The AirTAC AirTAC SAI200X375-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 375mm 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 SAI200X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built to move massive loads across its 375 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual barrel grooves. Fluid ports feature PT tapered threading, and the piston operates at a controlled speed range of 30-500 mm/s with adjustable air cushions at both ends to absorb end-of-stroke impact.

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 required to actuate large press dies and heavy stamping assemblies at 0.5 MPa operating pressure.
Drives robust diverter gates and heavy-duty sorting flaps on primary aggregate or mining conveyor lines handling dense materials.
Applies consistent clamping pressure for mating oversized industrial components, utilizing its 375 mm stroke to accommodate varying part sizes.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N push force (at 0.5 MPa) of the 160 mm bore variant. If the 15708 N output at 0.5 MPa exceeds your actual load requirements, stepping down to the 160 mm option reduces physical size and air consumption. Because this model features a 375 mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing external guide rails or a dedicated guided cylinder framework is strongly recommended to prevent premature rod-bearing wear.
This unit provides true ISO 15552 dimensional interchangeability, allowing direct replacement of equivalent 200 mm bore, 375 mm stroke profile cylinders. Ensure your setup matches the PT G3/4 port size, accommodates the appropriate mounting accessory (such as TC trunnion or LB foot brackets), and utilizes the -S magnet for position sensing. Note that standard air cushions only decelerate the piston and do not function as a locking mechanism; if pneumatic pressure is lost, the load will drift unless an external pilot check valve is installed.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. If operated at 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X375-S is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounts matching the 200 mm bore and 375 mm stroke, provided the G3/4 PT ports and accessory interfaces align.
