The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X190 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 190mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI40X190 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Featuring a 40 mm bore and a 190 mm stroke, this tie-rod-less extruded aluminum barrel design provides a standardized mounting interface for seamless integration.
This configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external switches; adding the -S option enables CMSE or DMSE sensors via the dual side 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.
Provides reliable 628 N holding force at 0.5 MPa for securing medium-sized workpieces during machining or assembly operations.
Extends 190 mm to push products between parallel conveyor lanes with smooth, adjustable air cushioning at both ends.
Ideal for knocking finished parts out of molds or press dies, utilizing 879 N of push force at 0.7 MPa to overcome ejection resistance.
Choose this 40 mm bore when an application requires more thrust than the 32 mm variant (which provides 402 N at 0.5 MPa) but has spatial constraints that prohibit the larger 50 mm option (982 N at 0.5 MPa). For this 190 mm stroke, side loads are moderate, but ensure proper rod-bearing alignment to prevent premature wear.
As a true ISO 15552 cylinder, it serves as a drop-in replacement matching the 40 mm bore, 190 mm stroke, G1/4 port, and standard mounting accessories like FA flange or LB foot brackets. Note that standard air cushions only decelerate the piston at end-of-stroke; if your process requires the load to be held mechanically without air pressure, select the SAIL lock variant instead.
Quick checklist
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. When operating at 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X190 is dimensionally interchangeable per ISO 15552. You can drop it in to replace other standard 40 mm bore profile cylinders with a 190 mm stroke and G1/4 porting.
