About the Airtac SAI32 Standard Cylinder SAI32BX25
The AirTAC SAI32X25 is a double-acting ISO 15552 profile cylinder engineered for compact, high-cycle automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit utilizes a short 25 mm stroke ideal for tight clamping jaws and precise ejection tasks. 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 washdown or mildly chemical environments. Fluid ports are PT tapered threads, and because no magnet is specified, it ships without sensor tracks activated. For applications requiring end-of-stroke deceleration, the integrated adjustable air cushions at both ends absorb impact energy effectively.

Where the Airtac SAI32 Standard Cylinder SAI32BX25 Is Used
Short-Stroke Clamping
Ideal for securing small electronic components or thin sheet metal during machining, utilizing the 25 mm stroke to rapidly actuate clamping jaws in confined spaces.
Package Ejection
Provides rapid, repetitive pushing force on conveyor lines to divert lightweight cartons, relying on the 402 N output to reliably knock items off the belt.
Valve Actuation
Serves as a compact actuator for opening and closing small process valves or diverters, where the SUS304 rod offers reliable performance in humid plant environments.
Is the Airtac SAI32 Standard Cylinder SAI32BX25 the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa. If your payload demands less energy, stepping down is not an option as 32 mm is the smallest SAI size, but stepping up to the 40 mm bore yields 628 N if you need a higher safety margin. The 25 mm stroke is optimal for extremely short movements where a guided cylinder might be physically too large.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; the rod will drift. If your fixture requires positive holding without constant air pressure, consider the SAIL variant with an air-released lock or an external pilot-operated check valve. This model serves as a direct, dimensionally interchangeable direct replacement for any ISO 15552 cylinder with a 32 mm bore, 25 mm stroke, PT ports, and standard mounting accessories like LB foot or FA flange.
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 SAI32BX25 FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. If pressure is increased to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X25 is a true ISO 15552 profile cylinder. Its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke, allowing for a direct replacement without modifying your machine plate.
