About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75
The AirTAC SAIJ32X750-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 675-750 mm window without swapping the unit. Driven by filtered air through a G1/8 port, it delivers 402 N of push thrust and 345 N of pull thrust at 0.5 MPa. The extruded aluminum barrel incorporates sensor grooves on both sides, providing flexible mounting for CMSE or DMSE switches even though a magnet is not specified for this configuration.
This variant features a SUS420J2 stainless steel rod (material code A) paired with an M10x1.25 rod thread, offering improved corrosion resistance for humid environments. The rear adjustment screw acts purely as a mechanical travel stop to set the end position, meaning it does not hold the load without live air pressure. For applications requiring true load-holding, an external rod lock or a SAIL cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75 Is Used
Machine Changeover
Dial in the 675-750 mm travel window during product line changeovers to set new end positions rapidly without replacing the entire cylinder.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to absorb mechanical tolerances and achieve exact positioning without external spacers.
Variable Stops
Adjust the stroke on packaging or conveyor diverters to handle different package lengths on the fly using the 75 mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning during commissioning or frequent product-size changeovers, avoiding the need to bolt on external stops. If your process demands higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, whereas dropping to a smaller bore would sacrifice the 345 N pull force this model provides.
Because the 750 mm stroke is long relative to the 12 mm rod diameter, an external guide is strongly recommended to prevent excessive side-loading and premature seal wear. When matching an ISO 15552 replacement, verify the 750 mm stroke, 75 mm adjustment range, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.

- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 750 mm down to 675 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
