The AirTAC AirTAC SAI200X135-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 135mm 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 SAI200X135-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N push force at 0.5 MPa, this 200 mm bore unit handles massive payloads with ease. The 135 mm stroke provides substantial extension for large-scale pressing, lifting, and clamping operations.
Equipped with a magnetic piston for position sensing, it supports CMSE and DMSE switches via sensor grooves on both sides of the extruded aluminum barrel. The rod is constructed from standard carbon steel, while the PT tapered port threads ensure a secure, leak-free pneumatic connection in demanding industrial environments.

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.
Generates up to 21991 N of push force at 0.7 MPa for forming, stamping, and assembling large metal components.
Provides the massive linear thrust needed to actuate heavy platens and tooling in large-scale automated manufacturing lines.
Ideal for elevating heavy pallets or machinery components, utilizing the magnetic piston for precise end-of-stroke confirmation.
Select this 200 mm bore cylinder when applications exceed the 10053 N push force of the 160 mm variant at 0.5 MPa. For lower force requirements, stepping down to the 160 mm bore optimizes space and air consumption. Because the stroke is 135 mm, side-load risks are moderate, but ensuring proper rod-bearing alignment remains critical for longevity.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders. To match this exact configuration, specify a 200 mm bore, 135 mm stroke, PT port thread, and the -S magnet option. Note that standard SAI cylinders do not hold loads without constant air pressure; use the SAIL lock variant if fail-safe holding is required.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X135-S is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders, allowing it to serve as a drop-in replacement using standard mounting accessories.
