The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75 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 a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ32X450-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel down by up to 75 mm. This yields a usable 375-450 mm stroke window, allowing precise end-position tuning directly at commissioning without swapping out the actuator or adding external stops. The 32 mm bore generates 563 N of push force at 0.7 MPa, fitting it for light-duty handling tasks.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance, and utilizes PT tapered port threads. It relies on variable air cushions at both ends to decelerate the moving piston. Keep in mind that this rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for dead-stop holding, consider a SAIL or BSAI variant.

Dial in the exact 375-450 mm end-stop during initial commissioning to perfect product placement without machining new hard stops.
Quickly shorten the cylinder travel by up to 75 mm to accommodate varying package lengths on a packaging conveyor line.
Apply up to 563 N of force at 0.7 MPa for delicate component seating, using the adjuster to limit travel and prevent part damage.
Choose this 32 mm bore when your application requires the 563 N push force at 0.7 MPa; stepping down is not an option below this size, while moving up to a 40 mm bore yields 879 N if your payload increases. An adjustable stroke is highly beneficial here over a fixed SAI cylinder because the 450 mm travel can be dialed back to 375 mm to accommodate product size changeovers on a line.
Because this 450 mm stroke exceeds 300 mm, the 12 mm diameter rod becomes a side-load risk if left unsupported—an external guide is strongly recommended to prevent premature seal wear. When specifying a replacement, verify the 450 mm stroke, 75 mm adjustment range, PT G1/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR brackets.
Quick checklist
At 0.7 MPa operating pressure, this 32 mm bore cylinder generates 563 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 450 mm nominal stroke by up to 75 mm, providing a usable travel window of 375-450 mm. It only sets the end position; it does not lock the load without live air pressure.
