The AirTAC SAI80 Standard Air Cylinder SAI80BX135 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 135mm 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 SAI80X135 is a double-acting ISO 15552 profile cylinder offering a robust 2513N push force at 0.5 MPa. Its 135mm stroke is well-suited for medium-travel material handling and clamping tasks. The extruded aluminum barrel eliminates protruding tie rods, presenting a clean exterior that resists mechanical debris accumulation.
Configured here with a SUS304 stainless steel piston rod (option B), this variant provides excellent corrosion resistance for humid or washdown-adjacent environments. It features PT tapered G3/8 ports and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported on this specific unit.

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 2513N of thrust at 0.5 MPa, ideal for securing heavy metal workpieces during machining or welding operations.
The 135mm stroke offers precise travel for pushing heavy pallets off a main conveyor line onto a secondary packaging branch.
Exerts reliable downward force for light-duty assembly presses, seating bearings or pins with consistent mechanical advantage.
Selecting this 80mm bore makes sense when a 63mm bore (1559N at 0.5 MPa) lacks the necessary thrust for your heavier payloads. If your application requires position holding under pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke ends; a SAIL variant with an air-released lock or a BSAI clamp-lock cylinder is required for true load holding.
For a direct replacement, match the 80mm bore, 135mm stroke, G3/8 PT port, and your required mounting accessory (such as an LB foot or TC trunnion). Because this unit lacks the -S magnet suffix, it cannot host reed switches; if sensing is needed, select an SAI80X135-S instead.
Quick checklist
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. It can reach up to 3518N push at 0.7 MPa.
Yes, the SAI80X135 is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 profile cylinders, matching the standard 80mm mounting interface and G3/8 port size.
