The AirTAC AirTAC SAI200X25-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 25mm 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 SAI200X25-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N of push force at just 0.5 MPa. Its extruded aluminum barrel omits traditional tie-rods for a sleeker profile, while the 25 mm stroke provides rapid, short-travel actuation in heavy-duty clamping tasks. This specific configuration ships with a standard carbon steel piston rod and a built-in magnet for proximity sensing.
Because this is the -S variant, the cylinder seamlessly integrates with AirTAC CMSE and DMSE reed switches via the dual sensor grooves machined into both sides of the barrel. The standard TPU seals handle typical industrial temperatures, but you can specify Viton (H) or NBR (N) elastomers for specialized operating environments. Fluid must be filtered air, and the unit features adjustable air cushions at both ends to decelerate the massive payload at stroke extremes.

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 massive 15708 N force needed to seat large metal components and stamping dies securely in a single short 25 mm motion.
Ideal for high-force mold locking, utilizing the 200 mm bore to deliver rapid, high-pressure clamping over a compact 25 mm travel distance.
Drives short-stroke press brake assemblies where extreme tonnage is required instantly, leveraging the dual adjustable cushions for smooth stops.
Selecting this 200 mm bore over the neighboring 160 mm size increases your 0.5 MPa push thrust from 10053 N to 15708 N, providing the extra holding power required for forging presses or large mold actuation. The 25 mm stroke is optimal when you need maximum force over a very short distance without the rod-bearing bending risks associated with long strokes. To guarantee interchangeability during a machine retrofit, confirm the 200 mm bore, 25 mm stroke, G3/4 PT port thread, required mounting accessory (such as TC trunnion or FA flange), and the -S magnet specification.
Note that the adjustable cushions only serve to decelerate the piston near the stroke ends; they do not lock or hold a load. If your application requires vertical position holding without continuous air pressure, you must integrate an external pilot-operated check valve or select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X25-S is dimensionally interchangeable per ISO 15552 profile-barrel standards. You can replace competing ISO 15552 cylinders of the same 200 mm bore and 25 mm stroke by matching the G3/4 PT port and your specific mounting accessory.
