The AirTAC AirTAC SAI200X850-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 850mm 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 SAI200X850-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore unit is built to move massive loads across its 850 mm stroke. The extruded aluminum barrel omits traditional tie-rods, providing a sleek profile while maintaining strict dimensional interchangeability per ISO 15552 standards.
Configured with a SUS304 stainless steel rod for superior corrosion resistance, this model includes a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches seated in the dual barrel grooves. Fluid connections use PT tapered ports, and the standard TPU seals accommodate operating pressures from 0.15-1.0 MPa.

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 force at 0.5 MPa required to actuate large mechanical stamping presses and heavy forming dies.
Drives heavy structural components into alignment pins during automated automotive chassis welding fixtures.
Exerts high lateral thrust to shift fully loaded industrial pallets onto secondary processing conveyor lines.
Selecting this 200 bore cylinder is appropriate when 160 mm bore hardware (providing 10053 N at 0.5 MPa) lacks the necessary thrust for high-inertia loads. Because the 850 mm stroke exceeds the 300 mm threshold, the unsupported rod is highly susceptible to bending under side loads. Implement an external guide rail or utilize a guided cylinder carriage to prevent premature rod-bearing wear.
This model serves as a drop-in replacement for any ISO 15552 cylinder matching the 200 mm bore, 850 mm stroke, G3/4 port, and standard mounting accessory dimensions. If the machinery must retain a load safely during a loss of air pressure, a standard SAI will drift; specify the BSAI clamp-lock variant or install an external pilot-operated check valve.
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. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder will drop if air pressure is lost. The adjustable air cushions only decelerate the piston at stroke end. For fail-safe load holding, use the BSAI clamp-lock variant or an external rod lock.
