The AirTAC AirTAC SAI200X310-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 310mm 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 SAI200X310-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over its 310 mm stroke. The extruded aluminum barrel design omits tie-rods, offering a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a magnet (-S) for proximity sensing and uses a standard carbon steel piston rod. Sensors such as CMSE or DMSE fit directly into the dual sensor grooves machined into both sides of the barrel. For environments requiring higher heat resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) options, ensuring operational stability across the -20 to +70 °C temperature range.

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 thrust at 0.5 MPa needed to actuate large stamping presses and heavy-gauge metal forming dies over a 310 mm travel distance.
Ideal for driving robust assembly presses that require slow, high-force clamping of automotive or industrial components, operating safely within the 30-500 mm/s speed range.
Pushes fully loaded heavy-duty pallets or industrial containers along transfer lines, utilizing the magnet and CMSE sensors to confirm end-of-stroke positioning.
Selecting this 200 mm bore cylinder is appropriate when 15708 N of thrust at 0.5 MPa is required; stepping down to a 160 mm bore drops the output to 10053 N, which may be insufficient for massive inertia. Because the 310 mm stroke exceeds the 300 mm threshold, the extended carbon steel rod is susceptible to bending under side loads. To mitigate rod-bearing wear, implement an external guide rail or utilize a guided cylinder configuration to absorb lateral forces.
If the machinery loses air pressure, the adjustable air cushions at both ends will not hold the load in place—they only decelerate the piston near the stroke endpoints. For applications requiring true position holding without live pressure, integrate the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. To replace an existing unit, match the 200 mm bore, 310 mm stroke, G3/4 PT ports, and appropriate mounting accessories like the TC trunnion or FA flange.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. If pressure is increased to 0.7 MPa, the push force reaches 21991 N.
Yes, the SAI200X310-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 200 mm bore, 310 mm stroke, G3/4 PT ports, and your existing mounting hardware.
