The AirTAC SAI32 Standard Cylinder SAI32BX550S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 550mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X550-S is a double-acting ISO 15552 profile cylinder engineered for direct compatibility with standardized mounting interfaces. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built to handle a 550 mm non-standard stroke, making it a tailored solution for extended reach applications.
Equipped with a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE or DMSE sensor integration, it operates reliably at speeds from 30 to 800 mm/s. The barrel features dual sensor grooves, and fluid connections use PT tapered threads.

Pushes lightweight jigs or parts across a 550 mm gap with 402 N of force at 0.5 MPa, utilizing the SUS304 rod to resist moisture in washdown areas.
Actuates a diverter arm over a wide conveyor belt, relying on the integrated magnet to trigger DMSE position switches at full extension.
Ejects cartons from a secondary packaging station, where the adjustable air cushions absorb kinetic energy at both ends of the lengthy 550 mm travel.
Because this 550 mm stroke exceeds the 32 mm bore's 500 mm standard limit, it is produced as a non-standard, made-to-order item. When executing such a long extension, the unsupported rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder framework is strongly recommended to prevent rod-bearing damage.
If an application requires holding a load securely without continuous live air pressure, note that the standard adjustable air cushion only decelerates the piston at stroke end and will not act as a brake. For positive locking under pressure loss, specify the SAIL variant or an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, requiring only a matching 32 mm bore, 550 mm stroke, PT port, and appropriate mounting accessory.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
Yes, it shares the exact ISO 15552 profile mounting interface, allowing it to drop into existing 32 mm bore setups. Just ensure your setup accommodates the 550 mm non-standard stroke and PT port connections.
