About the Airtac SAI32 Standard Cylinder SAI32X290S
The AirTAC SAI32X290-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 290mm stroke. It generates 402N of push force at 0.5 MPa, extending to 563N at 0.7 MPa, making it well-suited for mid-distance linear actuation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 standard cylinders.
This specific configuration includes a magnet for proximity sensing, allowing seamless integration with CMSE and DMSE switches mounted into the dual-side sensor grooves. It utilizes standard carbon steel for the piston rod and features PT (tapered) threaded ports. The integrated adjustable air cushions at both ends ensure smooth end-of-stroke deceleration for moving loads.

Where the Airtac SAI32 Standard Cylinder SAI32X290S Is Used
Package Sorting
Ideal for pushing light to medium-weight packages on a 290mm sorting lane, utilizing the magnet and CMSE sensors for stroke confirmation.
Small Part Ejection
Provides reliable 563N push force at 0.7 MPa to eject machined small parts from a fixture over a mid-range distance.
Pallet Diverting
Actuates lightweight diverting arms in conveyor systems where a 290mm extension is needed to redirect small product flow.
Is the Airtac SAI32 Standard Cylinder SAI32X290S the Right Cylinder?
Selecting this 32mm bore cylinder is ideal when an application requires 402N (at 0.5 MPa) of push force over a 290mm travel distance. If your project demands greater thrust, stepping up to the 40mm bore yields 628N at 0.5 MPa. Because the 290mm stroke exceeds the 300mm threshold, it is critical to manage side loads; an unsupported rod of this length can bend under lateral forces. Utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model serves as a direct replacement for any ISO 15552 cylinder with matching 32mm bore, 290mm stroke, and G1/8 port dimensions. To complete your assembly, pair it with compatible mounting accessories like FA flanges or LB foot brackets, and ensure you order the -S magnet variant if position feedback is required. Note that this cylinder relies on live air pressure to hold position; it will drift if pressure is lost, so consider the SAIL variant if mechanical locking is needed.
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 SAI32 Standard Cylinder SAI32X290S FAQ
At a standard operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563N.
Yes, the SAI32X290-S is a true ISO 15552 profile cylinder. Its mounting dimensions, 32mm bore, 290mm stroke, and G1/8 port make it dimensionally interchangeable with other ISO 15552 cylinders, serving as a direct replacement.
