About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75S
The AirTAC SAIJ160X85-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 10053N push force at 0.5 MPa. Its 75mm adjustment screw transforms the 85mm nominal stroke into a highly versatile 10-85mm usable travel window. This allows precise end-position tuning during commissioning without swapping out the entire actuator.
Built for demanding environments, this variant features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and carries PT tapered ports. The -S magnet enables seamless integration with AirTAC CMSE reed and DMSE electronic sensors via the dual-side barrel grooves. Remember that the rear adjuster acts strictly as a travel stop for deceleration, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75S Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 10 and 85mm during machine setup, accommodating multiple product sizes without adding external mechanical stops.
Heavy-Duty Forming Press
Leverage the 10053N push force at 0.5 MPa for high-load stamping or holding tasks, tuning the travel window to prevent over-travel on sensitive tooling.
Corrosion-Resistant Actuation
Utilize the SUS420J2 stainless steel rod in humid or mildly corrosive industrial environments where a standard carbon steel rod would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-75S the Right Cylinder?
Select this 160mm bore actuator when an application demands high force (10053N at 0.5 MPa) alongside variable end-stops, stepping up from a 125mm bore that yields 6136N. The adjustable 10-85mm window is ideal for product-size changeovers on a line. If the machine requires the load to be held without live air pressure, this cylinder is insufficient since the adjuster is only a stop; you would need an external rod lock, a SAIL pneumatic lock, or a BSAI clamp-lock cylinder instead.
To achieve a true ISO 15552 replacement match, verify the 160mm bore, 85mm nominal stroke, 75mm adjustment range, PT port threads, and the -S magnet option. Although the stroke is under 300mm, the 40mm rod diameter and M36x2 thread provide excellent rigidity, yet external guides remain recommended for heavy lateral loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160AX85-75S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder generates a push force of 10053N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to trim the 85mm nominal stroke back by up to 75mm, creating a usable travel window of 10-85mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
