The AirTAC AirTAC SAI200X475-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 475mm 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 SAI200X475-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 15708 N at 0.5 MPa, this 200mm bore actuator easily manages massive loads across its 475mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a -S magnet, this unit operates seamlessly with CMSE and DMSE sensor switches housed in the dual side grooves. The standard carbon steel piston rod ensures high tensile strength for rigorous cycles, while adjustable air cushions at both ends absorb end-of-stroke impacts. For environments requiring elevated thermal resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives.

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 immense thrust needed for pressing, stamping, and bending thick metal components in primary manufacturing lines.
Drives massive platens and tooling fixtures together during the heavy-duty assembly of automotive frames and industrial machinery.
Actuates large-scale diverters, heavy gates, and positioning stops used in high-capacity logistics and bulk material conveyance.
Selecting this 200mm bore actuator is appropriate when systems require upward of 15000 N of push force at 0.5 MPa; stepping down to a 160mm bore reduces that output to 10053 N. Because this model features a 475mm stroke, the extended carbon steel rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a guided cylinder module to absorb lateral forces.
This unit uses G3/4 PT tapered ports and operates within a 30-500 mm/s speed range. As a standard double-acting cylinder, it will not maintain its position if air pressure is lost or the control valve is centered. If the application demands fail-safe load holding without constant live pressure, integrate the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
Quick checklist
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X475-S is dimensionally interchangeable per ISO 15552. You can drop it directly into existing mounting accessories like FA flanges or TC trunnions, provided the 200mm bore, 475mm stroke, and G3/4 port specifications match your system.
