The AirTAC AirTAC SAI200X300 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 300mm 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 SAI200X300 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial handling. It delivers a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over its 300 mm stroke. The extruded aluminum barrel design omits tie rods, providing a rigid yet streamlined profile that drops directly into standardized ISO 15552 mounting footprints.
Beyond the standard specifications, this unit features a robust carbon steel piston rod for high tensile strength under extreme loads. The barrel incorporates dual sensor grooves, allowing for straightforward positioning feedback when paired with CMSE or DMSE switches, though a magnet (-S suffix) must be specified at order to enable this capability. For applications requiring position retention without continuous air pressure, the BSAI clamp-lock variant offers a secure mechanical hold.

Provides the intense 15708 N push force required to form thick steel plates in automated stamping presses.
Drives heavy industrial components together with precision over a 300 mm stroke in automotive manufacturing lines.
Lifts and positions fully loaded heavy-duty pallets at the end of high-throughput packaging conveyors.
Selecting the SAI200X300 is appropriate when 15080 N of pull force at 0.5 MPa is required for heavy lifting or pressing tasks. If an application demands slightly less force, stepping down to the 160 mm bore yields 9425 N of pull force, which may improve cycle times and reduce air consumption. Conversely, if the 300 mm stroke is insufficient, the 200 mm bore supports standard strokes up to 1500 mm.
Because this model features a 300 mm stroke, the extended carbon steel rod is susceptible to bending under side loads. Utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear. Furthermore, the adjustable air cushions at both ends only decelerate the piston near stroke endpoints; they do not function as a braking mechanism. If the load must be held securely during a loss of air pressure, an external pilot-operated check valve or the SAIL locking variant is necessary. Replacement mounting requires matching the 200 mm bore, 300 mm stroke, G3/4 PT ports, and appropriate accessories like TC trunnion or LB foot brackets.
Quick checklist
At an operating pressure of 0.5 MPa, this cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, the theoretical push force reaches 3204 kgf.
Yes, the SAI200X300 is dimensionally interchangeable per ISO 15552. It can serve as a drop-in replacement for other ISO 15552 profile cylinders, provided the G3/4 PT ports and mounting dimensions match your existing setup.
