About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-100
The AirTAC SAIJ40X105-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from the 105mm nominal stroke to a highly flexible 5-105mm window. It delivers 628N of push force and 528N of pull force at 0.5MPa, making it well-suited for medium-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
This specific SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw functions strictly as a mechanical stop to dial in the end position during commissioning or product changeovers without adding external stops. It is not a locking device and will not hold a load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-100 Is Used
Product Changeover
Dial in the 5-105mm travel window during machine format changes to handle varying package sizes without swapping hardware.
End-Position Tuning
Fine-tune the exact retract distance during initial commissioning using the rear stopper rather than relying on fixed mechanical spacers.
Assembly Station Setup
Establish precise clamping or pressing endpoints on the fly for medium-force 628N assembly operations.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-100 the Right Cylinder?
Choose this 40mm bore adjustable-stroke cylinder when your application requires frequent end-position adjustments or variable product sizes on a single line, stepping up from a 32mm bore that provides 402N push force at 0.5MPa. The 16mm piston rod and M12x1.25 thread provide a robust interface that handles moderate side loads well, though any long unsupported travel still requires an external guide. If your process demands true load-holding without continuous air pressure, consider the SAIL or BSAI series instead. This SAIJ model supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ40 Adjustable Cylinder SAIJ40BX105-100 FAQ
It provides 628N push and 528N pull force at 0.5MPa, reaching 879N push at 0.7MPa. The operational speed range is 30-800mm/s.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 105mm nominal stroke anywhere down to 5mm, creating a 5-105mm usable travel window without replacing the cylinder.
