The AirTAC SAI32 Standard Cylinder SAI32BX375 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 375mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X375 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 563 N at 0.7 MPa. Its 375 mm stroke makes it well-suited for intermediate linear positioning tasks that require a compact footprint. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies the mounting of accessories.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and does not include a magnet. For applications requiring position holding without continuous air pressure, consider the SAIL locking variant.

Extends 375 mm to push small totes or cartons off a main conveyor line into a secondary packing lane using 563 N of force at 0.7 MPa.
Ejects machined plastic parts from a mold cavity, utilizing the SUS304 stainless steel rod to withstand occasional coolant splashes.
Powers a pivoting sorting gate that routes small parcels, requiring a compact 32 mm bore profile to fit within tight conveyor framework.
Selecting this 32 mm bore cylinder makes sense when your application requires roughly 402 N of push force at 0.5 MPa. If your load demands less energy, stepping down is difficult as this is the smallest standard SAI bore; however, stepping up to a 40 mm bore increases the 0.5 MPa push force to 628 N.
Because the 375 mm stroke is relatively long for a 32 mm bore, the unsupported rod is susceptible to bending under side loads. Implement an external guide rail or use a guided cylinder to prevent premature rod-bearing wear. As a standard double-acting actuator, this model will drift if air pressure is lost. To match this cylinder for an ISO 15552 direct replacement, ensure the 375 mm stroke, PT G1/8 ports, and desired mounting accessory (such as an LB foot or FA flange) align with your existing fixture.
Quick checklist
At an 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 you increase the pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X375 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounts matching the 32 mm bore and 375 mm stroke, provided your setup accommodates the G1/8 PT port threads.
