The AirTAC AirTAC SAI200X550 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 550mm 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 SAI200X550 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It delivers a substantial pushing force of 15708 N at 0.5 MPa, making it well-suited for high-mass displacement over its 550 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that aligns with standard ISO 15552 mounting dimensions.
Built for demanding environments, this unit features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage the kinetic energy of large moving loads. While standard strokes extend up to 1500 mm for this bore, the 550 mm travel distance is a standard configuration.

Provides the immense 15708 N push force at 0.5 MPa required to actuate large mechanical presses and form thick metal components.
Utilizes its 550 mm stroke to safely push large molded parts clear of heavy machinery, ensuring automated removal without manual intervention.
Drives heavy-duty lifting platforms for vehicle chassis handling, relying on the robust 200 mm bore to move substantial dead weights.
Selecting this 200 mm bore cylinder is appropriate when applications require moving heavy payloads that exceed the 10053 N push force of the 160 mm bore at 0.5 MPa. If the full 550 mm stroke is unnecessary, dropping to a 100 mm bore yields 3927 N of push force at 0.5 MPa, which may suffice for lighter assemblies. This model operates at a maximum speed of 30-500 mm/s, reflecting the physical limits of moving large piston masses.
Because the 550 mm stroke generates a long unsupported rod extension, external guides or a fully guided cylinder are strongly recommended to prevent rod-bearing bending under side loads. Note that a standard SAI cylinder relies on live air pressure to maintain its position; if pneumatic supply drops, the piston will drift. For dead-load holding without continuous pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This unit uses PT ports and is dimensionally interchangeable with other ISO 15552 cylinders.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X550 provides a push force of 15708 N and a pull force of 15080 N. This scales up to 21991 N push force at 0.7 MPa.
Yes, the SAI200X550 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other standard ISO 15552 cylinders. It uses PT tapered ports and standard mounting accessories.
