About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75
The AirTAC SAIJ32X100-75 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 402N of push force at 0.5MPa. Its 100mm nominal stroke can be dialed back by up to 75mm, creating a highly versatile 25-100mm usable travel window for precise end-position tuning during commissioning. This extreme adjustment range allows a single cylinder to cover multiple product sizes without swapping bodies.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 32mm bore unit features PT tapered ports and a 12mm rod thread. It shares the standard extruded aluminum barrel with sensor grooves on both sides, though it omits the FB, CA, CB, and CR mounting options found on some variants, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75 Is Used
Variable End-Stop Setup
Leverage the 25-100mm travel window to dial in the exact retract position on the fly, perfect for prototyping and short-run changeovers.
Multi-Product Handling
Adjust the stroke to match different package sizes on a single conveyor line without physically replacing the actuator or adding external stops.
Corrosive Environment Actuation
Utilize the SUS304 stainless steel rod in light chemical or washdown settings where standard carbon steel rods would fail prematurely.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-75 the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5MPa (or 563N at 0.7MPa) alongside extreme travel flexibility. If your setup needs less force, stepping down is not an option within the SAIJ range, but if you require higher thrust, the 40mm bore provides 628N at 0.5MPa. The 75mm adjustment range is ideal for machines running multiple product sizes, acting as a variable end-stop that replaces fixed SAI cylinders.
Because this is a double-acting cylinder, the rear adjuster and air cushions only decelerate the travel end; they do not hold the load without live air. For dead-stop holding, select an SAIL or BSAI cylinder. This SAIJ configuration uses a SUS304 rod and PT ports, and is dimensionally interchangeable with ISO 15552 cylinders.
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 SAIJ32BX100-75 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 563N.
The rear adjuster screw acts as a mechanical stop that lets you trim the 100mm nominal stroke back by up to 75mm, resulting in a usable travel window of 25-100mm. It sets the end position but does not lock the load without continuous air pressure.
