About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-40S
The AirTAC SAIJ160X40-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, generating 10053N of pull force at 0.5 MPa, making it suitable for heavy-duty operations. The integrated -S magnet enables position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed in the dual-side extruded barrel grooves.
This specific SKU features a 40mm nominal stroke paired with a 40mm adjustment code, yielding a highly versatile 0-40mm usable travel window. Rather than machining custom short-stroke cylinders for each job, you can dial in the exact end position during commissioning. The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and fluid connections use PT tapered threads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-40S Is Used
Precision Clamping Setup
Dial in the exact 0-40mm clamping depth for delicate or variable-sized heavy parts without machining custom spacers or swapping actuators.
Automated Line Changeover
Rapidly adjust the retract end-stop during product size transitions on a conveyor line, minimizing downtime and avoiding external stopper hardware.
Heavy-Duty Positioning
Leverage the 10053N pull force to shift heavy industrial loads into precise final positions using the integrated rear stroke adjustment screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-40S the Right Cylinder?
Choose this 160mm bore cylinder when an application demands high force within a very compact travel distance, stepping up from a 125mm bore that provides 5734N pull force at 0.5 MPa. The adjustable stroke is perfect for product changeovers on a line, allowing operators to fine-tune the retract end-position via the rear screw stopper without swapping out the entire actuator. Because the nominal stroke is under 300mm, external side-load guides are less critical than on longer strokes, though the robust 40mm rod and M36x2 thread naturally handle high mechanical stress.
For an exact ISO 15552 replacement match, verify the 160mm bore, 40mm stroke, 40mm adjustment range, PT port thread, and the -S magnet option. Remember that the rear adjuster functions strictly as a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. If true load-holding is required, consider the SAIL air-released lock or BSAI clamp-lock variants. This profile cylinder 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 SAIJ160BX40-40S FAQ
The rear adjuster acts as a mechanical stopper that lets you trim the effective travel anywhere within a 0-40mm window from the 40mm nominal stroke. It allows fine-tuning of the end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 10053N of pull force and 14074N of push force. The maximum thrust at 1.0 MPa is 2050 kgf.
