The AirTAC SAI40 Standard Air Cylinder SAI40AX90S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 90mm 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 SAI40X90-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 90mm stroke. It provides a push force of 628 N at 0.5 MPa, making it well-suited for mid-range industrial handling tasks. The extruded aluminum barrel design omits tie-rods for a clean exterior.
This specific configuration includes an -S magnet for use with CMSE and DMSE sensor switches, which mount directly into the dual side grooves. The piston rod is constructed from SUS420J2 stainless steel (option A) for enhanced corrosion resistance, and the fluid port utilizes a PT tapered G1/4 thread.

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 the precise 628 N force and 90mm travel needed to push cartons smoothly across sorting conveyor belts.
Secures workpieces during light machining or assembly, using the SUS420J2 stainless rod to resist workshop moisture.
Handles small to medium payloads in automated lines, pairing the internal magnet with DMSE sensors for position verification.
If your application requires less force, stepping down to the 32mm bore yields 402 N of push force at 0.5 MPa. Conversely, moving up to the 50mm bore provides 982 N. Because this 90mm stroke is relatively short, side-load stress on the rod bearing is minimal, but always ensure axial load alignment.
Being a true ISO 15552 profile cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders. To hold a load safely without continuous air pressure, integrate the SAIL locking variant or an external pilot-operated check valve, as the adjustable air cushions only decelerate the piston near stroke end.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI40X90-S generates a push force of 628 N and a pull force of 528 N. At 0.7 MPa, the push force increases to 879 N.
Yes, as a genuine ISO 15552 profile cylinder, its mounting interface and dimensions are interchangeable with other ISO 15552 compliant cylinders, making it a direct replacement.
