The AirTAC SAI32 Standard Cylinder SAI32BX45 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 45mm 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 SAI32X45 is a double-acting ISO 15552 profile cylinder engineered for compact, space-constrained automation. Delivering a push force of 402 N at 0.5 MPa, this 32 mm bore unit with a 45 mm stroke excels in short-travel positioning tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This specific configuration features a SUS304 stainless steel piston rod (material code B), providing superior corrosion resistance for humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, focusing purely on mechanical actuation without sensor tracking requirements.

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 rapid 45 mm retraction to push lightweight plastic or metal components out of a machining center using 402 N of force.
Actuates a short-stroke diverter arm to route small cardboard cartons on a high-speed packaging conveyor line.
Drives a secondary clamping jaw in tight fixture assemblies where a 32 mm bore provides adequate holding without excess bulk.
Select this 45 mm stroke variant when your application requires precise short-travel movement without the spatial overhead of longer cylinders. If your mechanism needs slightly higher thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa, but increases the physical footprint.
Because this model lacks a magnet, position sensing requires external limit switches. If air pressure drops, the piston will drift and cannot hold a load; for suspended loads requiring fail-safe holding, consider the SAIL variant with an air-released lock. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders, matching the 32 mm bore, 45 mm stroke, PT port, and standard mounting accessories like LB foot or FA flange.
Quick checklist
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X45 is a true ISO 15552 profile cylinder, making its mounting dimensions interchangeable with other ISO 15552 cylinders. You can swap it directly using the existing 32 mm bore mounting hardware and PT port connections.
