The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 100mm 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 SAIJ32X100-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 100mm travel back by up to 50mm. This creates a highly flexible 50-100mm usable stroke window, letting you dial in the exact retract end-position during commissioning without swapping out the barrel or adding external stops.
This variant is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

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 adapt retract depth during product size changeovers using the 50mm adjustment window, eliminating the need to physically swap cylinders on the line.
Dial in the exact 50-100mm stroke requirement during commissioning to perfect positioning without relying on external mechanical stops.
Choose this 32mm bore adjustable cylinder when your machine setup requires variable end stops or frequent product changeovers, as the 50mm adjustment range provides exceptional flexibility for a compact frame. Because the stroke is 100mm, side-loading is minimal, though the 12mm rod and M10x1.25 thread still require standard alignment.
When replacing an ISO 15552 cylinder, match the 32mm bore, 100mm nominal stroke, 50mm adjustment requirement, PT G1/8 port, and your preferred mounting attachment. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. Since this unit lacks a magnet (-S), it will not directly support Hall effect or reed sensors without modification.
Quick checklist
The rear adjuster screw allows you to shorten the effective travel from the nominal 100mm stroke by up to 50mm, providing a usable stroke window of 50-100mm. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
