About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-20S
The AirTAC SAIJ100X800-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel by up to 20 mm, creating a 780-800 mm usable stroke window for precise end-position tuning. This variant includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet for position sensing.
The rear adjuster functions strictly as a travel stop to fine-tune deceleration and end points during commissioning; it does not hold the load without live air pressure. For load-holding without continuous pneumatic supply, an external rod lock or related types like SAIL or BSAI should be used. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches.

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 SAIJ100AX800-20S Is Used
Machine Changeover
Dial in the 780-800 mm end-stop during product size transitions without physically swapping the cylinder or bolting on external stops.
Large Assembly Presses
Apply the 800 mm stroke for long-travel assembly operations, adjusting the travel end by up to 20 mm to accommodate varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-20S the Right Cylinder?
Choose this 100 mm bore when your application requires high thrust, such as shifting heavy fixtures, and you need to dial in the exact end-stop without adding external bumpers. The adjustable stroke is ideal for product changeovers on a line where the end position varies slightly by part size, replacing the need to physically swap a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 800 mm stroke, 20 mm adjustment range, PT tapered port thread, and the -S magnet requirement. Because the stroke is 800 mm, the long unsupported piston rod is susceptible to side-loading; an external guide should be used to prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ100AX800-20S FAQ
The maximum operating pressure is 1.0 MPa.
The rear adjuster acts as a stopper that can trim the nominal 800 mm stroke back by up to 20 mm, providing a usable travel window of 780-800 mm. It only sets the end position and does not lock the load without live air pressure.
