The AirTAC AirTAC SAI200X90-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 90mm 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 SAI200X90-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 90 mm stroke is ideal for high-impact, short-travel clamping or pressing tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures a standardized mounting interface for straightforward machinery integration.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. As a -S variant, it features an integrated magnet and dual sensor grooves on the barrel, allowing direct mounting of CMSE or DMSE reed switches for precise end-of-stroke position detection. Fluid ports utilize a PT tapered thread type.

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 robust 15708 N push force required for short-stroke metal forming, riveting, and impact stamping presses.
Ideal for high-tonnage pressing applications where a brief 90 mm travel distance is needed to seat bearings or assemble heavy components.
Secures large, heavy pallets or molds in place during machining or transfer operations, utilizing the integrated magnet for cycle confirmation.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N push force (at 0.5 MPa) of the smaller 160 mm bore variant. Operating speed for this large-bore unit ranges from 30-500 mm/s. For this 90 mm stroke, side-load stress on the rod bearing is minimal, though external guides are recommended if the mechanism experiences heavy off-center loading.
This model functions strictly as a double-acting actuator. The adjustable air cushions at both ends serve only to decelerate the massive piston near the stroke endpoints; they do not lock or hold a load. If your process requires position holding upon loss of air pressure, consider the BSAI bidirectional clamp-lock series or an external pilot-operated check valve. For direct drop-in replacements, match the 200 mm bore, 90 mm stroke, PT G3/4 ports, and appropriate mounting accessories like the TC trunnion.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X90-S is dimensionally interchangeable per ISO 15552. You can drop it into existing setups designed for ISO 15552 profile cylinders by matching the 200 mm bore, 90 mm stroke, and G3/4 port dimensions.
