About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75S
The AirTAC SAIJ160X230-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7MPa. Its SUS304 stainless steel rod (code B) provides excellent corrosion resistance, while the integrated magnet (-S) enables precise position detection with CMSE reed and DMSE electronic sensors. A PT tapered port ensures a robust, leak-free pneumatic connection.
This model features a 230mm nominal stroke that can be fine-tuned down by up to 75mm, creating a usable travel window of 155-230mm. The rear screw acts purely as a mechanical stop to set the end position during commissioning; it does not lock the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 155-230mm window during machine setup, allowing rapid accommodation of new product dimensions without swapping cylinders.
Heavy Forming Positioning
Leverage the 14074N push force at 0.7MPa to execute powerful pressing or forming tasks, using the rear stop to prevent over-travel and ensure consistent depth.
Corrosive Assembly Lines
Utilize the SUS304 stainless steel rod and 155-230mm adjustable travel to drive clamping mechanisms in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75S the Right Cylinder?
Select this 160mm bore cylinder when an application requires heavy thrust up to 14074N at 0.7MPa, but stepping up to a 200mm bore (21991N at 0.7MPa) would be excessive. Choose the SAIJ adjustable-stroke configuration over a fixed SAI model when you need variable end-stops for product changeovers. To replicate this exact ISO 15552 replacement, match the 160mm bore, 230mm stroke, 75mm adjustment, PT port thread, SUS304 rod, and -S magnet.
Because the nominal stroke is 230mm, ensure adequate external guiding to handle side loads, as the 40mm rod diameter alone cannot support high lateral forces. For load-holding without continuous air pressure, the rear adjuster is insufficient; consider an external rod lock or pilot-operated check valve.
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 SAIJ160BX230-75S FAQ
At 0.7MPa operating pressure, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. At 0.5MPa, the push force is 10053N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its 230mm nominal length by up to 75mm. This creates a usable travel window of 155-230mm for fine-tuning end positions, but it does not lock the load without live air pressure.
