The AirTAC SAI63 Standard Cylinder SAI63X140 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 140mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI63X140 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 140mm stroke. It generates 1559N of push thrust and 1402N of pull thrust at 0.5 MPa, making it well-suited for medium-duty industrial handling. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position feedback.
This configuration utilizes a standard carbon steel piston rod and PT (tapered) G3/8 ports. If your assembly requires high-temperature resistance beyond the standard -20 to +70 C range, TPU seals can be swapped out for Viton (H) alternatives to maintain reliability in harsh environments.

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.
Delivers 1559N of push force at 0.5 MPa to securely hold medium-weight machined components during cutting or drilling operations.
Utilizes the 140mm stroke to extend diverter arms smoothly across secondary packaging lines, with adjustable cushions absorbing end-of-stroke impact.
Raises and lowers lightweight access gates on automated machinery, relying on double-acting air power for consistent bidirectional control.
Select this 63mm bore when a 50mm bore falls short—yielding only 982N push force at 0.5 MPa—yet an 80mm bore (2513N push at 0.5 MPa) would be physically oversized or too heavy for your fixture. The 140mm stroke provides adequate travel for clamping and lifting without the side-load risks associated with long extensions. For applications needing secure load holding during air loss, integrate the SAIL variant or an external rod lock, as standard air cushions only decelerate the piston near stroke end.
This unit is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 profile cylinders. It uses a G3/8 PT port, an M16x1.5 rod thread, and 36mm adjustable cushions at both ends. Mounting accessories include FA/FB flanges or TC trunnions, and a magnet (-S) is required if using CMSE or DMSE sensors.
Quick checklist
At 0.5 MPa, the SAI63X140 provides 1559N of push force and 1402N of pull force. If operated at 0.7 MPa, the push force increases to 2182N.
Yes, the SAI63X140 is an ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard ISO 15552 cylinders of the same bore size.
