The AirTAC AirTAC SAI200X275 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 275mm 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 SAI200X275 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at just 0.5 MPa, this 200 mm bore unit is built to move massive loads over its 275 mm stroke. The extruded aluminum barrel design omits traditional tie-rods, providing a sleek profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Configured here with a SUS304 stainless steel piston rod (material code B), it offers superior corrosion resistance for harsh or washdown environments. This specific build utilizes PT tapered port threads and lacks a standard magnet. For applications requiring intermediate stopping or end-locking under pressure loss, the SAIL or BSAI clamp-lock variants should be specified instead.

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 15708 N push force at 0.5 MPa required for pressing, stamping, and forming thick metal components in automated fabrication lines.
Shifts heavy injection molds or industrial tooling securely over a 275 mm stroke, leveraging the robust 200 mm bore for high thrust capacity.
Actuates rugged gates or heavy diverter mechanisms in mining and aggregate machinery, benefiting from the SUS304 rod's resistance to harsh particulate environments.
Selecting this 200 mm bore is appropriate when the 160 mm class (10053 N at 0.5 MPa) is insufficient for your kinetic requirements. Operating speeds for this large bore range from 30-500 mm/s. Because the 275 mm stroke is relatively short for this massive bore, rod-bearing bending is less of a concern here, but external guide rails should still be evaluated for any significant side loads to prevent premature seal wear.
As a true ISO 15552 cylinder, this model serves as a direct dimensional drop-in replacement. When ordering, confirm your mounting accessories (such as LB foot or TC trunnion), ensure your PT port fittings match the G3/4 interface, and note that position sensing is not possible on this unit without the -S magnet option. If the machinery cannot tolerate drifting upon air exhaustion, an external pilot-operated check valve is required.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 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 SAI200X275 is dimensionally interchangeable per ISO 15552 standards. It shares the same mounting interface and G3/4 port locations as other standard profile cylinders, making it a direct drop-in replacement.
