About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-75
The AirTAC SAIJ100X260-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 185 to 260 mm, allowing you to trim the nominal 260 mm stroke by up to 75 mm during commissioning.
This model uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops.

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 SAIJ100AX260-75 Is Used
Product Changeover Tooling
Dial in the 185-260 mm travel window during line changeovers to accommodate different product lengths without swapping out the entire cylinder assembly.
Conveyor Diverting
Fine-tune the retract stroke on sorting gates to handle varying package sizes precisely, using the rear stopper to set the exact resting position.
Assembly Press End-Stop
Set the exact end-of-stroke position for pressing operations, allowing 75 mm of flexibility to adjust the press depth without repositioning the cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-75 the Right Cylinder?
If your force requirements are lower, stepping down to an 80 mm bore provides 2513 N at 0.5 MPa. The 75 mm adjustment range is ideal for product changeovers where multiple end-stops are needed on a single fixture.
For ISO 15552 replacement, match the 100 mm bore, 260 mm stroke, G1/2 PT port, and the desired mounting style from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that this cylinder does not hold its load without live air pressure; the rear adjuster is a travel stop, not a lock. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. Because the 260 mm stroke is substantial, use an external guide to prevent side-load damage.
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 SAIJ100AX260-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 260 mm down to as little as 185 mm. It allows fine-tuning the end position at commissioning without changing the cylinder, but it does not lock the load without live air pressure.
