The AirTAC AirTAC SAI200X425 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 425mm 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 SAI200X425 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Delivering a substantial push force of 15708 N at 0.5 MPa and a pull force of 15080 N, this 200 mm bore actuator handles massive payloads with ease. The 425 mm stroke provides extensive linear travel for large-scale material handling.
Configured with a SUS304 stainless steel piston rod (option B), this model offers superior corrosion resistance for humid or chemically exposed settings. It lacks an embedded magnet, so external position sensing must be handled mechanically rather than using CMSE or DMSE switches in the dual sensor grooves.

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.
Ideal for applying massive 15708 N pressing forces in automotive assembly and heavy machinery fabrication.
Shifts substantial molds and tooling across 425 mm of travel in injection molding facilities.
Drives robust lifting and pushing mechanisms for oversized pallets in high-capacity logistics hubs.
With a 425 mm stroke generating high inertia, external guide rails are strongly recommended to prevent rod-bearing bending under side load. If your application requires less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa. For operations needing position holding without continuous air pressure, integrate an external pilot-operated check valve or transition to the BSAI bidirectional clamp-lock variant. This model features PT tapered ports and mounts via standard ISO 15552 accessories like TC trunnion or FA flanges.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X425 delivers a push force of 15708 N and a pull force of 15080 N. It can reach up to 21991 N at 0.7 MPa.
Yes, the SAI200X425 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the PT port and mounting interface.
