The AirTAC AirTAC SAI200X155-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it ideal for high-mass handling tasks requiring a 155 mm stroke. The extruded aluminum barrel design omits tie rods for a clean, robust exterior.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for position detection. The barrel features sensor grooves on both sides, allowing seamless direct mounting of CMSE or DMSE reed switches without additional brackets. Fluid connections use PT tapered threads, and the cylinder supports adjustable air cushions at both ends to manage kinetic energy.

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 15708 N push force at 0.5 MPa required to actuate large mechanical stamping presses and heavy gauge forming dies.
Drives large-scale positioning fixtures and heavy clamping arms in automotive body-in-white welding and assembly lines.
Acts as a high-capacity stopper or diverter for fully loaded heavy pallets on roller conveyor systems.
Selecting this 200 mm bore cylinder is appropriate when application forces exceed the 10053 N push capacity of the 160 mm bore variant. The 155 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard lead times. Because the stroke is under 300 mm, rod bearing bending from side loads is less critical, but heavy radial loads should still be guided externally to prevent seal wear.
This model is dimensionally interchangeable per ISO 15552 mounting interfaces, serving as a drop-in replacement for other ISO 15552 profile cylinders. It operates at speeds of 30-500 mm/s. Note that the standard SAI does not hold loads upon air loss; for fail-safe holding, specify the SAIL lock or BSAI clamp-lock variant.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 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 SAI200X155-S is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it interchangeable with other ISO 15552 cylinders, ensuring a straightforward drop-in replacement.
