About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10S
The AirTAC SAIJ160X85-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75-85 mm from its 85 mm nominal stroke. Delivering 10053 N of push force at 0.5 MPa, it handles heavy-duty positioning tasks. The integrated -S magnet supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves.
This variant features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and pairs with PT tapered port threads. The rear adjuster screw acts purely as a mechanical stop to fine-tune the end position without adding external stops; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10S Is Used
Machine Changeover
Dial in the 75-85 mm travel window during product size transitions without physically replacing the actuator or adding external stopper blocks.
Heavy Positioning
Leverage the 10053 N push force to move heavy pallets, using the fine-tune rear screw to perfect the final retracted position at commissioning.
Corrosive Assembly
Utilize the SUS420J2 stainless steel rod in humid or washdown assembly lines where standard carbon steel rods would degrade over time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-10S the Right Cylinder?
Choose this 160 mm bore when 10053 N of thrust at 0.5 MPa is required but the exact end-position needs on-site tuning. If your application requires less force, stepping down to a 125 mm bore yields 6136 N. The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the travel window without swapping the cylinder. For load-holding without continuous air pressure, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead, as the SAIJ adjuster is only a stop. To replace an ISO 15552 cylinder, match the 85 mm stroke, 10 mm adjustment, G3/4 port, and Basic/LB/TC mounting footprint.
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 SAIJ160AX85-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. It can achieve up to 18095 N push at 0.9 MPa.
The rear adjuster screw allows you to shorten the 85 mm nominal stroke by up to 10 mm, creating a 75-85 mm usable travel window. It functions as a mechanical end-stop for position tuning and does not hold the load without live air pressure.
