The AirTAC AirTAC SAI200X50-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 50mm 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 SAI200X50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial 15708 N of push force at 0.5 MPa. This short 50 mm stroke is optimal for high-force clamping or pressing tasks within confined spaces. As a genuine AirTAC component, it ensures reliable performance.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and PT tapered port threads. The integrated magnet (-S) allows seamless installation of CMSE or DMSE sensors along the dual extruded barrel grooves, providing precise end-of-stroke detection.

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 immense 15708 N output force required for metal forming and heavy stamping presses.
Secures large fabricated components firmly in place during welding or machining operations.
Drives large molds and heavy platens where high peak force and short stroke movements are routine.
Selecting this 200 mm bore size is appropriate when the 160 mm bore class (10053 N push at 0.5 MPa) lacks the necessary power for your heavy load. The 50 mm stroke minimizes rod overhang, inherently reducing side-load stress on the rod bearing. For applications requiring position retention upon air loss, note that the standard SAI does not hold loads; consider the SAIL or BSAI locking variants.
To ensure a perfect ISO 15552 replacement match, verify the 200 mm bore, 50 mm stroke, G3/4 port, and required mounting accessories (such as CA clevis or LB foot brackets). The -S magnet is essential if your control system requires piston position feedback.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push at 0.7 MPa.
Yes, the SAI200X50-S is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with matching 200 mm bore and G3/4 port specifications.
