About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75S
The AirTAC SAIJ32X165-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 90 to 165 mm usable travel window, allowing you to dial in the exact end position without swapping components. The 32 mm bore delivers 402 N of push force at 0.5 MPa, making it suitable for light-load positioning tasks.
This SKU is built with a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE or DMSE sensors. It uses PT tapered ports sized G1/8. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75S Is Used
Machine Changeover
Dial in the retract stop from 90 to 165 mm during product size changes without adding external stopper blocks to the machine frame.
End-Position Tuning
Fine-tune the final end position at commissioning to absorb mechanical tolerance stacks in the fixture without machining spacer plates.
Light-Load Diverter
Adjust the actuation length on a 402 N push force conveyor diverter to handle varying package sizes on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75S the Right Cylinder?
Select this 32 mm bore model when an application requires fine-tuning the retract end within a 90 to 165 mm window at machine setup. If you need greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Because this is a 165 mm stroke, ensure the load is guided to prevent excessive side-load wear on the 12 mm rod and M10x1.25 thread.
The rear adjuster acts solely as a travel stop to set deceleration, not as a lock. A plain SAIJ will not hold a load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve. To match this ISO 15552 replacement exactly, specify the 32 mm bore, 165 mm nominal stroke, 75 mm adjustment, PT ports, SUS304 rod, and the -S magnet.
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 SAIJ32BX165-75S FAQ
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N 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 nominal 165 mm down to 90 mm. This creates a 90-165 mm adjustable window for setting the exact retract end position during setup.
