About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30
The AirTAC SAIJ32X165-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 135-165 mm usable travel window, allowing you to dial back the nominal 165 mm stroke by up to 30 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for electronic or reed switching.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30 Is Used
Product Changeover
Quickly fine-tune the 135-165 mm travel window during production line changeovers to accommodate slightly different package sizes without changing the cylinder.
Machine Setup
Dial in the exact end-stop position during initial commissioning using the rear adjuster, avoiding the need to add external shims or spacers.
Variable End Stops
Ideal for light-duty conveyor diverters where the 402 N push force is sufficient and the exact retraction point needs occasional field adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping out physical components; its 30 mm adjustment window easily accommodates product changeovers. If your setup needs greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. Because the stroke is 165 mm, external guidance is recommended to manage side loads.
This adjustable model is preferred over a fixed SAI cylinder when machinery requires variable end-stops. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air. For load-holding without pressure, consider an external pilot-operated check valve or the SAIL series. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ32BX165-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the nominal 165 mm down to 135 mm. It only sets the travel end and does not lock the load without live air pressure.
