The AirTAC AirTAC SAI200X145-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 145mm 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 SAI200X145-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 200mm bore unit is built to move substantial masses. The 145mm stroke provides targeted actuation for high-force clamping or pressing tasks. The extruded aluminum barrel design eliminates traditional tie-rods, offering a clean exterior that integrates seamlessly into modern machinery.
This specific configuration includes a magnet for proximity sensing (-S), allowing direct mounting of CMSE or DMSE switches along the dual sensor grooves. It features a standard carbon steel piston rod and PT (tapered) port threads. For applications requiring exceptional heat resistance, the standard TPU seals can be swapped for Viton (H) alternatives to handle higher operating temperatures.

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 intense 15708 N push force required to form thick metal components in automated stamping presses.
Delivers reliable high-force ejection of large molded plastic parts, utilizing the -S magnet to confirm ejection completion.
Acts as the primary actuator in large-scale bending equipment, where its 200mm bore handles immense material resistance.
Selecting this 200mm bore cylinder is ideal when 15708 N of push force at 0.5 MPa is required, stepping up significantly from the 160mm bore which yields 10053 N. If full force is not necessary, dropping to the 160mm bore saves space and air consumption. The 145mm stroke is a custom non-standard length, made-to-order to fit specific machinery envelopes where standard 125mm or 150mm strokes are unsuitable.
Because the stroke is under 300mm, rod-bearing bending stress is minimal, but heavy radial loads should still be guided externally. This cylinder relies on live air pressure to maintain its position; if pressure is lost, the piston will drift. For dead-drop prevention, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. It serves as a dimensionally interchangeable drop-in replacement per ISO 15552 mounting interfaces, utilizing a G3/4 port.
Quick checklist
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X145-S is dimensionally interchangeable per ISO 15552 mounting dimensions. You can drop it into existing ISO 15552 foot, flange, or trunnion setups without modifying the machine frame.
