About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75
The AirTAC SAIJ160X230-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 155 to 230 mm window. Using a 160 mm bore, it delivers a substantial 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch placement.
This variant incorporates a SUS304 stainless steel rod for enhanced corrosion resistance and ships with PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or related SAIL series cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 155 and 230 mm during machine setup to accommodate varying product dimensions without changing the cylinder.
Changeover Commissioning
Use the 75 mm rear adjuster screw to rapidly reset the end-of-stroke position for new production runs, eliminating the need to bolt on external stops.
Heavy-Duty Forming
Leverage the 14074 N push force at 0.7 MPa for high-tonnage pressing and holding operations, tuning the travel limit to prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-75 the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application demands high force—delivering 14074 N push at 0.7 MPa—and precise end-position tuning without external stops. If your force requirements are lower, stepping down to the 125 mm bore yields 8590 N push at 0.7 MPa, while the massive 200 mm bore provides 21991 N for extreme loads.
The 75 mm adjustment range is ideal for product changeovers on a line, allowing the end-stop to be dialed back exactly without swapping the cylinder. When replacing an ISO 15552 cylinder, match the 160 mm bore, 230 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR). Because the 230 mm stroke is under the 300 mm threshold, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads.
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 SAIJ160BX230-75 FAQ
At a standard operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 230 mm stroke by up to 75 mm, creating a usable travel window of 155 to 230 mm. This stopper only sets the end position and decelerates the travel; it does not lock or hold the load without continuous live air pressure.
