The AirTAC SAI32 Standard Cylinder SAI32BX115S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 115mm 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 SAI32X115-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. It delivers a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, making this 115 mm stroke variant well-suited for mid-length positioning tasks in tight machinery.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnetic piston (-S) for direct compatibility with CMSE and DMSE sensor switches. The extruded aluminum barrel incorporates sensor grooves on both sides, while fluid connections utilize PT tapered threads.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides reliable push force to eject small machined parts from a fixture using the 115 mm stroke reach.
Actuates a lightweight diverter arm on a packaging line, utilizing the magnetic piston for position confirmation.
Extends and retracts a secure latch pin on automated storage drawers, benefiting from the SUS304 rod in humid environments.
Select this 32 mm bore when an application requires roughly 400 N of push force at 0.5 MPa. If your fixture demands less energy, stepping down is an option, but moving up to a 40 mm bore increases the push force to 628 N at 0.5 MPa. Because the 115 mm stroke is under 300 mm, rod-bearing bending is minimal, though external guides remain recommended for heavy off-center loads.
This unit provides direct dimensional interchangeability with other ISO 15552 cylinders. To match this exact replacement, specify a 32 mm bore, 115 mm stroke, PT G1/8 port, and the -S magnet option. Note that a standard SAI relies entirely on continuous air pressure to maintain its position; if pneumatic supply is lost, the piston will drift. For dead-load holding, consider the SAIL locking variant.
Quick checklist
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder generates a push force of 563 N and a pull force of 483 N. At 0.5 MPa, the push force is 402 N.
Yes, the SAI32X115-S is dimensionally interchangeable per ISO 15552. It shares the same mounting interface and G1/8 port size as other standard 32 mm profile cylinders, allowing for direct replacement.
