About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-100
The AirTAC SAIJ100X375-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. With a 375 mm nominal stroke and a 100 mm adjustment code, it provides a usable travel window of 275-375 mm. This wide adjustment range is ideal for product changeovers on a line, letting you reset the retract end-stop without swapping the cylinder or adding external stops. It delivers a robust 3927 N push force at 0.5 MPa.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a mechanical stop to set the travel end; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-100 Is Used
Product Changeover
Dial in the retract position by up to 100 mm when switching product sizes on a packaging line, eliminating the need to physically swap cylinders.
End-Position Tuning
Fine-tune the travel end at commissioning to hit exact mechanical stops without machining new mounting plates or adding external spacers.
Heavy Forming Operations
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks where the exact bottoming position must be dialed in on-site.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-100 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires heavy thrust (3927 N push at 0.5 MPa) and frequent end-position tuning. If you need less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa. If you require more power, a 125 mm bore provides 6136 N push. The adjustable stroke is perfect for machine setup and commissioning, offering a variable end-stop that a fixed-stroke SAI cylinder cannot match. To replace this unit, match the 100 mm bore, 375 mm stroke, 100 mm adjustment, PT port, and mounting style. Because the stroke is 375 mm, ensure you use an external guide to support the load and prevent excessive side-loading on the 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 SAIJ100BX375-100 FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 100 mm. This gives you a usable travel window of 275-375 mm, allowing you to set the exact retract end position during commissioning without replacing the cylinder.
At a 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
