About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-75S
The AirTAC SAIJ100X290-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa, utilizing a 25mm piston rod and G1/2 ports. With its 290mm nominal stroke and 75mm adjustment code, this model provides a usable travel window of 215-290mm, allowing you to fine-tune the retract end position at commissioning without adding external stops.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop to set the end position, not as a lock, so the cylinder will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-75S Is Used
Machine Setup & Changeover
Dial in the exact retract position within the 215-290mm window during machine commissioning or product family changeovers without swapping out the entire actuator.
Variable End-Stop Positioning
Adjust the stopping point on the fly for conveyor diverter arms or packaging flap folding mechanisms that handle multiple package dimensions.
Pressing & Forming Depth Control
Set precise mechanical bottom-dead-center limits for light-duty pressing or assembly tasks where the 3927N output at 0.5 MPa must halt at a specific, repeatable depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-75S the Right Cylinder?
Choose this adjustable-stroke SAIJ over a fixed-stroke SAI when your application requires variable end-stops or frequent product-size changeovers on a line. If you need less force, stepping down to an 80mm bore yields 2513N at 0.5 MPa; if you require greater thrust, moving to a 125mm bore provides 6136N. Because this cylinder has a 290mm stroke, you should use an external guide to prevent excessive side-loading on the 25mm rod and rod thread during extended travel.
For an exact ISO 15552 replacement match, verify the 100mm bore, 290mm stroke, 75mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your application requires true load-holding without continuous air pressure, consider an AirTAC SAIL (air-released lock), BSAI (clamp-lock), or an external rod lock.
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 SAIJ100BX290-75S FAQ
The 75mm rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 290mm nominal stroke down to 215mm. It sets the end position but does not lock the load without live air pressure.
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N, with a maximum rated force of 801 kgf at 1.0 MPa.
