About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100
The AirTAC SAIJ100X150-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. By integrating a 100mm adjustment mechanism onto a 150mm nominal stroke, this actuator provides a highly flexible usable travel window of 50-150mm. This wide range allows operators to dial in exact end positions during commissioning or product changeovers without swapping hardware.
The rear adjuster functions purely as a mechanical stop to set the retraction endpoint, working alongside the standard air cushions to decelerate the load. It does not lock or hold the load without live air pressure; for true position holding, consider the SAIL or BSAI variants. This extruded aluminum profile cylinder supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100 Is Used
Variable End-Stop Configuration
Perfect for packaging lines running mixed product lengths, utilizing the 50-150mm travel window to reconfigure the retraction endpoint on the fly without adding external stops.
Machine Setup & Commissioning
Enables precise fine-tuning of the rear mechanical stop during initial machine build, ensuring exact positioning of heavy 3927N payloads without machining custom spacers.
Heavy-Duty Product Changeover
Ideal for automated manufacturing lines that frequently switch between product sizes, allowing operators to quickly dial back the stroke up to 100mm to accommodate varying material heights.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100 the Right Cylinder?
Select this 100mm bore actuator when an application demands high thrust combined with extreme stroke variability. If your setup requires less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, but the SAIJ100X150-100 guarantees 3927N push force for heavier payloads. The massive 100mm adjustment range is chosen over a fixed SAI cylinder when a machine must process multiple product sizes on a single line, allowing the end stop to be reconfigured rapidly. To replace an ISO 15552 cylinder, match the 100mm bore, 150mm stroke, PT port thread, and SUS304 rod material. Note that this configuration omits a magnet, so CMSE or DMSE sensors cannot be used without specifying the -S option.
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 SAIJ100BX150-100 FAQ
It features a rear mechanical screw that acts as a stop, allowing you to trim the effective travel from the nominal 150mm down to as little as 50mm, creating a 50-150mm usable window. The adjuster sets the end position and works with the air cushion to decelerate the load, but it does not hold the load without live air pressure.
At a standard operating pressure of 0.5 MPa, the SAIJ100X150-100 provides 3927N of push force and 3681N of pull force. If operated at 0.7 MPa, the push force increases to 5497N.
