About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-10
The AirTAC SAIJ100X90-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 80-90 mm usable travel window from its 90 mm nominal stroke. It delivers 3927 N of push force at 0.5 MPa, making it robust enough for heavy handling tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and carries a PT tapered port thread. The rear adjustment screw acts as a travel stop to fine-tune end positions at commissioning, but it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-10 Is Used
Machine Setup Tuning
Fine-tune the 80-90 mm travel window during initial commissioning to dial in exact end positions for precision presses without external stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm on packaging lines when handling slightly different box sizes, minimizing downtime.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or chassis components reliably through the adjustable travel path.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-10 the Right Cylinder?
Select this 100 mm bore cylinder when a 63 mm bore (providing 1559 N push at 0.5 MPa) is insufficient, but you want to avoid stepping up to a massive 125 mm body. The adjustable stroke is ideal for product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops. For true load-holding without live air, consider the SAIL or BSAI series instead of relying on this adjuster.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 10 mm adjustment range, G1/2 port, and mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Since no -S magnet is specified, this unit will not work with CMSE or DMSE sensors without a magnet upgrade.
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 SAIJ100BX90-10 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 90 mm nominal stroke by up to 10 mm, creating an 80-90 mm usable travel window. It functions as an end-stop for position tuning, not a lock, and requires live air to hold the load.
