The AirTAC AirTAC SAI200X55 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 55mm 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 SAI200X55 is a double-acting ISO 15552 profile cylinder engineered for extreme thrust in compact actuation cycles. Operating at 0.5 MPa, it delivers 15708 N of push force and 15080 N of pull force, making it ideal for heavy-duty pressing and clamping over its 55 mm stroke. The extruded aluminum barrel omits tie rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
For harsh environments, this unit is equipped with a standard carbon steel piston rod and TPU seals. Should your application require resistance to higher thermal extremes, Viton (H) or NBR (N) seal alternatives are available. Note that this specific configuration uses PT tapered port threads and lacks a standard magnet; adding the -S suffix enables dual-side sensor grooves for CMSE or DMSE switches.

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.
Generates 15708 N at 0.5 MPa to securely hold and form thick gauge sheet metal in automated press lines.
Provides massive clamping force over a short 55 mm stroke to immobilize large fabricated weldments during robotic welding.
Delivers the high-impact push force necessary to break loose and eject heavy molded components from stationary tooling.
Selecting the 200 mm bore for a short 55 mm stroke maximizes output force without consuming excessive machine envelope space. If your application requires less energy or a smaller footprint, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa, which may suffice for medium-duty tasks. Because the stroke is well under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended if the load is offset.
This cylinder utilizes a G3/4 port and is dimensionally interchangeable with other ISO 15552 cylinders, allowing seamless integration with existing FA, FB, or TC mounting accessories. Remember that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold the load. If air pressure drops, the piston will drift. For fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the standard cushion.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X55 delivers a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X55 is a genuine ISO 15552 profile cylinder. Its standardized mounting interface and dimensions make it interchangeable with other ISO 15552 cylinders, allowing for seamless drop-in replacements using existing mounting hardware.
