The AirTAC AirTAC SAI200X250 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 250mm 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 SAI200X250 is a heavy-duty double-acting profile cylinder built to ISO 15552 dimensional standards. Delivering a substantial 15708 N push force at 0.5 MPa, this 200mm bore unit is engineered for high-impact industrial automation. The 250mm stroke provides ample travel for large-scale material handling and press operations.
This model features a robust extruded aluminum barrel with sensor switch grooves machined on both sides for straightforward position feedback integration. Equipped with a standard carbon steel piston rod and PT tapered G3/4 ports, it ensures reliable sealing and high flow rates. For environments experiencing thermal extremes, the standard TPU seals can be substituted with Viton high-temperature variants.

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 immense 15708 N push force required for forming, stamping, and heavy-duty pressing tasks in metalworking facilities.
Powers large-scale diverter arms and heavy-gauge pushers on mining or aggregate conveyor lines handling dense materials.
Secures massive structural components and thick steel plates during welding or machining operations with absolute rigidity.
Select this 200mm bore actuator when an application demands immense thrust that smaller bores cannot provide, such as 15708 N at 0.5 MPa. If your force requirements are lower, stepping down to a 160mm bore yields 10053 N at 0.5 MPa, which may offer a more compact and economical footprint. Because this 250mm stroke is below the 300mm threshold, standard rod-bearing bending is minimal, though side loads should still be minimized through proper mechanical alignment.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 actuators with matching 200mm bore, 250mm stroke, and G3/4 port specifications. To maintain a load without continuous air pressure, an external pilot-operated check valve or the specialized BSAI clamp-lock variant is required, as the standard adjustable air cushions only decelerate the piston at stroke ends and do not function as a holding brake.
Quick checklist
At 0.5 MPa operating pressure, this 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X250 is dimensionally interchangeable per ISO 15552. It can serve as a drop-in replacement for other ISO 15552 profile cylinders with the same 200mm bore, 250mm stroke, and G3/4 port dimensions.
