The AirTAC AirTAC SAI200X25 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 25mm 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 SAI200X25 is a double-acting ISO 15552 profile cylinder engineered for immense thrust within a very compact movement range. It generates 15708 N of push force at just 0.5 MPa, making it ideal for heavy pressing operations that only require a brief 25 mm travel distance. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into existing ISO 15552 mounting footprints.
Built for demanding environments, this specific configuration utilizes a SUS304 stainless steel piston rod for superior corrosion resistance. Fluid ports feature PT tapered threading, and the assembly operates at speeds between 30-500 mm/s. While standard adjustable air cushions decelerate the piston at stroke ends, this massive bore can also be specified with Viton (H) seals for high-temperature applications up to +70 C.

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 robust 15708 N push force required to form thick gauge metal components within a tight 25 mm pressing distance.
Secures massive workpieces or heavy machinery frames during machining operations, utilizing its immense 200 mm bore power for unwavering hold.
Delivers rapid, high-impact force to set large rivets in structural steel fabrication, taking advantage of the 30-500 mm/s speed range.
Selecting this 200 mm bore with a minimal 25 mm stroke is optimal when a short, powerful clamping or pressing motion is required, avoiding the space consumption of longer strokes. If an application requires slightly less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa, which may better suit mid-weight loads while reducing physical envelope size. Because the stroke is well under 300 mm, rod-bearing bending from side loads is minimal, though external guides are still recommended for precise alignment.
As a true ISO 15552 standardized unit, this model ensures dimensional interchangeability with other ISO 15552 cylinders. Replacement matching relies on the 200 mm bore, 25 mm stroke, PT G3/4 port, and appropriate mounting accessories like TC trunnion or FA flange. Note that a standard SAI does not hold position upon loss of air pressure; if load holding is required for safety, specify the SAIL variant with an air-released lock or utilize an external rod lock.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X25 cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X25 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. Ensure your setup matches the 200 mm bore, 25 mm stroke, and G3/4 port size.
