About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-20
By turning the external stopper screw, you achieve a usable travel window of 85 to 105 mm, allowing precise end-position calibration without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.
This model features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and pairs with a G1/2 port. The rear adjuster acts strictly as a travel stop to set deceleration limits; it does not hold the load without live air pressure. For position-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ100AX105-20 Is Used
Machine Setup & Changeover
Dial in the exact 85 to 105 mm retract position during product size changes without replacing the cylinder or adding machined spacers.
End-Stop Calibration
Use the rear adjustment screw to fine-tune the final end-position during commissioning, ensuring precise placement of heavy 100 mm bore tooling.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-20 the Right Cylinder?
The adjustable 85-105 mm travel is ideal for product changeovers on a line, letting you fine-tune the retract distance at commissioning rather than machining external stops. To match this ISO 15552 replacement, verify the 105 mm stroke, 20 mm adjustment, PT tapered port, and your required mounting bracket from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 105 mm stroke is relatively short, side-loading is minimal, but always guide external loads to protect the rod seals.
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 SAIJ100AX105-20 FAQ
The rear adjuster screw lets you trim the effective stroke within an 85 to 105 mm window. It functions as a travel stop to set deceleration and end-positions, but it does not lock or hold the load without continuous air pressure.
