The AirTAC AirTAC SAI200X450 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 450mm 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 SAI200X450 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N push force at 0.5 MPa, this 200mm bore unit is built to move substantial loads across its 450mm stroke. The extruded aluminum barrel design eliminates protruding tie rods, providing a clean profile that simplifies mounting and tooling access.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in demanding environments. It utilizes PT tapered port threads and lacks a standard magnet. For applications requiring pneumatic end-position holding, the SAIL variant with an air-released lock is recommended over the standard cushioning.

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 high clamping force required to hold large steel plates securely in place during heavy-duty stamping and hydraulic press operations.
Drives large-scale diverter gates on mining or aggregate conveyor systems, moving heavy bulk materials reliably under harsh conditions.
Actuates heavy injection mold bases or large industrial tooling fixtures into position within substantial molding machinery.
Selecting this 200mm bore model is appropriate when the 160mm bore (10053 N at 0.5 MPa) cannot generate sufficient thrust for your heaviest material handling tasks. The 450mm stroke falls within the standard limit of 1500mm for this bore, operating at a maximum speed of 30-500 mm/s.
Because this stroke length is 450mm, the unsupported rod is susceptible to bending under side loads. Implementing an external guide rail or switching to a guided cylinder will prevent premature rod-bearing wear. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching the 200mm bore, 450mm stroke, PT G3/4 ports, and standard mounting accessories like the TC trunnion.
Quick checklist
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. It can reach up to 21991 N push force at 0.7 MPa.
Yes, the SAI200X450 is dimensionally interchangeable per ISO 15552 standards. It matches the standard 200mm bore, 450mm stroke, and G3/4 port sizing, allowing it to serve as a drop-in replacement for other ISO 15552 profile cylinders.
