About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-100
The AirTAC SAIJ100X475-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 375 to 475 mm. Delivering 3927 N of push force at 0.5 MPa, it handles heavy-duty positioning tasks. The standard extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant is equipped with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The 100 mm adjustment range allows you to fine-tune the retract end position at commissioning without adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-100 Is Used
Variable End-Stop Tuning
Dial in the retract position precisely during machine commissioning using the 100 mm adjustment screw, avoiding the need to swap cylinders for minor position changes.
Product Size Changeover
Adapt automated lines to different product lengths quickly by shifting the effective stroke within the 375-475 mm window.
Heavy-Duty Positioning
Leverage 3927 N of push force at 0.5 MPa to move heavy pallets or fixtures while relying on the SUS304 rod for corrosion resistance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-100 the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder (providing 2513 N push at 0.5 MPa) is insufficient for your load. The generous 100 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, serving as a variable end-stop rather than requiring a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, pair this cylinder with an external rod lock or select the BSAI clamp-lock series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 475 mm stroke, 100 mm adjustment, G1/2 port, and mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 475 mm, an external guide is recommended to prevent excessive side-loading on the 25 mm rod.
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 SAIJ100BX475-100 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 7068 N push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel anywhere between 375 and 475 mm. It decelerates the travel end but does not lock the load without live air pressure.
