The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 145mm 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 SAIJ32X145-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the nominal 145 mm travel by up to 40 mm for a precise 105-145 mm usable window. The extruded aluminum barrel features dual sensor grooves, allowing you to mount CMSE reed or DMSE electronic switches directly without extra brackets.
Because the rear stopper acts strictly as a travel end-deceleration device rather than a locking mechanism, the cylinder requires continuous live air to maintain its position under load. For applications needing true load-holding without pneumatic pressure, consider an external pilot-operated check valve or the AirTAC SAIL lock variant instead.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Quickly adjust the 105-145 mm travel window during product size changes without replacing the cylinder or adding external mechanical stops.
Fine-tune the retract end position at commissioning to perfect part ejection or clamping depth on precision assembly lines.
Accommodate varying package sizes on a conveyor by dialing in the exact stroke needed to push items into the correct lane.
Selecting this 32 mm bore makes sense when your machine setup requires exact end-position tuning during commissioning or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your application demands greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa; conversely, dropping to a smaller bore reduces footprint but sacrifices power. Since this unit features a PT port thread and lacks a magnet (-S), confirm your mounting and sensing requirements before ordering.
When replacing an ISO 15552 cylinder, verify that the 145 mm nominal stroke, 40 mm adjustment range, and G1/8 port size align with your existing manifold. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. As the 12 mm rod carries moderate side loads, ensure proper external guiding for the 145 mm travel to prevent premature seal wear.
Quick checklist
The rear adjuster screw allows you to shorten the effective travel by up to 40 mm, creating a usable stroke window of 105 to 145 mm. This lets you set the exact retract end position during setup without changing the cylinder.
