The AirTAC SAI32 Standard Cylinder SAI32BX120 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 120mm 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 SAI32X120 is a double-acting ISO 15552 profile cylinder engineered for standardized automation setups. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit with a 120 mm stroke excels in compact assembly machinery.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It features PT tapered port threads and lacks a standard magnet, meaning direct sensor switching via CMSE or DMSE switches is not supported without modification.

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.
Ideal for driving small clamps and positioning lightweight electronic components on high-speed assembly lines.
Provides reliable actuation for sorting diverters and small package routing gates in material handling systems.
Suited for guiding and tensioning fabric threads where the SUS304 rod prevents moisture-induced degradation.
Choose this 32 mm bore when your application requires roughly 400 N of push force at 0.5 MPa. If your project demands less than 345 N of pull force, stepping down is not an option within this bore size, but moving up to a 40 mm bore provides 628 N push force for heavier loads. Because this is a standard 120 mm stroke, side-load stress on the rod bearing remains minimal.
As a genuine ISO 15552 profile cylinder, it serves as a direct replacement for any standard 32 mm bore, 120 mm stroke unit with a PT G1/8 port and standard mounting accessories like LB foot brackets or FA flanges. Remember that standard SAI cylinders drift when air pressure is lost; they cannot hold a load mid-stroke without external check valves or the SAIL locking variant.
Quick checklist
At 0.5 MPa operating pressure, this cylinder provides 402 N of push force and 345 N of pull force. The maximum theoretical force at 1.0 MPa is 82 kgf.
Because this specific configuration does not include a magnet (-S), it cannot operate with standard CMSE or DMSE reed switches. You must select a -S variant for sensor groove compatibility.
