The AirTAC AirTAC SAI200X400-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200mm bore unit utilizes a 400mm stroke to drive massive payloads in demanding industrial environments. The extruded aluminum barrel design omits tie-rods, providing a smooth exterior that resists contamination and simplifies cleaning.
Equipped with a standard magnet (-S), this model directly supports CMSE and DMSE proximity switches via integrated sensor grooves on both sides of the barrel. The piston rod is constructed from durable carbon steel, while the standard TPU seals handle operating pressures up to 1.0 MPa. For environments exceeding standard thermal limits, Viton (H) seals are available to maintain integrity at elevated temperatures.

Provides the immense 15708 N clamping force required to hold large metal sheets securely in place during heavy-duty stamping and punching operations.
Drives robust pressing and joining fixtures for oversized automotive or structural components, utilizing its 400mm stroke to accommodate varying part heights.
Actuates heavy-duty diverter gates and bulk material handling systems where high mass and friction demand exceptional pulling and pushing thrust.
Selecting this 200mm bore cylinder is appropriate when 160mm alternatives cannot supply the required thrust; stepping down to a 160mm bore reduces the 0.5 MPa push force to 10053 N. The SAI200X400-S operates within a 30-500 mm/s speed range, utilizing adjustable air cushions at both ends to decelerate the massive moving mass smoothly. It functions as a drop-in replacement for any ISO 15552 profile cylinder, matching the standardized 200mm mounting interface, G3/4 PT ports, and 400mm stroke dimensions.
Because the 400mm stroke generates significant leverage, an unsupported rod is highly susceptible to bending under side loads. Implementing an external guide rail or utilizing a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear. Furthermore, this standard actuator relies on continuous air pressure to maintain its position; if the pneumatic supply is lost, the load will drift. For fail-safe position holding, integrate an external rod lock or specify the BSAI bidirectional clamp-lock variant.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 21991 N.
No, a standard SAI cylinder will drop its load if air pressure is lost or exhausted. The adjustable air cushions only decelerate the piston at stroke end; they do not lock the position. For suspended load safety, use the BSAI clamp-lock variant or an external pilot-operated check valve.
