The AirTAC AirTAC SAI200X400 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 400mm 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 SAI200X400 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Utilizing an extruded aluminum barrel, this tie-rod-less design delivers a substantial 15708 N push force at 0.5 MPa and 21991 N at 0.7 MPa. The 400 mm stroke provides the extended travel needed for large presses and heavy material handling.
Built for demanding environments, this specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance. Fluid connections use PT tapered threads, and while this unit lacks a magnet, the barrel includes dual sensor grooves allowing for CMSE or DMSE switches when position feedback is required. Adjustable air cushions at both ends absorb kinetic energy effectively within its 30-500 mm/s operating speed 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 massive 21991 N push force at 0.7 MPa required for actuating large stamping presses and heavy-gauge metal bending fixtures.
Drives robust joining and riveting stations for automotive or structural components, utilizing the 400 mm stroke to accommodate oversized workpieces.
Powers heavy-duty diverter arms and large-scale pallet sorting gates where high kinetic energy demands robust adjustable cushioning at stroke ends.
Selecting this 200 mm bore cylinder is appropriate when applications exceed the 10053 N push force of the 160 mm variant at 0.5 MPa, requiring maximum thrust. However, if the 400 mm stroke exceeds your actual travel requirement, stepping down to a 160 mm bore reduces both physical envelope and air consumption significantly.
Because the 400 mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending and premature seal wear. Implement an external guide rail or use a guided cylinder to absorb lateral forces. Furthermore, this standard SAI does not hold its load when air pressure is lost; if pneumatic failure risks dropping a heavy payload, integrate the BSAI clamp-lock variant or an external pilot-operated check valve. For ISO 15552 drop-in replacement, match the 200 mm bore, 400 mm stroke, G3/4 port, and appropriate mounting accessories like the TC trunnion.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X400 is dimensionally interchangeable per ISO 15552. You can drop it in place of other ISO 15552 profile cylinders with the same 200 mm bore, 400 mm stroke, and G3/4 port configuration.
