About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10
The AirTAC SAIJ100X290-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a 10 mm reduction of its 290 mm nominal travel, creating a precise 280-290 mm usable window. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward detection integration.
This specific configuration utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes PT tapered port threads. The rear adjuster functions strictly as a mechanical stop to dial in the end position during commissioning; it does not lock or hold the load without live air pressure. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10 Is Used
Machine Setup Tuning
Dial in the exact end-of-stroke position within the 280-290 mm window during initial commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slight variations in product sizes on a production line.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move and position substantial masses accurately in automated assembly lines.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-10 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, as it provides 3927 N push force at 0.5 MPa, stepping up from the 63 mm bore which yields 1559 N. The 10 mm adjustable travel window is ideal for fine-tuning end stops during machine setup or product changeover without swapping out the entire cylinder. For any load-holding requirements without continuous air pressure, this cylinder is insufficient as the adjuster is only a stop; consider an AirTAC SAIL or BSAI series instead.
Because the 290 mm stroke exceeds the 300 mm threshold, it is crucial to ensure adequate external guiding to prevent excessive side-loading on the SUS304 rod, despite the robust M20x1.5 rod thread. To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 290 mm stroke, 10 mm adjustment, PT ports, and the desired mounting style.
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 SAIJ100BX290-10 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The SAIJ100X290-10 features a rear adjusting screw that allows you to shorten the effective stroke by up to 10 mm, providing a usable travel range of 280-290 mm. This mechanical stopper only sets the end position and does not hold the load without live air pressure.
