About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-40
The AirTAC SAIJ100X150-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 150mm nominal stroke that can be dialed back by up to 40mm, creating a precise 110-150mm usable travel window for exact end-position tuning during commissioning. Delivering 5497N of push force at 0.7MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads.
This adjustable model omits the FB, CA, CB, and CR mounting variants found on some standard cylinders, retaining a focused set of ISO 15552 interfaces: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops; it is not a locking mechanism and cannot hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-40 Is Used
Product Changeover
Dial in the 110-150mm travel window during format size changes on packaging lines without physically replacing the actuator.
End-Stop Tuning
Fine-tune the retract end-position at machine commissioning to precisely seat heavy components without adding external mechanical stops.
Variable Positioning
Handle varying material thicknesses on an assembly line by adjusting the stroke back up to 40mm to accommodate different part dimensions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-40 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust—such as 5497N at 0.7MPa—and variable end-stops. If your process needs less force, stepping down to an 80mm bore yields 3518N at 0.7MPa, whereas larger bores are overkill. The adjustable 110-150mm window is ideal for machine setups requiring frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For position holding without continuous air supply, consider an external rod lock or AirTAC SAIL/BSAI series instead of relying on this adjuster.
When replacing an ISO 15552 cylinder, match the 100mm bore, 150mm nominal stroke, 40mm adjustment, PT port thread, and the required mounting accessory from the supported set. Because the 25mm rod diameter handles high side loads well, it is robust, but always verify external guiding if heavy loads are attached.
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 SAIJ100 Adjustable Cylinder SAIJ100BX150-40 FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 40mm. This provides a usable travel window of 110-150mm, letting you set the exact retract end-position without swapping the cylinder.
At an operating pressure of 0.7MPa, the SAIJ100X150-40 provides a push force of 5497N and a pull force of 3681N. It can deliver up to 7068N push force at 0.9MPa.
