About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40
The AirTAC SAIJ160X45-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 45 mm travel that can be fine-tuned backward by up to 40 mm, yielding an effective usable stroke window of 5 to 45 mm. This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threading.
Operating within a 30-500 mm/s speed range, this 160 mm bore generates 10053 N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40 Is Used
Product Changeover
Dial in the exact 5 to 45 mm travel end-stop during format size changes on packaging lines without replacing the actuator.
End-Position Tuning
Fine-tune the retract stroke at machine commissioning to absorb mechanical tolerances and achieve precise clamping.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for heavy-duty pressing or lifting tasks in environments requiring high corrosion resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-40 the Right Cylinder?
Choose this adjustable-stroke model when your application requires exact end-position tuning during commissioning or product changeover without swapping cylinders or adding external stops. If you need less force, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa. For load-holding requirements without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider an AirTAC SAIL or BSAI series instead.
To replace this ISO 15552 cylinder accurately, match the 160 mm bore, 45 mm nominal stroke, 40 mm adjustment range, PT G3/4 port, and the SUS304 (B) rod material. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ160BX45-40 FAQ
At a standard 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. It can reach up to 18095 N of push force at its maximum 0.9 MPa pressure.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm from the nominal 45 mm. This creates a usable travel window of 5 to 45 mm, enabling precise end-position tuning without changing the cylinder.
