The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X700 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 700mm 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 SAI40X700 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 700mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for medium-duty positioning tasks. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that speeds up machine cleaning and sensor placement.
This specific configuration utilizes a standard carbon steel piston rod and features PT tapered port threading on the G1/4 connection. Without a built-in magnet, it is optimized for purely mechanical actuation. Adjustable air cushions at both stroke ends absorb kinetic energy, ensuring smooth stops even at the maximum operating speed of 800 mm/s.

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.
Drives long-stroke routing arms on packaging lines to divert cartons between parallel conveyor belts over a 700mm span.
Executes extended reach ejection of machined aluminum parts from an enclosed CNC cell, utilizing the full 700mm stroke.
Actuates lightweight access gates or safety barriers on automated storage retrieval systems requiring 879N push force at 0.7 MPa.
When selecting this actuator, compare its 628N push force at 0.5 MPa against the smaller SAI32 bore (402N push) or the larger SAI50 bore (982N push) to match your load requirements. At a 700mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, pair this cylinder with an external guide rail or utilize a fully guided linear slide.
This unit serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder. To complete your assembly, pair it with FA or FB flange mounts, and note that adding an -S magnet variant is required if you intend to track piston position using DMSE or CMSE switches. If the application demands fail-safe holding without continuous air pressure, explore the SAIL locking variant instead of relying on the cushions.
Quick checklist
At an operating pressure of 0.7 MPa, the SAI40X700 generates 879N of push force and 740N of pull force. At 0.5 MPa, it provides 628N of push force.
Yes, the SAI40X700 is dimensionally interchangeable per ISO 15552 standards. It matches standard mounting footprints and G1/4 port locations, serving as a direct drop-in replacement.
