The AirTAC AirTAC SAI200X900 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 900mm 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 SAI200X900 is a double-acting ISO 15552 profile cylinder built for heavy-duty positioning. It delivers a substantial 15708 N push force at 0.5 MPa, scaling up to 21991 N at 0.7 MPa. The 900 mm stroke provides the extended travel needed for large-scale automation, pressing, and material handling tasks.
Configured with a SUS304 stainless steel rod (option B), this unit resists corrosion in humid or chemically exposed environments. It features PT tapered ports and lacks a standard piston magnet, relying purely on its extruded aluminum barrel and adjustable air cushions at both ends to manage the kinetic energy of its massive moving loads.

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.
Ideal for large metal forming presses requiring 15708 N of push force at 0.5 MPa over a long 900 mm stroke.
Moves heavy chassis components or fixtures along extended travel distances with smooth end-of-stroke cushioning.
Actuates large diverter gates or heavy pallet stops in high-capacity logistics and packaging lines.
With a 900 mm stroke, the unsupported rod length is highly susceptible to bending under side loads. For this bore size, you must use an external guide rail or a dedicated guided cylinder to prevent rod-bearing damage. If your application requires less push force, stepping down to the 160 bore yields 10053 N at 0.5 MPa, which may save space and air consumption.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops. The adjustable cushions only decelerate the piston near the end caps; they do not lock the rod. For fail-safe holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To replace an existing unit, match the 200 mm bore, 900 mm stroke, PT G3/4 port, and your required mounting accessory.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X900 is dimensionally interchangeable per ISO 15552. Match the 200 mm bore, 900 mm stroke, G3/4 port, and mounting interface for a drop-in replacement.
