The AirTAC Airtac SAI80 Standard Air Cylinder SAI80X630S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 630mm 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 SAI80X630-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It generates 2513 N of push force at 0.5 MPa and utilizes a 630 mm stroke to cycle large mechanisms. The extruded aluminum barrel omits tie rods, providing a smooth exterior that simplifies cleaning and sensor mounting.
Equipped with a magnetic piston (-S), this unit directly supports CMSE and DMSE reed switches via the integrated dual-side sensor grooves. The standard carbon steel piston rod offers high tensile strength for demanding industrial environments, while adjustable air cushions at both ends absorb end-of-stroke kinetic energy.

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 the 2513 N push force required to index heavy pallets or push large metal blanks along a conveyor line over a 630 mm distance.
Applies steady clamping pressure for light-duty pressing, bending, or holding large composite panels during secondary machining operations.
Actuates heavy vertical lifting doors or safety gates, utilizing the 630 mm stroke while relying on the adjustable cushions to soften the top stop.
Selecting this 80 mm bore is ideal when a 63 mm bore (1402 N pull at 0.5 MPa) lacks the necessary thrust, but a 100 mm bore is physically too large. For a 630 mm stroke, the extended rod is highly susceptible to bending under side loads. Implement an external guide rail or use a guided cylinder to prevent premature rod-bearing wear and seal failure.
This model uses a G3/8 PT tapered port and includes a magnet for position sensing. If the machinery loses air pressure, the piston will drift and cannot hold a vertical load; integrate an external pilot-operated check valve or specify a SAIL lock variant for fail-safe holding. Being dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X630-S is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with an 80 mm bore and 630 mm stroke, matching the G3/8 port and mounting dimensions.
