The AirTAC AirTAC SAI200X70-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 70mm 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 SAI200X70-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for short-stroke pressing and heavy clamping tasks. The 70 mm stroke ensures rapid actuation without occupying excessive axial space.
This variant features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnet (-S), it supports direct mounting of CMSE or DMSE sensor switches in the dual extruded barrel grooves. Fluid compatibility is limited to filtered 40 um air, operating within a 0.15-1.0 MPa pressure range.

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 15708 N push force required to form thick-gauge metal components in automated stamping presses.
Ideal for seating large bearings or machinery bushings with a controlled 70 mm stroke and high rigidity.
Acts as a robust high-capacity stopper for heavy pallets on assembly lines, utilizing its 15080 N pull force to retract quickly.
Selecting this 200 mm bore cylinder is ideal when maximum thrust is required within a compact 70 mm stroke envelope. If the application requires slightly less force, stepping down to the 160 mm bore yields 10053 N of push force at 0.5 MPa while reducing physical footprint and air consumption. Conversely, the SAI200X70-S remains the top choice for loads approaching 15708 N.
Because the standard SAI design lacks an internal locking mechanism, the piston will drift if air pressure is lost or exhausted. For operations requiring strict load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. This model ensures seamless physical interchangeability with other ISO 15552 profile cylinders, utilizing a PT G3/4 port thread and standard mounting accessories like TC trunnion or LB foot brackets.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore 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 SAI200X70-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided you match the PT G3/4 port and mounting interface.
