The AirTAC Airtac SAI125 Standard Air Cylinder SAI125BX100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø125mm bore and 100mm stroke, G1/2 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 SAI125X100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 6136 N of push force at just 0.5 MPa, it excels in high-thrust operations. The extruded aluminum barrel design omits tie rods, providing a clean, standardized mounting interface that drops directly into ISO 15552 machinery footprints.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and operates at speeds of 30-500 mm/s. For applications requiring multi-position stopping or end-of-stroke confirmation, the broader SAI family includes the SAID double-rod variant.

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 6136 N push force required to form and stamp thick-gauge metal components in automated fabrication lines.
Shifts heavy injection molds and tooling blocks securely between stations with precise 100 mm linear displacement.
Powers robust routing arms to redirect heavy pallets along high-capacity material handling conveyors.
Select this 125 mm bore when 80 mm (2513 N at 0.5 MPa) lacks the necessary muscle for heavy lifting, but before stepping up to the massive 160 mm class. The 100 mm stroke provides compact, high-impact clamping. If your machinery experiences pressure loss, this standard cylinder will drift and drop its load; for fail-safe holding, integrate the SAIL pneumatic lock or BSAI clamp-lock variant instead.
As a genuine ISO 15552 cylinder, it ensures dimensional interchangeability with other standard profile cylinders. When replacing, verify the 125 mm bore, 100 mm stroke, PT G1/2 port, and required mounting accessories like CA clevis or TC trunnion brackets.
Quick checklist
At a 0.5 MPa operating pressure, this 125 mm bore cylinder generates 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
Yes, the SAI125X100 is a true ISO 15552 profile cylinder, making its mounting dimensions interchangeable with other ISO 15552 standard cylinders. Confirm your PT port thread and mounting accessory requirements before installation.
