The AirTAC AirTAC SAI200X140 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 140mm 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 SAI200X140 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. 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 moving large masses over its 140 mm stroke. The extruded aluminum barrel design omits tie rods, presenting a clean profile that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure actuation rather than electronic position sensing. For operations requiring elevated temperatures, the standard TPU seals can be swapped for Viton (H) alternatives.

Provides the high tonnage required to form thick metal sheets in automated stamping presses.
Actuates heavy-duty bending arms in industrial sheet metal fabrication machinery.
Drives robust lifting arms that shift fully loaded pallets in high-throughput logistics hubs.
With a 200 mm bore offering 15708 N of thrust at 0.5 MPa, stepping down to a 160 mm bore reduces the push force to 10053 N, while staying at 200 mm is necessary for loads exceeding 1500 kg. Because the stroke is under 300 mm, side-load stress on the rod bearing is moderate, though external guides are still recommended for heavy offset loads. The PT porting and ISO 15552 dimensions ensure seamless interchangeability with other standard profile cylinders.
If the machinery requires the load to remain suspended or fixed during a complete loss of air pressure, the standard SAI200X140 will drift and drop. Its adjustable air cushions only decelerate the piston at stroke ends and do not function as a locking brake. For fail-safe load holding, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 15708 N.
No, the standard SAI200X140 is double-acting and will drift if air is exhausted. The adjustable cushions only slow the piston at end-of-stroke and do not lock the load. Use the SAIL or BSAI variants for fail-safe holding.
