The AirTAC AirTAC SAI200X125 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 125mm stroke, G3/4 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 SAI200X125 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic actuation. Operating at 0.5 MPa, it generates 15708 N of push force and 15080 N of pull force, making it ideal for moving substantial loads across a 125 mm stroke. Its extruded aluminum barrel omits tie rods, presenting a clean exterior that integrates seamlessly into high-tonnage machinery.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. Fluid supply connects via PT tapered ports. While adjustable air cushions at both ends decelerate the piston to minimize impact, note that this standard variant does not include a magnet for proximity sensing.

Drives large metal forming and stamping presses requiring up to 15708 N of thrust at 0.5 MPa.
Actuates heavy mold cores and ejector mechanisms in large injection molding equipment.
Swings heavy-duty diverter arms on mining or aggregate conveyors handling dense bulk materials.
Selecting this 200 mm bore is appropriate when 160 mm (10053 N push at 0.5 MPa) cannot drive your load, providing a significant leap to 15708 N. Because the 125 mm stroke is below the 300 mm threshold, rod-bearing bending stress from side loads is less pronounced than on longer units, though external guiding remains best practice for heavy lateral masses. As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders, matching the G3/4 porting and standard mounting accessories like the CA clevis or TC trunnion. If the machinery must secure the load mechanically during air pressure loss, step up to the SAIL or BSAI variants rather than relying on this base cylinder.
Quick checklist
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X125 is dimensionally interchangeable per ISO 15552. It matches standard mounting footprints and G3/4 port sizes, serving as a direct drop-in replacement.
