About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-75
The AirTAC SAIJ100X750-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 750 mm stroke that can be fine-tuned backward by up to 75 mm, creating a usable travel window of 675 to 750 mm. Delivering 3927 N of push force at 0.5 MPa, it is built for heavy-duty positioning tasks.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and includes dual-side sensor grooves for flexible mounting. The rear adjuster acts purely as a travel stop for end-position tuning during commissioning; it does not lock the load without live air pressure. For load-holding requirements, consider the SAIL or BSAJ series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-75 Is Used
Variable End-Stop Positioning
Dial in the 675-750 mm travel window during machine setup to accommodate varying product lengths without physically replacing the actuator.
Heavy-Duty Changeover
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets, using the rear screw to quickly reset the end position for new production runs.
Long-Stroke Forming
Utilize the 750 mm travel for extended pressing or forming actions, relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-75 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, which may be insufficient for heavy loads. The 75 mm adjustment range is ideal for machinery changeovers where the exact end-of-stroke position varies by product size, eliminating the need to swap cylinders or add external stops. Because the stroke is 750 mm, an external guide is recommended to prevent excessive side-loading on the long, unsupported rod.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 750 mm stroke, 75 mm adjustment, PT tapered port threads, and the SUS304 (B) rod material. The mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this model lacks a magnet; use external sensors if detection is required.
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 SAIJ100BX750-75 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. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjusting screw allows you to shorten the effective stroke by up to 75 mm from the nominal 750 mm, providing a usable travel range of 675 to 750 mm. This stopper only sets the end position and does not hold the load without continuous air pressure.
