must hold a load without live air pressure, select the SAIL or BSAI locking variants instead.
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 SAI50 Standard Cylinder SAI50BX290 FAQ
At 0.5 MPa, this double-acting cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
Yes. It is a true ISO 15552 profile cylinder, meaning its mounting interface and dimensions are interchangeable with other ISO 15552 standard cylinders.
