The AirTAC SAI40 Standard Air Cylinder SAI40AX375S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 375mm 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 SAI40X375-S is a double-acting ISO 15552 profile cylinder engineered for mid-range linear motion tasks. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force, making it well-suited for automated assembly and material handling routines requiring a 375 mm travel distance.
This specific configuration includes an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It is built with a -S magnet, allowing seamless integration with CMSE or DMSE sensor switches mounted directly into the dual-side extruded aluminum barrel grooves.

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.
Actuates diverter arms on packaging lines, utilizing the 375 mm stroke to push cartons smoothly between adjacent conveyor belts.
Presses bearings or pins into housings on automated machining lines, using the 879 N push force available at 0.7 MPa.
Deposits lightweight goods onto multi-tier pallet stacks, where the SUS420J2 rod provides reliable resistance against humid warehouse environments.
Selecting this 40 mm bore is optimal when an application requires more power than a 32 mm bore (which provides 402 N push at 0.5 MPa) but does not need the larger footprint of a 50 mm bore (982 N push at 0.5 MPa). Because the 375 mm stroke creates a lengthy unsupported rod extension, operators must manage potential side-load and rod-bearing bending by incorporating external guide rails or choosing a fully guided cylinder to prevent premature wear.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a direct replacement for other standard profile cylinders sharing the same 40 mm bore, 375 mm stroke, PT G1/4 port, and standard mounting accessories like FA flanges or LB foot brackets. Note that standard air cushions only decelerate the piston at stroke ends; if the pneumatic supply drops, the rod will drift. For position holding without live pressure, specify the SAIL or BSAI locking variant.
Quick checklist
At a standard operating pressure of 0.7 MPa, this 40 mm bore cylinder provides a push force of 879 N and a pull force of 738 N. At 0.5 MPa, the push force is 628 N.
Yes, the SAI40X375-S is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. It uses a PT G1/4 port and supports standard FA, FB, LB, and TC mounting accessories.
