The AirTAC Airtac SAI63 Standard Cylinder SAI63BX35S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 35mm 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 SAI63X35-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke actuation. Delivering a push force of 1559 N at 0.5 MPa, it excels in compact positioning tasks. The extruded aluminum barrel omits tie rods, presenting a clean exterior that resists impact in tight machinery layouts.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance. Equipped with a -S magnet, it directly supports CMSE and DMSE sensor switches via the dual side grooves. Fluid connections use PT tapered threads, ensuring a robust, leak-free pneumatic seal.

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 1559 N of holding force to secure steel plates during machining operations.
Executes rapid 35 mm strokes to push products off a high-speed sorting line.
Reliably opens and closes small pneumatic process gates in washdown environments.
Choosing this 63 mm bore over the smaller 50 mm variant upgrades your thrust from 982 N to 1559 N at 0.5 MPa, which is critical if overcoming higher friction. Conversely, if your load requires less energy, stepping down reduces air consumption. The 35 mm stroke keeps the rod unsupported length minimal, mitigating side-load bending risks.
Because this is a double-acting cylinder, it cannot hold a load if air pressure drops; use the SAIL variant for pneumatic locking needs. To match an existing ISO 15552 footprint, verify the 63 mm bore, 35 mm stroke, G3/8 PT port, and required mounting accessory before requesting a quote.
Quick checklist
At 0.5 MPa operating pressure, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, it is built to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders. Always confirm your port size and mounting dimensions match.
