The AirTAC AirTAC SAI200X55-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 55 mm stroke is ideal for short, high-impact clamping or pressing tasks. As a genuine AirTAC component, it ensures robust performance in rigorous industrial environments.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion and scratch resistance. The -S suffix denotes an integrated magnet for use with CMSE or DMSE sensor switches, which mount directly into the dual grooves on the extruded aluminum barrel. Fluid connections use PT tapered threads, matching the G3/4 port size for optimal airflow in large-bore applications.

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 push force at 0.5 MPa required to form and stamp thick-gauge metal components in automated presses.
Secures heavy industrial molds and dies during injection or casting processes, utilizing the 55 mm stroke for rapid, high-force actuation.
Drives large bearings and bushings into heavy machinery housings, leveraging the precise short-stroke impact and SUS420J2 rod durability.
Selecting this 200 mm bore model is appropriate when applications demand maximum thrust, such as 15708 N at 0.5 MPa. If the full theoretical 3204 kgf at 1.0 MPa is excessive, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, offering a more compact footprint. The 55 mm stroke keeps the rod fully supported, minimizing side-load bending concerns.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost or exhausted. For dead-stop or fail-safe load holding, consider the SAIL pneumatic lock variant or the BSAI bidirectional clamp-lock cylinder. For ISO 15552 drop-in replacement, match the 200 mm bore, 55 mm stroke, G3/4 PT port, and add the -S magnet. Mounting options include TC trunnion or FA flange accessories.
Quick checklist
At 0.5 MPa, the SAI200X55-S delivers a push force of 15708 N and a pull force of 15080 N. The theoretical maximum force at 1.0 MPa is 3204 kgf.
No, the standard SAI cylinder will drift if air pressure is lost. For position holding without live pressure, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
