About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-40
The AirTAC SAIJ160X290-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a robust 160mm bore and a 290mm stroke. An integrated rear adjusting screw allows you to shorten the effective travel by up to 40mm, providing a precise 250-290mm usable window. This built-in stopper enables fine end-position tuning at commissioning without swapping out the entire unit or fabricating external stops. Delivering 14074N of push force at 0.7MPa, it handles substantial loads with ease.
This model is equipped with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It is important to note that the rear adjuster acts strictly as a travel stop and does not hold the load without continuous live air pressure. For load-holding requirements without air, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-40 Is Used
Heavy-Duty Pressing
Delivers 14074N of thrust at 0.7MPa for forming and pressing tasks, with the 40mm stroke adjustment allowing precise control over the final end-position depth.
Product Changeover Diverters
Ideal for packaging lines that switch between carton sizes, letting operators quickly dial the travel back from 290mm to 250mm via the rear stopper without changing the cylinder.
Robotic Material Handling
The SUS304 stainless steel rod provides excellent corrosion resistance for harsh washdown environments while moving heavy pallets or workpieces along the ISO 15552 footprint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-40 the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application requires the 10053N push force at 0.5MPa offered here, as stepping down to a 125mm bore yields only 6136N. The adjustable 250-290mm travel window is ideal for production lines that undergo frequent product-size changeovers, allowing operators to dial in the exact end-stop mechanically rather than reprogramming fixed SAI cylinders. When specifying your replacement, ensure you match the 160mm bore, 290mm nominal stroke, 40mm adjustment, PT port threads, and the SUS304 rod material.
Because the 290mm stroke approaches a length where leverage forces amplify, an external guide should be used to prevent excessive side-loading on the rod. Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations. Operating speed ranges from 30-500mm/s.
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 SAIJ160 Adjustable Cylinder SAIJ160BX290-40 FAQ
At a standard operating pressure of 0.5MPa, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.7MPa, the push force increases to 14074N.
The rear adjuster acts as a mechanical stop that lets you shorten the 290mm nominal stroke by up to 40mm, creating a 250-290mm usable travel window. It functions as a travel stop for end-position tuning, not a lock, and cannot hold a load without live air pressure.
