About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-40
The AirTAC SAIJ80X600-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 600mm nominal stroke by up to 40mm. This creates a highly useful 560-600mm usable travel window, enabling precise end-position tuning during commissioning without the need to physically swap the cylinder or bolt on external stops. It delivers a robust 2268N pull force at 0.5MPa, making it well-suited for moving heavy loads along a long axis.
This specific SKU is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in demanding environments. It features a PT tapered port thread and a 25mm rod diameter with an M20x1.5 thread, which handles side loads well, though at 600mm of travel an external guide is still recommended to prevent premature wear. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors if needed.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-40 Is Used
Machine Changeover
Dial in the 560-600mm travel window during product size transitions on a packaging line without physically swapping out the actuator.
Long-Stroke Diverting
Handles heavy conveyor diverting tasks using 2268N of pull force at 0.5MPa, with the rear stopper allowing fine-tuning of the exact reject position.
Harsh Environment Actuation
The SUS304 stainless steel rod provides the necessary corrosion resistance for actuation tasks in wash-down or chemically exposed factory settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-40 the Right Cylinder?
Choose this 80mm bore when you need high thrust forces that a 63mm bore cannot provide, as stepping up yields a significant jump from 1402N to 2268N pull force at 0.5MPa. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for machine changeovers or product-size adjustments on a line. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series instead.
This model is dimensionally interchangeable per ISO 15552 and matches the following configuration: 80mm bore, 600mm stroke, 40mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and no magnet. Because the stroke is 600mm, always use an external guide to support the load and mitigate rod side-load stresses.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80BX600-40 FAQ
The rear adjuster screw acts as a mechanical stopper that lets you shorten the effective travel from the 600mm nominal stroke down to 560mm. It sets the end position but does not lock the load without live air pressure.
At 0.5MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At the maximum 1.0MPa pressure, the push force reaches 4523N.
