About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10S
The AirTAC SAIJ160X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 10053N of push force at 0.5 MPa. Its SUS304 stainless steel rod provides excellent corrosion resistance, while the integrated magnet (-S) enables precise position detection. By turning the rear screw, you can trim the effective travel within a 75-85 mm window, providing exact end-position tuning without swapping out the entire unit.
This bore size features a G3/4 PT port and operates at speeds between 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It is important to note that the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock; it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10S Is Used
Press Stroke Calibration
Dial in the exact 75-85 mm end-stop during machine commissioning to accommodate material thickness variations without adding external stopper blocks.
Product Size Changeover
Quickly adjust the rear travel stop on a production line when switching between different product sizes, utilizing the 10053N thrust for reliable actuation.
Corrosive Forming Operations
Leverage the SUS304 stainless steel rod and high force output for precise positioning in humid or mildly corrosive metal-forming environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10S the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 10053N thrust at 0.5 MPa but demands on-the-fly end-position tuning within a 75-85 mm travel window. If you need less force, stepping down to the 125 mm bore yields 6136N of push force, whereas moving up to the 200 mm bore provides 15708N. The adjustable stroke is ideal for machine setups requiring frequent product changeovers, offering finer control than a fixed-stroke SAI cylinder. For load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 85 mm stroke, 10 mm adjustment, PT G3/4 port, and the -S magnet. Mounting options for this SAIJ series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles. Because the stroke is under 300 mm, side-load stress is minimized, though the substantial 40 mm rod diameter naturally handles high bending loads well.

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 SAIJ160BX85-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 85 mm stroke by up to 10 mm. This creates a usable travel window of 75-85 mm for fine-tuning the end position at commissioning without replacing the cylinder.
