The AirTAC AirTAC SAI200X270 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 270mm 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 SAI200X270 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a push force of 15708 N at 0.5 MPa. Featuring a 200 mm bore and 270 mm stroke, it tackles massive actuation tasks with ease. This unit incorporates PT tapered port threads and a SUS304 stainless steel piston rod, ensuring superior corrosion resistance in harsh environments.
Because this model lacks the -S magnet suffix, it does not support direct magnetic position sensing. If your workflow requires end-of-stroke detection, you would need to specify the -S variant or utilize external mechanical switches. The adjustable air cushions at both ends absorb kinetic energy efficiently, while the extruded aluminum barrel provides a rigid yet lightweight structure.

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 pressing, bending, and stamping heavy metal components in fabrication plants.
Actuates massive bulkhead doors, heavy-duty diverters, and high-capacity lifting platforms in logistics distribution centers.
Drives large-scale clamping and positioning fixtures for chassis components, utilizing its 270 mm stroke to accommodate varied part sizes.
Selecting this 200 mm bore cylinder is appropriate when your application demands substantial thrust, such as 15708 N at 0.5 MPa or up to 21991 N at 0.7 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which might save space and air consumption. Conversely, this is the largest standard bore in the SAI series.
With a 270 mm stroke, the unsupported rod length is significant; always use external guides or a guided cylinder carriage to prevent rod-bearing bending under side loads. Remember that a standard SAI cylinder will drift if air pressure is lost. For applications requiring strict load holding without live pressure, consider the BSAI clamp-lock variant or an external pilot-operated check valve. To match this exact unit for an ISO 15552 drop-in replacement, specify a 200 mm bore, 270 mm stroke, G3/4 PT ports, and your preferred mounting accessory like the TC trunnion.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. If you increase the operating pressure to 0.7 MPa, the push force reaches 21991 N.
Yes, the SAI200X270 is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders with matching 200 mm bore, 270 mm stroke, and G3/4 port dimensions.
