The AirTAC AirTAC SAI200X125-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 125mm 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 SAI200X125-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa, making it ideal for high-mass positioning over its 125 mm stroke. The extruded aluminum barrel design omits tie rods while maintaining strict ISO 15552 mounting dimensions.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It also features a built-in magnet (-S) enabling seamless integration with CMSE and DMSE sensor switches via the dual-side barrel grooves. Fluid must be filtered air, operating within a 0.15-1.0 MPa range.

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 21991 N output force at 0.7 MPa required to actuate large metal stamping presses and forming dies.
Secures heavy industrial molds in injection molding or heavy machinery setups using the robust 200 mm bore profile.
Drives heavy-duty positioning jigs and lifts large automotive chassis components reliably within a 125 mm travel range.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N (at 0.5 MPa) capacity of the 160 mm bore variant. It utilizes a PT G3/4 port and an M36x2 rod thread. For applications requiring position holding without sustained air pressure, note that the standard SAI lacks a mechanical lock; utilize the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants to prevent drifting or dropping.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders. Mounting accessories such as the CA/CB clevis or TC trunnion can be utilized to match existing fixture geometries.
Quick checklist
The SAI200X125-S cylinder generates a push force of 15708 N at 0.5 MPa and 21991 N at 0.7 MPa. The pull force at 0.5 MPa is 15080 N.
Yes, the SAI200X125-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders as a drop-in replacement.
