About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75
The AirTAC SAIJ160X85-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial force, pushing with 14074N and pulling with 9425N at 0.7 MPa. The external rear stopper allows you to fine-tune the end position at commissioning, creating a usable travel window between 10 and 85 mm without adding external stops. This cylinder features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
Unlike a fixed-stroke SAI, this model lets you trim the retract position dynamically during machine setup or product changeover. The rear adjuster acts purely as a travel stop and works alongside the 50 mm variable air cushions at both ends to decelerate the load. It is not a locking mechanism and will not hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic sensors if needed.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75 Is Used
Heavy Press Tonnage
Provides up to 18095N of push force at 0.9 MPa for high-tonnage pressing, forming, and riveting operations.
Product Changeover
Dial in the 10-85 mm travel window during line changeovers to accommodate varying product sizes without physical cylinder swaps.
Corrosive Assembly Lines
The SUS304 stainless steel rod stands up to washdowns and harsh environments in food, packaging, or chemical assembly lines.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75 the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (providing 3518N push at 0.7 MPa) is insufficient for your heavy-duty application. The 75 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, as it eliminates the need to swap cylinders to achieve different end positions. If your process requires true load-holding without continuous air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead of relying on the adjuster.
This cylinder uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. To replace an ISO 15552 cylinder, match the 160 mm bore, 85 mm nominal stroke, 75 mm adjustment range, PT port thread, and your required mounting interface. Note that while the 40 mm rod diameter handles high side loads well, any stroke over 300 mm requires an external guide rod.
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 SAIJ160BX85-75 FAQ
The rear adjuster is an external stopper screw that limits the retract travel. For this model, it provides a usable stroke window of 10 to 85 mm, allowing you to set the exact end position during commissioning without changing the cylinder.
At 0.7 MPa operating pressure, the 160 mm bore generates 14074N of push force and 9425N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 2050 kgf of push force.
