The AirTAC AirTAC SAI200X850-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 850mm 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 SAI200X850-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200mm bore unit is built to move massive loads. The 850mm stroke provides extensive travel for large-scale material handling. Because it uses an extruded aluminum profile barrel, it avoids tie-rod exposure while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a magnet (-S) for direct mounting of CMSE or DMSE sensor switches along the dual side grooves. It is equipped with a SUS420J2 stainless steel piston rod (material code A) for enhanced durability against moisture and minor corrosion. The pneumatic supply connects via PT tapered thread ports sized at G3/4, and adjustable air cushions at both ends absorb end-of-stroke kinetic energy.

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 massive 15708 N push force required to actuate large forming presses and heavy industrial machinery over its 850mm travel.
Ideal for shifting heavy pallets or structural components in automated high-bay warehouses where long stroke and high thrust are mandatory.
Drives large-scale welding and positioning jigs on automotive lines, utilizing its SUS420J2 rod to resist plant environment wear.
Selecting this 200mm bore cylinder is appropriate when the 160mm bore class (providing 10053 N at 0.5 MPa) is insufficient for your dynamic load requirements. At an 850mm stroke, the extended rod is highly susceptible to bending under side loads. You must use an external guide rail or a dedicated guided cylinder to prevent rod-bearing destruction and ensure smooth linear travel.
Be aware that an unmodified SAI cylinder will drift or drop if air pressure is lost or the valve is centered; it cannot hold a load safely without live pressure. If your application demands true fail-safe load holding, specify the SAIL variant with an air-released lock, or use the BSAI bidirectional clamp-lock design. This SAI200X850-S model is a drop-in replacement for any ISO 15552 cylinder matching the 200mm bore, 850mm stroke, G3/4 PT port, and -S magnet specifications.
Quick checklist
This 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force at a 0.5 MPa operating pressure. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X850-S is dimensionally interchangeable per ISO 15552. It can serve as a drop-in replacement for other ISO 15552 profile cylinders with matching 200mm bore, 850mm stroke, and G3/4 port dimensions.
