The AirTAC AirTAC SAI200X225 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 225mm 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 SAI200X225 is a double-acting ISO 15552 profile cylinder engineered for extreme thrust requirements, delivering 15708 N of push force at just 0.5 MPa. This 200 mm bore unit features a 225 mm stroke and utilizes a robust G3/4 PT tapered port thread to handle massive air volumes. Its extruded aluminum barrel design omits traditional tie-rods, providing a clean exterior that integrates seamlessly into heavy-duty machinery.
For environments requiring specific corrosion resistance or high temperatures, this model is configured with a standard carbon steel piston rod, though SUS304 stainless steel and Viton seal options are available across the series. The barrel includes dual-sided sensor grooves ready for CMSE or DMSE switches when a magnet is specified. Operating at up to 1.0 MPa, it provides a theoretical maximum force of 3204 kgf, making it ideal for pressing, lifting, and heavy clamping operations.

Provides the immense 15708 N push force at 0.5 MPa required to form thick gauge steel plates in automated stamping presses.
Delivers reliable, high-tonnage ejection force for large industrial injection molds, utilizing its 225 mm stroke to clear bulky parts safely.
Drives heavy structural components together in heavy machinery assembly lines, leveraging the 3204 kgf theoretical max force at 1.0 MPa.
Selecting the SAI200X225 is appropriate when forces exceed the 10053 N push capacity of the 160 mm bore variant at 0.5 MPa, provided your framework can accommodate the larger 200 mm ISO 15552 mounting footprint. This 225 mm stroke is highly effective for short, high-power movements, but because the stroke exceeds 300 mm in larger boores, you must manage side loads carefully—always use external guide rails or a guided cylinder carriage to prevent rod-bearing bending, as long unsupported rods flex under asymmetric loads.
Note that the adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not hold a load. If your application must maintain vertical position or resist drift when air pressure is lost or the valve is centered, you must integrate an external pilot-operated check valve or specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This cylinder serves as a direct dimensional drop-in replacement for any ISO 15552 standard cylinder, utilizing FA/FB flange or TC trunnion mounts with PT port threading.
Quick checklist
At 0.5 MPa, the SAI200X225 provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers a theoretical maximum force of 3204 kgf.
No, the standard SAI200X225 cannot hold a load without live air pressure. The adjustable air cushions only decelerate the piston at the stroke ends; they do not act as a brake. For load-holding, use the SAIL or BSAI variants, or add an external rod lock.
