The AirTAC AirTAC SAI200X550-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 550mm 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 SAI200X550-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers an impressive 21991 N of push force at 0.7 MPa, making it well-suited for moving substantial masses over its 550 mm stroke. The extruded aluminum barrel omits traditional tie-rods, providing a clean exterior and high structural rigidity.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid industrial environments. It also features a built-in magnet (-S) for use with CMSE and DMSE reed switches, which seat directly into the sensor grooves machined on both sides of the barrel. Porting follows the tapered PT thread standard, ensuring a reliable, mechanically sealed pneumatic connection.

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 push force required to actuate large press dies and form heavy-gauge sheet metal components.
Shifts heavy injection molds or tooling blocks along a 550 mm stroke, utilizing external guide rails to prevent rod deflection.
Pushes fully loaded pallets weighing several hundred kilograms off high-throughput packaging lines with consistent force.
Selecting this 200 mm bore cylinder is appropriate when an application requires pushing forces near 21991 N at 0.7 MPa. If your load requirements are lower, stepping down to the 160 mm bore yields 14074 N at the same pressure, which may reduce air consumption. Because the 550 mm stroke is substantial, the unsupported rod length is significant; heavy side loads will cause rod-bearing bending and premature seal wear. Always utilize an external guide rail or a dedicated guided cylinder to support the payload.
This model serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders. To match this exact unit, specify a 200 mm bore, 550 mm stroke, G3/4 (PT) port, and the -S magnet option. Note that the standard adjustable air cushions only decelerate the piston near the stroke ends; they do not hold a load. If your process requires dead-stop position holding without live air pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
Quick checklist
At an operating pressure of 0.7 MPa, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. At 0.5 MPa, the push force is 15708 N.
No, you must not subject the rod to heavy side loads. Over a 550 mm stroke, side loading will cause rod-bearing bending. You should use an external guide or a guided cylinder to support the payload.
