About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40
The AirTAC SAIJ32X160-40 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 402N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. The built-in adjustment screw allows you to trim the nominal 160mm stroke back by up to 40mm, creating a precise 120-160mm usable travel window for exact end-position tuning.
Because it is an extruded aluminum profile cylinder, it includes sensor grooves on both sides for CMSE or DMSE switches. The rear stopper lets you fine-tune the retract end at commissioning without swapping the cylinder or adding external stops. Remember the adjuster is a travel stop, not a lock; it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40 Is Used
Machine Setup and Changeover
Dial in the exact 120-160mm end position during product size changes without swapping cylinders or adding external shims.
Variable End Stops
Fine-tune the retract stroke on packaging lines to accommodate different carton sizes using the rear adjustment screw.
Commissioning Fine-Tuning
Trim up to 40mm of travel during initial machine commissioning to achieve perfect process alignment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX160-40 the Right Cylinder?
Choose this 32mm bore when your application requires 402N push force at 0.5 MPa. If you need more thrust, stepping up to the 40mm bore yields 628N. The adjustable stroke is ideal for machine setup and product changeover, letting you dial in the end stop on the fly instead of machining spacers. For load-holding without live pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster.
This SAIJ32X160-40 is dimensionally interchangeable per ISO 15552. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. The 12mm rod and M10x1.25 thread handle side loads well, but for this 160mm stroke you should still guide the load externally to prevent rod binding.
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 SAIJ32BX160-40 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster acts as a stopper that shortens the effective travel. For this model, you can trim the 160mm stroke by up to 40mm, giving a usable travel window of 120-160mm. It is a travel stop, not a lock, so it cannot hold a load without live air.
