About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-30S
The AirTAC SAIJ100X90-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 90 mm stroke that can be dialed back by up to 30 mm, giving you a precise 60-90 mm usable travel window for exact end-position tuning at commissioning. In the 100 mm bore class, it delivers substantial thrust, pushing 3927 N at 0.5 MPa and up to 7068 N at 0.9 MPa.
This unit includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses a G1/2 port and offers variable air cushions at both ends to decelerate moving loads smoothly.

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 SAIJ100AX90-30S Is Used
Product Changeovers
Dial in the 60-90 mm stroke window during packaging line format changes to accommodate different carton sizes without replacing the cylinder.
Machine Setup
Fine-tune the retract end-position during commissioning to perfect a pressing or clamping operation, avoiding the need for external mechanical stops.
Variable End Stops
Adjust the travel end on automated assembly equipment to test different material thicknesses or positions quickly and accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-30S the Right Cylinder?
The SAIJ100X90-30-S is selected over a fixed SAI model when you need a variable end-stop for product changeovers.
Because the stroke is 90 mm, external side-load guides are less critical than on longer strokes, but the 25 mm rod and M20x1.5 thread handle robust loads. The rear adjuster acts strictly as a travel stop, not a lock; it cannot hold a load without live air pressure. For load-holding without pressure, use an AirTAC SAIL or BSAI cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread.
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 SAIJ100AX90-30S FAQ
It features a rear adjusting screw that lets you shorten the effective stroke by up to 30 mm. With the 90 mm nominal stroke, this creates an adjustable travel window of 60-90 mm, allowing you to set the exact retract end-position without adding external stops.
At 0.9 MPa, the push force increases to 7068 N.
