About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-75
The AirTAC SAIJ100X900-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 900mm nominal stroke that can be dialed back by up to 75mm, creating an exact 825-900mm usable travel window for precise end-position tuning.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The rear adjuster acts purely as a mechanical stop to set the travel end and deceleration point, so it does not hold the load without live air pressure.

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 SAIJ100AX900-75 Is Used
Variable End-Stop Machining
Dial in the 825-900mm travel window to set precise feed positions for machining different part lengths without external physical stops.
Product Changeover Diverter
Quickly adjust the retract end position on a conveyor sorting line to handle varying package sizes during production run transitions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-75 the Right Cylinder?
Select this 100mm bore cylinder when an application requires substantial thrust—stepping down to an 80mm bore yields 3518N at 0.7MPa, while this 100mm bore provides 5497N. The adjustable 825-900mm stroke is ideal for machine setups requiring variable end-stops or product changeovers without swapping out the entire actuator. To replace an ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 75mm adjustment, PT ports, and the SUS420J2 rod material.
Because the 900mm stroke is quite long, an external guide is strongly recommended to prevent rod sag and manage side loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If the machine requires true load-holding without continuous air pressure, use an SAIL lock or BSAI clamp-lock cylinder instead of relying on the rear stopper.
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 SAIJ100AX900-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 900mm down to 825mm. It sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
