The AirTAC AirTAC SAI200X375-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 375mm 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 SAI200X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a push force of 15708 N at 0.5 MPa, this 200 mm bore actuator handles massive payloads with precision. The 375 mm stroke provides extensive linear travel for large-scale material handling. An adjustable air cushion at both ends decelerates the piston smoothly.
This configuration includes a standard carbon steel piston rod and a built-in magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, allowing direct mounting of CMSE or DMSE reed switches. For elevated thermal demands, the seal stack can be upgraded to Viton (H) instead of the standard TPU.

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 up to 21991 N at 0.7 MPa to drive large metal forming and stamping presses.
Moves heavy bulk material diverter gates and large structural chutes in mining operations.
Actuates heavy-duty lifting platforms and large chassis positioning jigs on vehicle lines.
Step down to a 160 mm bore if your application requires closer to 10053 N of push force at 0.5 MPa, as the 200 mm unit may be oversized for lighter loads. The G3/4 PT port accommodates high airflow to maintain operational velocity. Because the 375 mm stroke exceeds 300 mm, the unsupported rod is vulnerable to bending under side loads; utilize an external guide rail or a guided cylinder carriage to prevent premature rod-bearing wear.
Dimensionally interchangeable per ISO 15552, this profile cylinder serves as a direct drop-in replacement for other standard tie-rod-less actuators. Note that the standard SAI does not hold a load safely upon air loss; for fail-safe holding, select the BSAI bidirectional clamp-lock variant or integrate an external pilot-operated check valve.
Quick checklist
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X375-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other 200 mm bore ISO 15552 actuators using standard mounting accessories.
