About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75S
The AirTAC SAIJ160X750-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It generates 14074N of push force at 0.7 MPa, utilizing a robust 40mm piston rod. The integrated -75 adjustment code creates a precise 675-750mm usable travel window, allowing you to dial in the exact retract end-position without swapping out the entire unit.
This specific SKU features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper acts purely as a travel limit, meaning it will not hold a load safely without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75S Is Used
Heavy Press Tuning
Fine-tune the 675-750mm end-of-stroke position during machine commissioning to precisely set the pressing depth on heavy industrial assemblies.
Product Size Changeover
Quickly adjust the retract distance by up to 75mm when switching between different large-format product sizes on an automated packaging line.
Large Fixture Positioning
Leverage the 18095N push force at 0.9 MPa and SUS304 rod to move heavy stainless steel fixtures into exact alignment before a welding process.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX750-75S the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder (providing 3518N push at 0.7 MPa) lacks the rigidity and thrust for heavy moving masses. The adjustable 675-750mm window is ideal for product changeovers on a line, letting you fine-tune the end stop during commissioning rather than machining external hard stops. Because the 750mm stroke is substantial, always support the load with an external guide to prevent excessive side-loading on the rod.
For exact ISO 15552 replacement, match the 160mm bore, 750mm stroke, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster is a stop, not a lock; if the application requires true load-holding without continuous air pressure, integrate an AirTAC SAIL pneumatic lock or an external rod lock. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX750-75S FAQ
At 0.5 MPa it provides 10053N push and 9425N pull force. At 0.9 MPa, the push force increases to 18095N, with a maximum rated force of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 750mm nominal stroke by up to 75mm, creating a 675-750mm travel window. It acts as a mechanical stop to decelerate the piston and set the end position, but it does not lock the load without live air pressure.
