About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-75
The AirTAC SAIJ32X185-75 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 402N of push force and 345N of pull force at 0.5 MPa. It features a 12mm SUS420J2 stainless steel piston rod and PT tapered port threading. The integrated rear adjustment screw allows you to dial back the nominal 185mm stroke by up to 75mm, creating a highly versatile 110-185mm usable travel window for precise end-position tuning during commissioning.
This adjustable stopper is a travel end-setter, not a locking mechanism; it cannot hold a load without live air pressure. For position holding without continuous air, consider an external pilot-operated check valve or related AirTAC lock models like SAIL or BSAI. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR variants found on some standard ISO cylinders.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-75 Is Used
Machine Changeover
Dial in the exact end-stop position when switching product sizes on a packaging line, utilizing the 110-185mm travel window to adapt tooling heights instantly.
Commissioning Calibration
Fine-tune the retract position during initial machine setup without disassembling the cylinder or shimming the rear cover, saving setup time.
Variable End Stops
Set precise retract limits for assembly presses that need to accommodate multiple part lengths within the 75mm adjustment range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-75 the Right Cylinder?
Choose this 32mm bore when your application requires 402N of push force at 0.5 MPa. If your load demands less fine-tuning and lower force, stepping down to a 25mm bore (if available) or a smaller frame changes the footprint, while stepping up to a 40mm bore increases the force to 628N. The SAIJ32X185-75 is selected over a fixed-stroke SAI specifically when a 75mm adjustment window is needed to accommodate product size changeovers or machine setup variations without physically swapping the cylinder or adding external mechanical stops.
When ordering, confirm the bore (32), stroke (185), adjustment (75), PT port, and mounting style. Because this is a non-magnet variant, position sensing requires external methods rather than internal CMSE or DMSE switches. For any stroke near or exceeding 300mm, always use an external guide to prevent rod side-loading, though this 185mm stroke is well within the 1000mm maximum standard limit for the 32mm bore.
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 SAIJ32AX185-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 185mm down to as little as 110mm, providing a 75mm tuning window. It only sets the travel end and does not lock or hold the load without live air pressure.
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
