The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX650-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 650mm 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 SAIJ32X650-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm, creating a precise 550-650 mm usable window.
Equipped with a SUS304 stainless steel rod (code B) for superior corrosion resistance, this unit omits the FB, CA, CB, and CR mounting options, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

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.

Dial in the 550-650 mm travel window during format changes on packaging lines, using the rear screw to set exact retract distances without changing hardware.
Adjust the stroke on the fly for sorting diverter arms that handle different package sizes, ensuring precise positioning at the end of travel.
Fine-tune the final resting position of a tooling head during initial commissioning, absorbing mechanical tolerances by trimming up to 100 mm off the nominal stroke.
Choose this 32 mm bore when an application requires fine-tuning the retract end-point during commissioning or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder or bolt on external stops. If your process needs more thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
Because the 650 mm stroke is relatively long for this bore size, the 12 mm rod should be guided externally to prevent excessive side-loading and premature seal wear. To replace an ISO 15552 cylinder, match the 32 mm bore, 650 mm stroke, 100 mm adjustment, PT G1/8 port, and your required mounting bracket. For load-holding without continuous air pressure, consider an external rod lock or the SAIL/BSAI series instead of relying on this adjuster.
Quick checklist
The rear adjuster screw lets you shorten the 650 mm nominal stroke by up to 100 mm, providing a usable travel range of 550 to 650 mm. This stopper sets the end position but does not lock or hold the load without continuous air pressure.
