The AirTAC AirTAC SAI200X650-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 650mm 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 SAI200X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N of push force at 0.5 MPa, this 200mm bore unit is built to drive substantial masses across its 650mm stroke. The extruded aluminum barrel design omits tie rods to provide a smooth, standardized mounting interface that drops directly into existing ISO 15552 machinery layouts.
This specific configuration includes a magnet for proximity sensing via CMSE or DMSE switches mounted into the dual sensor grooves. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced resistance against corrosion and surface wear. It utilizes PT tapered port threads and features adjustable air cushions at both ends to absorb impact energy at the stroke limits.

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 heavy stamping dies and form thick metal sheets over a 650mm travel distance.
Secures oversized automotive or structural components during welding, utilizing the SUS420J2 stainless rod to resist shop-floor corrosion.
Drives heavy-duty diverter arms on high-mass pallet conveyors, relying on dual-end cushions to stop the 200mm piston smoothly.
Selecting this 200mm bore is appropriate when application thrust requirements exceed the 10053 N (at 0.5 MPa) capacity of the 160mm bore variant. If the full 15708 N is unnecessary, stepping down reduces physical size and air consumption. Because this model features a 650mm stroke, the extended unsupported rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, pair this cylinder with an external guide rail or utilize a dedicated guided cylinder to absorb lateral forces.
For interchangeability, match the 200mm bore, 650mm stroke, G3/4 port, and required mounting accessory (such as TC trunnion or LB foot brackets). Remember that the adjustable air cushions only decelerate the piston; they do not lock the load. If the machinery loses air pressure, the piston will drift. To safely hold a load in place without continuous live pressure, integrate an external pilot-operated check valve or select the SAIL air-released lock variant.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X650-S generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552 (which supersedes ISO 6431). Match the 200mm bore, 650mm stroke, and G3/4 port size for a direct drop-in replacement.
