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 pneumatic applications. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 270 mm stroke provides the extended travel needed for large-scale forming, lifting, or clamping operations.
This actuator features a robust extruded aluminum barrel without tie-rods and includes standard PT tapered port threads. The piston rod is constructed from carbon steel for high tensile strength under heavy axial loads. Additionally, the barrel integrates dual sensor grooves, allowing for direct mounting of CMSE or DMSE series switches if a magnet is specified later.

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 massive 15708 N push force required to operate large metal stamping presses and heavy forming dies.
Ideal for actuating large-scale robotic welding fixtures and heavy component positioning systems on automotive lines.
Drives heavy-duty lift and push mechanisms for manipulating fully loaded pallets in high-throughput logistics centers.
Selecting this 200 mm bore cylinder is appropriate when forces between 15000 N and 28000 N are required, bridging the gap between the 160 mm bore (14074 N push at 0.5 MPa) and specialized hydraulics. Because the 270 mm stroke exceeds 300 mm, it is approaching a threshold where side loads can cause rod-bearing bending; utilizing an external guide rail or a guided cylinder body is recommended to prevent premature wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders for straightforward drop-in replacement. Mounting is highly versatile, supporting FA/FB flanges, CA/CB clevises, and TC trunnion brackets. Note that the adjustable air cushions at both ends decelerate the piston but do not hold a load; if static holding is required without air pressure, consider the SAIL or BSAI variants.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X270 generates a push force of 15708 N and a pull force of 15080 N. At 0.9 MPa, the push force increases to 28274 N.
Yes, the SAI200X270 is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it a drop-in replacement for other ISO 15552 cylinders, utilizing PT port threads and standard trunnion or flange accessories.
