About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75S
The AirTAC SAIJ160X85-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 85 mm stroke that can be dialed back by up to 75 mm, yielding a highly flexible 10-85 mm usable travel window. Delivering 9425 N of pull force at 0.5 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for CMSE reed and DMSE electronic sensors.
The rear adjuster acts purely as a mechanical stop to fine-tune end positions during commissioning without adding external stops. It does not lock or hold the load without live air pressure; for load-holding applications, consider the SAIL or BSAI series. This extruded aluminum profile cylinder uses a PT tapered port and omits the FB, CA, CB, and CR mounting options, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75S Is Used
Variable End-Stop Tuning
Dial in the exact 10 to 85 mm travel window during machine commissioning to perfect pressing or clamping depths without swapping cylinders.
Product Size Changeover
Rapidly adapt the stroke length on automated lines processing different product sizes, using the rear screw to set new retract endpoints.
Heavy Assembly Positioning
Leverage the 10053 N pull force to move heavy pallets or tooling, relying on the stainless rod for durability in demanding industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-75S the Right Cylinder?
Selecting this 160 mm bore is ideal when your application requires the 10053 N pull force at 0.5 MPa (or 18095 N push at 0.9 MPa) but demands on-the-fly end-position tuning. If your setup only requires a fixed 85 mm stroke without commissioning adjustments, the standard SAI cylinder is a simpler choice. For loads needing secure holding without continuous air pressure, the SAIL (air-released lock) or BSAI (clamp-lock) variants are required, as the SAIJ adjuster is strictly a travel stop.
This specific configuration includes a -S magnet for position sensing and a SUS304 stainless steel rod for superior corrosion resistance. When integrating this model, ensure your ISO 15552 mounting interface matches the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 footprints, and note the PT tapered G3/4 port connection.

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 SAIJ160BX85-75S FAQ
The nominal stroke is 85 mm, but the rear adjusting screw allows you to shorten the effective travel by up to 75 mm. This creates a usable stroke window from 10 mm to 85 mm, enabling fine-tuning of the retract end position without external stops.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
