The AirTAC AirTAC SAI200X155 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 155mm 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 SAI200X155 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore unit handles massive payloads with precision. The 155 mm stroke is a made-to-order dimension tailored for specific heavy machinery travel requirements. Its extruded aluminum barrel design omits tie rods, providing a clean exterior and integrated sensor grooves on both sides for flexible switch mounting.
This configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads for pneumatic connections. For applications requiring position holding without live air pressure, this standard cylinder will drift, so consider pairing it with the SAIL air-released lock variant to secure the load safely.

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 immense 15708 N push force required to actuate large mechanical presses and form thick metal sheets.
Drives heavy chassis positioning fixtures where the SUS304 rod offers reliable resistance against coolant and oil exposure.
Moves substantial injection molds into and out of presses, utilizing the robust 200 mm profile barrel for stability.
Selecting this 200 mm bore is ideal when 160 mm (10053 N at 0.5 MPa) cannot provide enough thrust for your heaviest lifting tasks. The 155 mm nonstandard stroke is manufactured to exact specifications, ensuring you only pay for the travel distance your machine requires. Because this is a profile ISO 15552 cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, matching the standard 200 mm bore, 155 mm stroke, PT port, and standard mounting accessories like the TC trunnion or FA flange.
Since the stroke is under 300 mm, rod-bearing bending stress from side loads is less pronounced than in longer strokes, but heavy masses still require external guiding. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not function as a brake or lock.
Quick checklist
At 0.5 MPa, it generates 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 3204 kgf.
No, the standard SAI cylinder will drift or drop under load without live pressure. The adjustable air cushion only decelerates the piston at stroke end. For fail-safe load holding, use the SAIL (air-released lock) variant or an external rod lock.
