About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100S
The AirTAC SAIJ160X230-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for heavy-duty automation. It features a 160 mm bore generating 14074 N of push force at 0.7 MPa, alongside a SUS304 stainless steel rod (code B) for superior corrosion resistance. The integrated magnet (-S) enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed within the dual-side sensor grooves.
This model provides a nominal 230 mm stroke with a 100 mm adjustment range, yielding a usable travel window of 130 to 230 mm. This wide window allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder. The rear screw acts purely as a mechanical stop to set the travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100S Is Used
Heavy Press Tuning
Dial in the exact 130 to 230 mm pressing depth during machine commissioning to accommodate different material thicknesses without changing the cylinder.
Product Changeover Stops
Adjust the retract end-stop on the fly for varying package sizes on a packaging line, utilizing the 100 mm trim window to handle diverse product dimensions.
Corrosive Heavy Automation
Leverage the 10053 N push force at 0.5 MPa and SUS304 stainless steel rod for heavy-duty positioning tasks in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-100S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust, such as the 10053 N push force at 0.5 MPa, and you need flexibility to dial in the exact end-stop over a 130 to 230 mm window. If your setup demands less force, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa, whereas moving up to a 200 mm bore provides 15708 N. Because this is an adjustable-stroke variant, it is favored over a fixed SAI cylinder for machine setups requiring variable end-stops rather than rigid positioning.
To achieve a true ISO 15552 replacement match, confirm the 160 mm bore, 230 mm nominal stroke, 100 mm adjustment, PT tapered ports, and the -S magnet option. This profile cylinder supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without continuous air pressure, pair this cylinder with an external rod lock or choose the SAIL or BSAI series instead of relying on the rear stopper. Furthermore, the 230 mm stroke is well within standard limits, but always ensure external guides support the load to minimize side-load stress on the M36x2 rod thread.
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 SAIJ160BX230-100S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N, and it reaches a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 230 mm by up to 100 mm, creating a usable stroke window of 130 to 230 mm. This stopper only sets the end position and does not lock or hold the load without live air pressure.
