About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-100
The AirTAC SAIJ100X300-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. With a nominal stroke of 300mm and a 100mm adjustment range, you can dial back the effective travel to anywhere within a 200-300mm window without swapping hardware.
This unit features a SUS420J2 stainless steel rod for enhanced durability against moisture and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic switches directly. Because the 300mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the rod.

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 SAIJ100AX300-100 Is Used
Variable End-Stop Configuration
Ideal for assembly lines processing multiple part sizes, allowing operators to dial the stroke back from 300mm down to 200mm directly at the rear screw during changeover.
Long-Stroke Material Handling
Handles robust 300mm travel transitions in automated machinery, where the fine-tuning capability prevents hard crashes during initial machine setup.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-100 the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your application requires heavy pushing power but exact end-positioning varies by product type. If 5497N at 0.7 MPa is excessive, stepping down to an 80mm bore yields 3518N; if you need more force, a 125mm bore provides 8590N. The 100mm adjustment screw allows massive flexibility during machine setup or product changeover, eliminating the need to bolt on external stops or buy multiple fixed-stroke SAI cylinders.
For an exact ISO 15552 replacement match, ensure your specifications align with this 100mm bore, 300mm stroke, 100mm adjuster, PT port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-air load holding, consider an SAIL or BSAI variant.
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 SAIJ100AX300-100 FAQ
At 0.7 MPa, the push force increases to 5497N, and it reaches a maximum of 801 kgf at 1.0 MPa.
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the 300mm nominal stroke down to a minimum of 200mm. It only sets the end position and does not lock the load without continuous air pressure.
