About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-75S
The AirTAC SAIJ80X900-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a usable 825-900 mm window. The extruded aluminum barrel includes sensor grooves on both sides, and this specific SKU is equipped with a magnet for position feedback.
This model uses a SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to dial in the exact end position during commissioning or product changeovers without swapping the cylinder. It is important to note that this adjuster is not a lock; it cannot hold a load without live air pressure, so for fail-safe load holding you should look to the SAIL or BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX900-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 825-900mm range during machine commissioning without adding external mechanical stops.
Product Size Changeover
Quickly adapt the stroke length on automated lines when processing different product sizes, using the rear screw to shift the travel endpoint.
Long-Travel Conveying
Drive long-stroke material handling gates or pushers where a standard 900mm stroke needs occasional fine-tuning to prevent overtravel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX900-75S the Right Cylinder?
Select this adjustable-stroke cylinder when an application requires precise end-position tuning over a long 900 mm travel. Because the stroke is 900mm, an external guide is highly recommended to prevent excessive side-loading on the rod.
Choose the SAIJ adjustable version over a fixed SAI cylinder when you need variable end-stops for machine setup or accommodating product size changes on a line. For an exact ISO 15552 replacement match, configure with an 80mm bore, 900mm stroke, 75mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a magnet (-S). The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80AX900-75S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 75mm, creating a usable travel window of 825 to 900mm. It is a travel stop, not a lock, and cannot hold a load without continuous air pressure.
