About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-20
The AirTAC SAIJ100X700-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 680 to 700 mm window. The barrel is extruded aluminum with sensor grooves on both sides for flexible switch placement.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered port threads. The rear adjuster acts purely as a travel stop to dial in the end position during commissioning; it does not lock or hold the load without live air pressure. For applications requiring position holding, a SAIL or BSAI series cylinder is recommended.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-20 Is Used
Machine Setup Calibration
Dial in the exact 680 to 700 mm end position during initial commissioning without machining external stop blocks.
Product Changeover
Quickly trim the stroke by up to 20 mm on the rear screw when switching production lines to accommodate a slightly shorter workpiece.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX700-20 the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires substantial thrust—stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while moving up to 125 mm yields 6136 N. The adjustable stroke is highly beneficial for machine setup and product changeover, allowing you to trim up to 20 mm of travel without swapping the cylinder or adding external stops. Because the nominal stroke is 700 mm, an external guide is strongly recommended to prevent excessive side-loading on the rod.
When specifying a replacement, ensure you match the 100 mm bore, 700 mm stroke, 20 mm adjustment, PT G1/2 port, and the SUS420J2 rod material. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If you need position feedback, adding an -S magnet allows the use of AirTAC CMSE reed or DMSE electronic sensors.

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 SAIJ100AX700-20 FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 700 mm nominal stroke by up to 20 mm, resulting in a 680 to 700 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
