The AirTAC AirTAC SAI200X325 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 325mm 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 SAI200X325 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Utilizing an extruded aluminum barrel without tie-rods, it provides a standardized mounting interface that is dimensionally interchangeable with other ISO 15552 actuators. At 0.5 MPa operating pressure, this 200 mm bore generates a substantial 15708 N of push force and 15080 N of pull force, making it well-suited for moving massive loads over its 325 mm stroke.
This model features a standard carbon steel piston rod for high tensile strength under extreme loads. The barrel incorporates dual sensor grooves, allowing for direct mounting of CMSE or DMSE switches when a magnet is specified. For environments requiring elevated temperature resistance, the standard TPU seals can be substituted with Viton (H) or NBR (N) options to match specific fluid and thermal demands.

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 robust 15708 N push force required to actuate large mechanical presses and form thick metal components securely.
Drives heavy-duty mating fixtures over a 325 mm stroke, ensuring industrial components are seated accurately under high compression.
Shifts massive automated pallets on high-throughput manufacturing lines, handling the weight with a rigid 200 mm bore profile.
Selecting this 200 mm bore actuator is appropriate when application thrust requirements exceed the 10053 N push force of the adjacent 160 mm variant. The 325 mm stroke falls well within the 1500 mm maximum standard stroke limit for this bore size. Because this stroke length exceeds 300 mm, the unsupported piston rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
Air is both extended and retracted through G3/4 PT tapered ports, and end-of-stroke deceleration is managed by adjustable air cushions rated for 50 mm. Note that a standard SAI cylinder will drift if air pressure is lost; if the machinery requires a fail-safe position hold under load, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock version.
Quick checklist
Operating at 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X325 is a true ISO 15552 profile cylinder, making its mounting dimensions a drop-in replacement for other ISO 15552 standard actuators. You can retain existing FA flanges or TC trunnion brackets without modifying the machine frame.
