About the Airtac SAI32 Standard Cylinder SAI32BX250
The AirTAC SAI32X250 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force at 0.5 MPa. With a 250 mm stroke, it is well-suited for mid-length indexing and compact automation tasks. The extruded aluminum barrel omits tie rods for a clean exterior.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external switches; adding the -S option enables CMSE or DMSE sensors via the dual side grooves.

Where the Airtac SAI32 Standard Cylinder SAI32BX250 Is Used
Compact Assembly Ejection
Provides reliable 402 N push force at 0.5 MPa to eject small finished components from machining centers.
Package Routing Diverter
Utilizes the 250 mm stroke to extend and route lightweight cardboard packaging across conveyor belts.
Small Part Lift Gate
Actuates lifting gates for low-weight material handling stations using its SUS304 rod to resist environmental moisture.
Is the Airtac SAI32 Standard Cylinder SAI32BX250 the Right Cylinder?
If your application requires less extension force, stepping down is not an option at the 32 mm bore size, but moving up to a 40 mm bore increases the 0.5 MPa push force to 628 N. For this 250 mm stroke, the unsupported rod length is moderate, but operators should still ensure axial load alignment to prevent rod-bearing wear.
This model serves as a dimensionally interchangeable direct replacement per ISO 15552 mounting dimensions. It uses a G1/8 port, accepts standard FA/FB flanges or TC trunnions, and requires the -S magnet suffix if pneumatic positioning sensors are needed. Note that a standard SAI does not hold loads safely upon air loss; integrate an external pilot check valve if dropping poses a hazard.
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 SAI32BX250 FAQ
At 0.5 MPa operating pressure, the SAI32X250 generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X250 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface and 32 mm bore dimensions as other standard ISO 15552 profile cylinders.
