About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30S
The AirTAC SAIJ100X90-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 60-90 mm usable travel window. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads with precision. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The integrated magnet supports position sensing via AirTAC CMSE reed or DMSE electronic switches. It shares the exact mounting footprint of standard ISO 15552 cylinders, allowing straightforward dimensionally interchangeable upgrades.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30S Is Used
Product Changeover
Quickly dial in the 60-90 mm travel window when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
Press Fit Tuning
Fine-tune the end-stop during commissioning to achieve precise pressing forces without adding external shims or physical stops.
Heavy Material Handling
Leverage the 3927 N push force to move heavy pallets or fixtures, using the adjustable stroke to accommodate varying load widths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-30S the Right Cylinder?
Choose this 100 mm bore when a 50 mm bore (providing 982 N push at 0.5 MPa) is insufficient, but a 125 mm bore is too large. The adjustable 30 mm stroke is ideal for dialing in exact end positions during machine setup or product changeover without swapping cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock. If your application requires load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. For exact ISO 15552 replacement matching, verify the 100 mm bore, 90 mm stroke, 30 mm adjustment, PT ports, and -S magnet requirement.
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 SAIJ100BX90-30S 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 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw allows you to shorten the 90 mm nominal stroke by up to 30 mm, creating a 60-90 mm usable travel window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
