About the Airtac SAI32 Standard Cylinder SAI32BX125S
The AirTAC SAI32X125-S is a double-acting ISO 15552 profile cylinder engineered for direct interchangeability with standardized mounting interfaces. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit is well-suited for compact automation tasks requiring a 125 mm stroke. The extruded aluminum barrel design omits tie-rods for a clean exterior.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance in humid or washdown environments. Equipped with a magnet (-S), it supports direct mounting of CMSE or DMSE sensor switches in the dual side grooves. Fluid compatibility is limited to filtered air, operating reliably between -20 and +70 C.

Where the Airtac SAI32 Standard Cylinder SAI32BX125S Is Used
Small Parts Clamping
Ideal for securing lightweight plastic or aluminum components during machining, utilizing the 402 N push force at 0.5 MPa without deforming the workpiece.
Package Diverting
The 125 mm stroke provides the precise extension needed to push small cartons off a conveyor belt, while the SUS304 rod withstands occasional moisture exposure.
Sensor Actuation
With the integrated magnet (-S), this cylinder easily pairs with DMSE reed switches to trigger downstream pneumatic logic gates upon reaching full extension.
Is the Airtac SAI32 Standard Cylinder SAI32BX125S the Right Cylinder?
Choose this 32 mm bore when an application requires roughly 400 N of push force at 0.5 MPa. If your assembly needs less force, stepping down is not an option within the SAI range, but stepping up to the 40 mm bore yields 628 N. For this 125 mm stroke, side loading is minimal, but always ensure rigid mounting using FA flanges or LB foot brackets. The PT tapered port threads match common pneumatic fittings.
Because this is a standard double-acting cylinder, it will drift and drop its load if air pressure is lost or the control valve is centered. Do not rely on the adjustable air cushions at stroke ends to hold position. If your fixture requires static holding without live pressure, integrate an external pilot-operated check valve or select the SAIL variant with an air-released lock.
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 SAI32BX125S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 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 SAI32X125-S is dimensionally interchangeable per ISO 15552. You can swap it directly into existing ISO 15552 mounting footprints using the same FA, FB, or LB accessories without altering the machine frame.
