The AirTAC AirTAC SAI200X105 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 105mm 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 SAI200X105 is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It delivers a robust push force of 15708 N at 0.5 MPa, making it ideal for high-mass displacement tasks. The 105 mm stroke provides targeted linear movement for substantial loads. Engineered with a PT tapered port thread and a SUS304 stainless steel rod, this variant offers superior corrosion resistance for harsh environments.
This extruded aluminum barrel design omits tie-rods and features sensor grooves on both sides. While standard models lack a magnet for proximity switches, the cylinder accommodates high-temperature Viton (H) seals if your thermal environment demands it. For operations requiring multi-directional clamping, the related BSAI bidirectional clamp-lock series offers an alternative solution.

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 immense 15708 N thrust needed to seat large bearings or stamp heavy gauge metal components securely.
Drives large robotic clamping arms that hold chassis frames stationary during high-torque welding operations.
Actuates massive mold separation plates and ejects heavy finished plastic parts from industrial injection molds.
Selecting this 200 mm bore cylinder is appropriate when the 160 mm bore (delivering 10053 N at 0.5 MPa) cannot provide enough thrust for your heavy machinery. Because the SAI200X105 uses a PT tapered thread, ensure your fittings match this standard to prevent air leaks. The 105 mm stroke is safely below the 1500 mm maximum, so rod-bearing bending is not a concern here.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders. Note that a plain SAI does not secure a load if air pressure drops; the piston will drift. If your application requires true position holding without continuous pressure, integrate an external pilot-operated check valve or specify the SAIL lock variant.
Quick checklist
The SAI200X105 generates a push force of 15708 N at 0.5 MPa, and up to 21991 N at 0.7 MPa, utilizing its 200 mm bore.
Yes, the SAI200X105 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders.
