About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30S
The AirTAC SAIJ160X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its integrated SUS304 stainless steel rod provides excellent corrosion resistance, while the PT tapered port ensures a reliable, leak-free connection. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
With a 65mm nominal stroke and a 30mm adjustment range, this model provides a usable travel window of 35-65mm. You can fine-tune the retract end position at commissioning without adding external stops or swapping the cylinder. The rear screw acts purely as a travel stop to set the deceleration point alongside the variable air cushion, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30S Is Used
Heavy-Duty Forming Stops
Dial in the exact 35-65mm retract position for heavy pressing or forming tasks, allowing precise end-stop tuning without machining new fixture components.
Product Size Changeover
Quickly adapt machinery to different product widths by adjusting the rear stopper screw on the fly, minimizing downtime between production runs.
Sensor-Driven Positioning
Leverage the integrated -S magnet with DMSE electronic sensors to confirm the adjusted end position in automated assembly lines requiring high force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-30S the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high thrust (10053N push at 0.5 MPa) alongside precise end-position tuning. If you need less force, stepping down to a 125mm bore yields 6136N, but the SAIJ160X65-30-S is ideal for heavy-duty variable end stops. The adjustable 35-65mm window is perfect for product-size changeovers on a line. Because the stroke is relatively short, side-load risks are minimal, but the robust 40mm rod and M36x2 thread handle substantial loads. For load-holding without live pressure, consider an external rod lock or the SAIL/BSAI series.
To match this ISO 15552 interchangeable cylinder, confirm the 160mm bore, 65mm nominal stroke, 30mm adjustment, PT port thread, and the -S magnet for CMSE or DMSE sensors. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ160BX65-30S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 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 allows you to trim the effective stroke within a 35-65mm usable travel window. It functions as a mechanical stop to set the end position, but it is not a lock and cannot hold the load without continuous air pressure.
