About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-75S
The AirTAC SAIJ100X225-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 150-225 mm window. Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore actuator handles substantial loads. It is equipped with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
Because the adjuster acts purely as a mechanical stop, it relies on the integrated air cushions for end-of-stroke deceleration and cannot hold a load without continuous air pressure. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches for precise feedback. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-75S Is Used
Product Changeovers
Dial in the 150-225 mm travel window during format changeovers to accommodate varying package sizes without changing cylinders.
Machine Setup
Fine-tune the exact end-of-stroke position at commissioning to achieve precise mechanical alignment without adding external stoppers.
Variable End Stops
Use the 75 mm adjustment range to modify the retract position dynamically for flexible manufacturing lines and varied process depths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-75S the Right Cylinder?
Choose this 100 mm bore if your application requires the 3927 N push force at 0.5 MPa; stepping down to an 80 mm bore drops the push force to 2513 N, while moving up to 125 mm increases it to 6136 N. The 75 mm adjustment range is ideal for machinery that frequently processes different product sizes, allowing you to shift the end-stop during changeovers without physically swapping the cylinder. The PT tapered ports and -S magnet configuration ensure leak-free pneumatics and reliable sensor feedback.
Since the nominal stroke is 225 mm, an external guide should be considered to manage side loads and prevent rod binding. Remember that the rear adjuster is a travel stop, not a locking device; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting set that omits FB, CA, CB, and CR brackets.
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 SAIJ100BX225-75S FAQ
At 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 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 225 mm down to 150 mm. It sets the travel end but does not lock the load without live air pressure.
