The AirTAC SAI32 Standard Cylinder SAI32BX450 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X450 is a double-acting ISO 15552 profile cylinder engineered for a 32mm bore and 450mm stroke. It generates 402N of push force at 0.5 MPa, extending to 724N at 0.9 MPa, making it well-suited for moderate load positioning over longer distances.
This configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, relying instead on its extruded aluminum barrel with dual sensor grooves for straightforward mounting of external switches if needed later.

Extends 450mm to push medium-weight cartons off a main conveyor line, utilizing the 724N peak thrust at 0.9 MPa for positive actuation.
Cycles lightweight product layers onto a waiting pallet, where the SUS304 rod provides reliable performance in damp packing areas.
Moves workpieces from an initial feed chute to a machining center over a 450mm gap, keeping the cycle time fast within the 30-800 mm/s range.
Choose this 32mm bore when a compact footprint is required but the application demands a 450mm extension, generating 402N at 0.5 MPa. If your load requires less force, stepping down is not an option below 32mm in the SAI line, but stepping up to the 40mm bore (628N at 0.5 MPa) provides a 56% thrust increase if margins are tight.
Because the 450mm stroke creates a long unsupported rod extension, side loads can cause severe rod-bearing bending and premature seal wear. Use an external guide rail or a guided cylinder to absorb lateral forces. For dropping or suspending loads, note that the adjustable air cushions only decelerate the piston at end-strokes; they will not hold the load if air pressure drops. Use the SAIL locking variant or an external pilot check valve for fail-safe holding. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 32mm bore, 450mm stroke, PT port configuration with LB foot or FA flange mounts.
Quick checklist
The SAI32X450 generates a maximum push force of 724N at 0.9 MPa, with a pull force of 345N at 0.5 MPa.
Yes. The SAI32X450 is built to the ISO 15552 standard, meaning its mounting dimensions, 32mm bore, 450mm stroke, and PT port are fully interchangeable with equivalent ISO 15552 profile cylinders from other manufacturers.
