The AirTAC AirTAC SAI200X275-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 275mm 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 SAI200X275-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Generating 15708 N of push force at 0.5 MPa, this 200 mm bore unit handles massive loads with a 275 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. Equipped with a -S magnet, it supports CMSE and DMSE sensor switches seated in the dual side grooves. It uses PT tapered port threads and adjustable air cushions at both ends to decelerate the payload smoothly.

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.
Drives large platens and heavy tooling where 15708 N of push force at 0.5 MPa is required to form thick materials.
Actuates multi-ton clamping arms in automotive assembly lines, utilizing the SUS304 rod to resist coolant and washdown chemicals.
Shifts heavy pallets or bulk material chutes, using adjustable air cushions to safely decelerate the massive 200 mm piston.
Select this 200 mm bore when a 160 mm cylinder falls short—yielding 15708 N push at 0.5 MPa compared to the 160 mm bore's 10053 N. If exact positioning is required, the 275 mm stroke is well below the 1500 mm maximum, keeping the unsupported rod length manageable. However, for any application approaching 300 mm or beyond, use external guides to prevent rod-bearing bending under side loads.
Because standard pneumatic cylinders drift when air pressure is removed, do not rely on the air cushion to hold a suspended load. If your fixture requires fail-safe holding without live pressure, integrate an external pilot-operated check valve or specify the BSAI bidirectional clamp-lock variant. To replace an existing unit, match the 200 mm bore, 275 mm stroke, G3/4 port, and your desired mounting accessory like the TC trunnion.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a theoretical maximum of 3204 kgf at 1.0 MPa.
Yes, the SAI200X275-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 200 mm bore, 275 mm stroke, and G3/4 port layout without machining.
