The AirTAC SAI40 Standard Air Cylinder SAI40BX150S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 150mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI40X150-S is a double-acting ISO 15552 profile cylinder offering a theoretical push force of 628 N at 0.5 MPa. Its 150 mm stroke provides the precise linear movement required for medium-duty handling and clamping tasks. This variant includes a standard magnet for position sensing.
Built to exacting dimensional standards, this model is a direct replacement for other ISO 15552 cylinders. It features a SUS304 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads. Adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

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 628 N clamping force at 0.5 MPa for securing workpieces during automated machining or assembly processes.
The 150 mm stroke actuates diverter arms and sorting gates smoothly on packaging lines, utilizing adjustable end cushions to prevent impact damage.
Ideal for lifting and pushing medium-weight goods in automated storage and retrieval systems where SUS304 rod durability is advantageous.
Select this 40 mm bore when a 32 mm bore (402 N push at 0.5 MPa) is insufficient, but a 50 mm bore (982 N push at 0.5 MPa) would be excessive and waste air consumption. The 150 mm stroke is well within the 1200 mm maximum standard stroke limit for this bore size, making it highly versatile. If your application requires the load to remain held without continuous air pressure, a standard SAI will drift; you should specify the SAIL lock variant or use an external pilot-operated check valve.
This configuration uses PT tapered ports, a G1/4 thread size, and an M12x1.25 rod thread. The integrated magnet (-S) enables direct mounting of CMSE or DMSE series sensor switches in the dual side grooves of the extruded aluminum barrel. Operating speed ranges from 30-800 mm/s.
Quick checklist
The SAI40X150-S generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X150-S is dimensionally interchangeable with other standard ISO 15552 profile cylinders. It shares the same mounting interface and accessories, though it features PT tapered ports and a SUS304 rod.
