The AirTAC AirTAC SAI200X850 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 850mm 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 SAI200X850 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N, making it suitable for moving massive payloads across its 850 mm travel distance.
This large-bore actuator features a robust SUS420J2 stainless steel piston rod (material code A) for superior corrosion and wear resistance in demanding environments. It utilizes PT tapered port threading and operates at a controlled speed range of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback, and the adjustable air cushions at both ends ensure smooth deceleration of heavy masses.

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 thrust at 0.5 MPa required to actuate large mechanical stamping presses and form thick steel plates.
Drives heavy structural frames and chassis components along the 850 mm stroke with smooth deceleration provided by adjustable air cushions.
Shifts fully loaded industrial pallets or heavy material bins within automated distribution and warehousing lines.
Selecting this 200 mm bore actuator is ideal when a system requires moving heavy loads that exceed the 10053 N push force of the 160 mm bore variant. For an 850 mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
To match this ISO 15552 dimensionally interchangeable profile cylinder for a drop-in replacement, verify the 200 mm bore, 850 mm stroke, G3/4 port size, and the required mounting accessory (such as TC trunnion or FA flange). Because a standard SAI does not hold its position upon air loss, applications requiring fail-safe load holding should specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 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 SAI200X850 is a profile cylinder dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 cylinders by matching the 200 mm bore, 850 mm stroke, G3/4 port, and mounting interface.
