About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-20
The AirTAC SAIJ100X75-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 75mm travel that can be fine-tuned down by up to 20mm, yielding a precise 55-75mm usable stroke window for exact end-position calibration at commissioning.
This unit is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to set the retract end, meaning 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 SAIJ100AX75-20 Is Used
Machining Changeover
Dial in the 55-75mm stroke window during product changeovers to set exact clamping depths without reinstalling fixed stops.
Component Insertion
Fine-tune the insertion end-position of electronic connectors, ensuring precise seating depth that varies by part number.
Conveyor Diverter Setup
Adjust the retract distance of a diverter arm on the fly to accommodate different package sizes moving down the line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-20 the Right Cylinder?
Select this 100mm bore adjustable-stroke cylinder when your application requires precise positioning within a 55-75mm travel window. If your setup demands less force, stepping down to an 80mm bore yields 2513N at 0.5MPa, avoiding excessive bulk. Conversely, moving up to a 125mm bore provides 6136N for heavier payloads. The integrated rear screw allows you to dial in the exact end-stop during machine changeover without swapping out the entire cylinder or adding external stops.
For ISO 15552 dimensional interchangeability, match the 100mm bore, 75mm nominal stroke, PT port threads, and the 20mm adjustment range. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the rear adjuster is a stop and not a lock, utilize a SAIL or BSAI cylinder if your application requires true load-holding without continuous air pressure.
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 SAIJ100AX75-20 FAQ
The rear adjuster screw lets you shorten the 75mm nominal stroke by up to 20mm, creating a 55-75mm usable travel window. It functions as a mechanical stop to set the end position and is not a lock, meaning it cannot hold the load without live air pressure.
