About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40S
The AirTAC SAIJ100X90-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 90 mm travel that can be fine-tuned down by up to 40 mm, creating a precise 50-90 mm usable window. Delivering 5497 N of push force at 0.7 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
The integrated rear stopper allows you to dial in the exact retract end-position during commissioning without adding external stops. The adjuster acts solely as a travel limit and deceleration point, not a lock, meaning it cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 50 and 90 mm during machine setup to accommodate changing material thicknesses without replacing hardware.
Product Changeover Systems
Rapidly adjust the stroke window on packaging or assembly lines when switching to a new product size, minimizing downtime.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable high-force pushing in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-40S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, stepping up from the 63 mm bore that yields 2182 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers on a line, letting you set variable end-stops on the fly rather than swapping out a fixed-stroke SAI cylinder. The 25 mm rod and M20x1.5 thread handle high side loads, though any stroke over 300 mm would require an external guide.
To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 90 mm stroke, 40 mm adjustment, PT tapered port threads, and the -S magnet option compatible with CMSE reed and DMSE electronic sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ100BX90-40S FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At 0.5 MPa, it yields 3927 N push and 3681 N pull.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 40 mm, providing a usable travel window of 50 to 90 mm. This stopper only sets the end position; it does not lock the load without live air pressure.
