The AirTAC AirTAC SAI200X450 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 450mm 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 SAI200X450 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Utilizing an extruded aluminum barrel, this tie-rod-less design generates 15708 N of push force and 15080 N of pull force at 0.5 MPa. The 450 mm stroke is well-suited for moving substantial masses across large machinery envelopes. A standard carbon steel piston rod provides the rugged durability required in demanding industrial environments.
Fluid compatibility is restricted to filtered 40 um air, operating within a 0.15-1.0 MPa pressure range. The barrel features sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though a magnet (-S) must be specified if position detection is required. For applications needing positive load holding during pressure loss, the BSAI clamp-lock variant offers a robust alternative to the standard cylinder.

Provides the robust 15708 N thrust needed to actuate large forming presses and heavy industrial machinery over a 450 mm travel distance.
Drives substantial palletized loads across wide conveyor gaps, relying on the G3/4 PT ports for high-volume air exchange and rapid cycling.
Positions heavy assembly platens with precision, utilizing adjustable air cushions to safely decelerate massive loads at stroke endpoints.
Selecting the SAI200X450 is appropriate when 15708 N of thrust at 0.5 MPa is required to move a load over a 450 mm distance. If the application demands less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa, which may improve cycle times and reduce air consumption. Because this stroke exceeds 300 mm, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder carriage is strongly recommended to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, this unit serves as a drop-in replacement matching the 200 mm bore, 450 mm stroke, G3/4 PT ports, and standard mounting accessory dimensions. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not act as a braking mechanism. If the load must be held without live air pressure, an external pilot-operated check valve or the SAIL locking variant is necessary.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X200 generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold position without live air pressure. The adjustable air cushions only decelerate the piston at stroke ends. For load holding, use an external rod lock or the AirTAC SAIL variant.
