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 immense thrust, delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa. Its 55 mm stroke is a non-standard, made-to-order dimension tailored for short, high-power clamping or pressing operations.
This genuine AirTAC unit features a standard carbon steel piston rod and a built-in magnet (-S) for position detection. The extruded aluminum barrel includes sensor grooves on both sides, allowing seamless mounting of CMSE or DMSE reed switches without additional brackets.

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 form or stamp thick metal components within a very short 55 mm travel distance.
Secures large molds or heavy fabrication assemblies firmly in place during secondary machining or welding processes.
Ejects dense, heavy finished parts from press beds or molding cavities with rapid, decisive force.
Select this 200 mm bore when 15708 N at 0.5 MPa is required for brief, heavy-duty movements; if your application needs less force, consider dropping to the 160 mm bore, which provides 10053 N at 0.5 MPa. Because this is a non-standard 55 mm stroke, expect a made-to-order lead time.
For applications requiring the load to remain fixed without continuous air pressure, a standard SAI cylinder will drift; utilize the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock to secure the piston safely. This model uses PT tapered port threads and operates at speeds between 30-500 mm/s.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. It reaches a maximum theoretical force of 3204 kgf at 1.0 MPa.
Yes, the SAI200X55-S is built to the ISO 15552 standard, making its mounting interface dimensionally interchangeable with other ISO 15552 profile cylinders. It features a G3/4 port and uses a standard carbon steel rod.
