About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-75S
The AirTAC SAIJ100X900-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 825 to 900 mm.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses a PT tapered G1/2 port. It carries an integrated magnet for CMSE reed and DMSE electronic sensors. The rear adjuster acts strictly as a travel stop for deceleration, not a load-holding lock, so live air pressure is required to maintain position.

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 SAIJ100AX900-75S Is Used
Long-Stroke Machining
Dial in the 825-900mm travel window to fine-tune clamping positions on large machining centers without repositioning the cylinder.
Product Changeover
Adjust the retract stop by up to 75mm on packaging lines to handle varying box sizes quickly during product transitions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-75S the Right Cylinder?
The 75mm adjustment range is ideal for product changeovers on long-stroke machinery, letting you dial in the exact end-stop without swapping the cylinder. For fixed-position tasks without live air, select a SAIL lock or BSAI clamp-lock cylinder instead of relying on this adjuster.
At 900mm stroke, the M20x1.5 rod is highly susceptible to side-loading and bending; always use an external guide to support the load. To match this ISO 15552 replacement, specify the 100mm bore, 900mm stroke, 75mm adjustment, PT G1/2 port, and the -S magnet. SAIJ mounting options are Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX900-75S FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw lets you mechanically shorten the 900mm nominal stroke by up to 75mm, providing an effective travel range of 825 to 900mm. It functions as a travel stop to set deceleration and end positions, not as a lock to hold the load without air pressure.
