The AirTAC Airtac SAI80 Standard Air Cylinder SAI80AX450 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 450mm 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 SAI80X450 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 450mm stroke. It delivers a robust 2513N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning and high-thrust automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that integrates seamlessly into modern machinery.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A), offering excellent corrosion resistance and durability in humid or mildly corrosive environments. It utilizes PT tapered port threads (G3/8) for secure pneumatic connections. Because this unit lacks the -S magnet option, it does not have integrated sensor grooves for reed switches; position sensing must be handled externally if required.

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.
Uses the 2513N push force at 0.5 MPa to eject dense metal parts or heavy molded products from press beds and machining centers.
Extends 450mm to push heavy industrial pallets onto secondary transfer lines or lift stations in automated distribution hubs.
Applies consistent clamping pressure for assembling bearings, bushings, or heavy mechanical components in automated fabrication cells.
Selecting this 80mm bore model makes sense when the 63mm variant's 1559N push force at 0.5 MPa is insufficient for your load, but you want to avoid the larger footprint of the 100mm cylinder. The 450mm stroke provides substantial travel distance for extending actuators, pushing heavy pallets, or lifting materials. Because the stroke is 450mm, the unsupported rod length is significant; side loads will cause rod-bearing bending and premature seal wear. To manage this, use an external guide rail or a guided cylinder body to absorb radial loads and prevent mechanical binding.
As a standard double-acting cylinder, the SAI80X450 relies on live air pressure to move and hold the piston. The adjustable air cushions at both ends decelerate the piston near stroke limits to prevent impact damage, but they do not lock or hold the load in place. If your application drops or drifts when air pressure is lost or the valve is centered, you must use the SAIL (air-released lock) variant, the BSAI bidirectional clamp-lock, or an external pilot-operated check valve. This profile cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders.
Quick checklist
At an operating pressure of 0.5 MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 3518N.
Yes, the SAI80X450 is a genuine AirTac ISO 15552 profile cylinder. Its standardized mounting interface and dimensions make it a drop-in replacement for other ISO 15552 profile cylinders, ensuring easy upgrades and maintenance.
