About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40
The AirTAC SAIJ160X55-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 55 mm travel by up to 40 mm. This creates a highly specific 15 to 55 mm usable window, giving you exact control over the retract end-position without swapping out the unit. It delivers substantial thrust, pushing 10053 N and pulling 9425 N at 0.5 MPa.
Built with a SUS304 stainless steel rod, this variant is tailored for environments where corrosion resistance is paramount. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if you add a magnet later. It uses a G3/4 port and omits the FB, CA, CB, and CR mounting styles, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40 Is Used
Heavy Press Tuning
Dial in the exact 15 to 55 mm retract distance during machine commissioning to prevent over-travel on heavy pressing tasks.
Product Changeover
Quickly adjust the end-stop by up to 40 mm to accommodate different product sizes on the line without changing the cylinder.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for heavy assembly operations in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-40 the Right Cylinder?
Selecting this 160 mm bore makes sense when your application requires heavy force—like the 10053 N push at 0.5 MPa—but demands on-site fine-tuning of the retract distance. If you need slightly less thrust, stepping down to a 125 mm bore yields 6136 N of push force; stepping up to a 200 mm bore provides 15708 N. Choose this adjustable SAIJ over a fixed SAI when you anticipate product changeovers or need to micro-adjust the end stop during commissioning without adding external stops.
For an exact ISO 15552 replacement match, ensure your specifications align with a 160 mm bore, 55 mm stroke, 40 mm adjustment range, PT tapered port thread, and the appropriate mounting bracket. Because the nominal stroke is only 55 mm, side-loading is less of a concern than with long-stroke cylinders, but you should still rely on external guides for heavy loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160BX55-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw lets you shorten the 55 mm nominal stroke by up to 40 mm, creating a usable travel window of 15 to 55 mm. This allows you to set the exact retract end-position at commissioning without external stops.
