About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-75
The AirTAC SAIJ32X500-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 425-500mm usable travel window, letting you dial back the 500mm nominal stroke by up to 75mm during commissioning. Delivering 402N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic solid-state switches if a magnet is added later. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1 and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-75 Is Used
Machine Changeover
Quickly fine-tune the 425-500mm travel window during product size changes without replacing the cylinder or adding external mechanical stops.
Light Part Ejection
Provides 402N of push force at 0.5 MPa to reliably eject light parts from a moving conveyor line, with adjustable end-positioning.
Variable End-Stop Setup
Ideal for automated test fixtures where the exact retract distance needs precise dialing-in at commissioning via the rear stopper screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-75 the Right Cylinder?
Choose this 32mm bore when your application requires 402N push force at 0.5 MPa. If you need greater thrust, stepping up to the 40mm bore yields 628N. The 75mm adjustment window is ideal for product changeovers, allowing you to fine-tune the retract end-position without swapping the cylinder or bolting on external stops.
Because the 500mm stroke is long relative to the 12mm rod diameter, an external guide is recommended to prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI series. For a direct ISO 15552 replacement, match the 32mm bore, 500mm stroke, 75mm adjustment, PT ports, and the specified mounting style.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ32AX500-75 FAQ
At a 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the 500mm nominal stroke down to 425mm. It acts as a mechanical stop to fine-tune the end position and works alongside the standard air cushions, but it does not lock or hold the load without continuous air pressure.
