About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-10S
The AirTAC SAIJ100X120-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 110 to 120 mm. It integrates a -S magnet for position sensing and features a SUS420J2 stainless steel rod with a PT tapered G1/2 port. Delivering 3927N of push force at 0.5 MPa, it handles heavy loads with precision.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-10S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within a 110-120mm window during machine commissioning without adding external stops.
Product Size Changeover
Quickly adapt the cylinder's effective stroke by up to 10mm on packaging lines handling varying product lengths.
Heavy Load Positioning
Leverage the 3927N push force at 0.5 MPa to move heavy pallets or fixtures while using the rear screw for final positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-10S the Right Cylinder?
Choose this 100mm bore when 80mm (2513N at 0.5 MPa) is insufficient for your heavy push loads, or step down if 63mm (1559N) is enough. The 10mm adjustment range is ideal for product changeovers requiring slight end-stop variations. For strokes of 300mm or more, add an external guide to prevent side-loading.
When ordering, specify the PT G1/2 port, SUS420J2 rod material, and the -S magnet option. The rear adjuster acts only as a travel stop and does not hold loads without live air; for true load-holding, select the SAIL lock or BSAI clamp-lock cylinder series.
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 SAIJ100AX120-10S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw lets you shorten the 120mm nominal stroke by up to 10mm, creating a 110-120mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
