About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX185-10
The AirTAC SAIJ100X185-10 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to fine-tune the retract end position. It provides a usable travel window of 175 to 185 mm, letting you dial in the exact end-of-stroke position at commissioning without swapping out the hardware. Delivering 3927 N of push force at 0.5 MPa, it fits robust automation needs.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It uses a G1/2 port and omits the FB, CA, CB, and CR mounting accessories, offering the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes dual sensor grooves, though this specific unit ships without a magnet.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX185-10 Is Used
End-Position Tuning
Dial in the exact 175-185 mm retract position during machine commissioning to perfect product alignment without adding external stops.
Product Changeover
Quickly adjust the travel end-stop by up to 10 mm when switching between slightly different product sizes on the same conveyor line.
Corrosive Environments
Leverage the SUS304 stainless steel rod for high-thrust pressing or clamping tasks in washdown or chemically exposed manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX185-10 the Right Cylinder?
Select this 100 mm bore actuator when an application requires high thrust—stepping down to a 63 mm bore drops your 0.5 MPa push force to 1559 N, while this 100 mm unit provides 3927 N. The 10 mm adjustment range is ideal for product-size changeovers on a line, giving you a variable end-stop instead of a fixed 185 mm stroke. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider an external rod lock or the AirTAC SAIL series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 185 mm stroke, 10 mm adjustment, PT tapered port threads, and the required mounting accessory. Because this is a profile cylinder rather than a tie-rod design, it maintains dimensionally interchangeable ISO 15552 mounting interfaces without claiming direct equivalence to other brands.
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 SAIJ100BX185-10 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N of push force at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective travel from the nominal 185 mm down to 175 mm. This creates a 175-185 mm adjustable window for fine-tuning the end position at commissioning, but it does not lock the load without continuous air pressure.
