Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 165mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75
The AirTAC SAIJ32X165-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 402N of push force at 0.5 MPa. By integrating a 75mm adjustment mechanism at the retract end, this model allows you to dial down the nominal 165mm stroke to any effective travel distance within a 90-165mm window. This eliminates the need to physically swap out the barrel or bolt on external stops when fine-tuning end positions during machine commissioning.
Built with a SUS304 stainless steel piston rod and PT tapered port threads, it operates at speeds of 30-800mm/s and features variable air cushions at both ends. The rear adjuster acts purely as a mechanical travel stop to set deceleration and end-position, not as a load-holding lock; for applications requiring position maintenance without live air pressure, the SAIL or BSAI series should be used instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75 Is Used
Machine Changeover
Dial in the 90-165mm travel window on the fly to accommodate new product lengths during line changeovers without replacing the cylinder.
End-Stop Calibration
Use the rear adjuster to precisely set the retract position during initial commissioning, avoiding the need for external mechanical stops.
Variable Positioning
Ideal for assemblies requiring slightly different retract distances between cycles, providing a mechanically tuned reference point.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-75 the Right Cylinder?
Choose this 32mm bore adjustable-stroke unit when your application requires precise end-position tuning without the downtime of changing cylinders, stepping up from a smaller bore or down from a 40mm bore (which offers 628N at 0.5 MPa) depending on your exact force requirements. Because the 165mm stroke exceeds the 300mm threshold, note that long unsupported strokes still require an external guide to prevent rod side-loading, even with the robust M10x1.25 rod thread. To match this ISO 15552 interchangeable cylinder for a replacement, specify the 32mm bore, 165mm stroke, 75mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting (omitting FB/CA/CB/CR options), and no magnet.

- ✓ 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 SAIJ32BX165-75 FAQ
At an operating pressure of 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 165mm stroke by up to 75mm, creating a usable travel window of 90-165mm. This stopper sets the end position but does not hold the load without live air pressure.
