The AirTAC SAI40 Standard Air Cylinder SAI40BX195 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 195mm 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 SAI40X195 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 195 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable throughput.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel features dual sensor grooves, allowing for straightforward position tracking when paired with compatible reed or solid-state switches.

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 stable 879 N clamping force at 0.7 MPa for securing mid-sized metal or plastic parts during secondary machining operations.
Actuates diverting arms or routing gates on packaging lines, utilizing the 195 mm stroke to push products cleanly between parallel conveyors.
Serves as an ejection cylinder on small injection molding machines, reliably pushing finished parts out of the mold area.
Select this 40 mm bore when an application demands more power than the 32 mm variant (which provides 402 N at 0.5 MPa) but lacks the physical space for a 50 mm unit. Because the 195 mm stroke approaches the threshold where side loading becomes a concern, ensure the load is guided externally to prevent rod-bearing wear.
This model uses a G1/4 port and supports standard ISO 15552 mounting accessories like FA flanges or TC trunnions. If the machinery requires the piston to maintain its position during a complete loss of air pressure, the standard air cushions will not hold the load; consider the SAIL locking variant instead.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. When pressure is increased to 0.7 MPa, the push force rises to 879 N.
Yes, the SAI40X195 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing foot, flange, or trunnion mounts designed for equivalent ISO 15552 profile cylinders.
