The AirTAC AirTAC SAI200X85-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 85mm 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 SAI200X85-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation, providing 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa. Its 85 mm stroke is tailored for high-force, short-travel clamping and pressing operations. As a genuine AirTAC component, it guarantees dimensional interchangeability with other ISO 15552 profile cylinders for seamless machine integration.
This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in humid or mildly chemically washed environments. It is equipped with a magnet (-S) to trigger CMSE or DMSE reed sensors, and the extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.

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 the 21991 N at 0.7 MPa needed to form thick-gauge sheet metal and execute short-stroke stamping operations.
Ideal for robust press tasks requiring high impact force over an 85 mm travel distance, such as bearing assembly or pin insertion.
Secures large fabricated structures during welding or machining, utilizing the full 200 mm bore power for zero movement.
At 200 mm bore, this cylinder sits at the top of the standard SAI range, offering a theoretical maximum force of 3204 kgf at 1.0 MPa. If 15708 N at 0.5 MPa is excessive for your application, stepping down to a 160 mm bore yields 10053 N while saving physical footprint and air consumption. The PT tapered port threads ensure a robust, metal-to-metal seal.
Because the 85 mm stroke is relatively short, rod-bearing bending from side loads is minimal, but external guides should still be used to prevent binding. Note that the standard SAI does not hold its position when air pressure is removed; for fail-safe load holding upon pressure loss, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the adjustable air cushions.
Quick checklist
At 0.5 MPa, the push force is 15708 N, increasing to 21991 N at 0.7 MPa, with a theoretical maximum of 3204 kgf at 1.0 MPa.
Yes. The SAI200X85-S is built to ISO 15552 profile cylinder standards, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke.
