The AirTAC AirTAC SAI200X225-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 225mm 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 SAI200X225-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N at 0.5 MPa. Its 225 mm stroke is well-suited for large-scale press and lift operations requiring significant linear displacement. The extruded aluminum barrel design omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability per ISO 15552.
This variant includes a built-in magnet for proximity sensing and uses a standard carbon steel piston rod. It features PT tapered port threading and accepts TPU seals for standard operations, with Viton (H) or NBR (N) options available for specialized environmental demands. The dual-side sensor grooves allow seamless installation of CMSE or DMSE switches to track piston position.

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 force needed to form and stamp thick metal sheets in automotive and structural fabrication lines.
Acts as the primary actuator in large pneumatic presses, driving high-tonnage tooling for industrial assembly tasks.
Raises and lowers heavy industrial gates or chutes, utilizing the 225 mm stroke to clear large material flows.
This 200 mm bore size provides the maximum standard thrust in the SAI family, so stepping down to a 160 mm bore (10053 N push at 0.5 MPa) is only advisable if your application requires less force and a smaller footprint. Because the 225 mm stroke is under the 300 mm threshold, side-load bending is less critical here than with longer strokes, but external guides should still be used if the load is offset.
If your machinery experiences a loss of air pressure, this cylinder cannot hold its load in place and will drift. For applications requiring mid-stroke holding or drop prevention, consider the BSAI bidirectional clamp-lock variant or an external rod lock. To match this unit exactly when replacing an ISO 15552 cylinder, ensure the 200 mm bore, 225 mm stroke, G3/4 port, and -S magnet option align with your existing mounting accessories.
Quick checklist
The SAI200X225-S generates a push force of 15708 N at 0.5 MPa, increasing to 21991 N at 0.7 MPa, and reaching a theoretical maximum of 3204 kgf at 1.0 MPa.
Yes, the SAI200X225-S is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders with matching 200mm bore, 225mm stroke, and G3/4 port dimensions.
