About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10
The AirTAC SAIJ100X180-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 170-180mm usable travel window, allowing you to dial back the nominal 180mm stroke by up to 10mm during commissioning. Delivering 3927N of push force at 0.5 MPa, it handles heavy positioning tasks with precision.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU omits the magnet, meaning electronic DMSE or reed CMSE sensors cannot be used without modification. The rear adjuster acts purely as a travel stop to fine-tune deceleration, not as a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10 Is Used
Press Fit Tuning
Dial in the exact 170-180mm insertion depth for press fits during machine setup, compensating for material thickness variations without swapping cylinders.
Product Changeover Stops
Adjust the retract end-position by up to 10mm on packaging lines to accommodate different product lengths quickly and repeatably.
Heavy Load Positioning
Leverage the 3927N push force at 0.5 MPa to move heavy pallets or fixtures, fine-tuning the stop point to match fixture tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-10 the Right Cylinder?
Choose this 100mm bore when 50mm cylinders (offering 982N at 0.5 MPa) lack the necessary thrust and an 80mm bore (2513N) is still insufficient. The 10mm adjustable range is ideal for applications requiring exact end-position tuning without adding external mechanical stops. For holding loads without live air pressure, select a SAIL or BSAI cylinder instead, as this SAIJ adjuster is only a stop.
When replacing an ISO 15552 cylinder, match the 100mm bore, 180mm stroke, 10mm adjustment, PT port, and basic mounting style. Because the 180mm stroke is relatively short for this bore, side-load risks are minimal, but an external guide is still recommended for heavy lateral loads.
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 SAIJ100BX180-10 FAQ
At 0.5 MPa it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, push force increases to 5497N. The operational speed range for this 100mm bore cylinder is 30-800 mm/s.
The rear adjuster screw lets you shorten the effective travel from 180mm down to 170mm. This allows precise end-position tuning at commissioning without changing the cylinder or adding external stops. The adjuster acts only as a travel stop and does not lock the load.
