The AirTAC Airtac SAI80 Standard Air Cylinder SAI80X550 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 550mm stroke, G3/8 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 SAI80X550 is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It delivers a robust 2513N push force at 0.5 MPa, making it well-suited for demanding material handling tasks. The 550mm stroke provides ample travel for automated clamping and lifting stations.
This model features a standard carbon steel piston rod for high tensile strength and durability. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for flexible mounting of CMSE or DMSE position switches when a magnet is specified. Adjustable air cushions at both ends ensure smooth deceleration of large moving masses.

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.
Generates 3518N of thrust at 0.7 MPa, ideal for assembling bearings and pressing heavy components into housings.
The 550mm stroke provides the extended reach needed to push large pallets or workpieces off high-throughput conveyor lines.
Lifts substantial vertical loads in automated storage systems, utilizing adjustable cushions to protect payloads at stroke end.
Select this 80mm bore cylinder when 50mm bore models (providing 982N at 0.5 MPa) lack the necessary thrust for your heavy fixtures. If your application requires even higher force, stepping up to a 100mm bore yields 3927N at 0.5 MPa. Because this unit features a 550mm stroke, external guides are highly recommended to prevent rod-bearing bending under side loads; a guided cylinder configuration will maximize service life.
For replacement parts, verify the 80mm bore, 550mm stroke, PT G3/8 port thread, and your required mounting accessory (such as LB foot or TC trunnion). Note that this standard SAI does not hold loads safely upon air loss; for fail-safe holding, integrate an external rod lock or specify the SAIL (air-released lock) variant.
Quick checklist
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the standard 0.7 MPa operating pressure, the push force increases to 3518N.
Yes, the SAI80X550 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 80mm bore, 550mm stroke, and G3/8 port.
