About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-20S
The AirTAC SAIJ100X65-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops when dialing in end positions.
This SKU is configured with an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides, and fluid is supplied via PT tapered G1/2 ports. The rear adjuster acts strictly as a travel stop, meaning it does not hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX65-20S Is Used
Machine Setup Changeover
Fine-tune the 45-65mm travel window during product line changeovers to accommodate different part sizes without physically swapping the actuator.
Variable End-Stop Tuning
Dial in the exact retract position at commissioning using the rear screw, avoiding the need to add external mechanical stops to the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX65-20S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers without replacing the actuator. For load-holding without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI series instead.
To replace an ISO 15552 cylinder, match the 100mm bore, 65mm stroke, 20mm adjustment, PT G1/2 port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 25mm rod and M20x1.5 thread handle high side loads, this cylinder manages stress well, though any long unsupported stroke still requires an external guide.
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 SAIJ100AX65-20S FAQ
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 65mm nominal stroke by up to 20mm, providing a usable travel range of 45-65mm. This stopper only sets the end position and does not lock the load without live air.
