About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-75
The AirTAC SAIJ100X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 90 mm stroke that can be dialed back by up to 75 mm, creating a highly flexible 15 to 90 mm usable travel window for precise end-position tuning during commissioning.
This model features an SUS420J2 stainless steel rod for enhanced durability against side loads and moisture. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It uses a G1/2 port and supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX90-75 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance from 15 to 90 mm on packaging equipment to accommodate different package sizes without changing the cylinder.
Machine Changeover
Rapidly adjust the stroke end-position during production line format changes, saving downtime compared to physically swapping out fixed-stroke actuators.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-75 the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial force 3927 N at 0.5 MPa but demands variable end-stops for frequent product changeovers. If your process needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The rear adjuster screw acts strictly as a travel stop to fine-tune the retract position without swapping cylinders; it does not hold the load without live air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI series cylinder.
To match this ISO 15552 interchangeable cylinder, verify the 100 mm bore, 90 mm nominal stroke, 75 mm adjustment range, PT tapered G1/2 port, and your required mounting set. Since the adjustment range is large relative to the stroke, ensure the physical stopper mechanism does not interfere with your tooling at the minimum 15 mm travel position.
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 SAIJ100AX90-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 75 mm. This means the 90 mm nominal stroke can be fine-tuned down to a minimum travel of 15 mm without adding external stops.
