Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-40

The AirTAC SAIJ32X120-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to shorten the effective travel. It provides a usable stroke window of 80 to 120 mm, enabling precise end-position tuning at commissioning without adding external stops. In this configuration, the piston rod is constructed from SUS420J2 stainless steel (code A), and the fluid connections use PT tapered threads.

The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It is important to note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure.

When selecting this model, the 40 mm adjustment range is ideal for applications requiring variable end-stops or frequent product-size changeovers, offering flexibility that a fixed-stroke SAI cannot match. If your application requires higher thrust, stepping up to a 40 mm bore increases the push force at 0.5 MPa to 628 N. Conversely, if you need load-holding capabilities without continuous air pressure, this cylinder will not suffice; you should consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. To replace this ISO 15552 cylinder, match the 32 mm bore, 120 mm stroke, 40 mm adjustment, PT ports, and the SUS420J2 rod material.

The SAIJ32X120-40 supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because the 12 mm rod and M10x1.25 thread carry limited side-load capacity, external guiding is recommended for any heavy offset loads.
