About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-40
The AirTAC SAIJ32X165-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 125 to 165 mm, allowing you to dial back the piston travel by up to 40 mm during commissioning. With a 32 mm bore, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This variant incorporates a SUS304 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a mechanical stop to set the retraction end-position, meaning it will not hold the load dynamically without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-40 Is Used
Machine Changeover
Fine-tune the 125 to 165 mm travel window on the fly to accommodate different product lengths without installing external stopper blocks.
Variable End Stops
Dial in the exact retraction point during commissioning to perfectly position lightweight 402 N push-force diverter arms.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in packaging lines where moisture or washdown chemicals are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-40 the Right Cylinder?
Select this 32 mm bore model when your application requires precise end-position tuning without swapping out physical cylinders. The 40 mm adjustment range is particularly useful for accommodating slight product size variations on a conveyor line. If your setup requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the total stroke is 165 mm, side-loading is minimal, but an external guide should still be used for heavy offset loads.
Choose this adjustable SAIJ over a fixed-stroke SAI when you need a variable end-stop for machine changeovers rather than a locked travel distance. To match this ISO 15552 cylinder for a replacement, verify the 32 mm bore, 165 mm nominal stroke, 40 mm adjustment range, PT G1/8 port, and the SUS304 rod material. For applications that require true load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
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 SAIJ32BX165-40 FAQ
At a 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 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 165 mm stroke by up to 40 mm, creating a usable travel window of 125 to 165 mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
