About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-30
The AirTAC SAIJ100X260-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 230-260 mm usable travel window, allowing you to dial back the nominal 260 mm stroke by up to 30 mm during commissioning without adding external stops.
This unit is built with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

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 SAIJ100AX260-30 Is Used
End-Stop Tuning
Dial in the exact 230-260 mm retraction point during machine commissioning to perfect product seating without swapping hardware.
Changeover Adjustment
Quickly adapt the cylinder's travel window on packaging lines when switching between different product sizes or formats.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-30 the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N) is too weak but 125 mm (6136 N) is physically oversized. An adjustable stroke is selected over a fixed SAI when a machine requires fine end-position tuning or frequent product changeovers. The rear adjuster acts purely as a travel stop to decelerate the load; it does not hold position without live air. For load-holding without pressure, use an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
To match this ISO 15552 cylinder for a retrofit, specify a 100 mm bore, 260 mm stroke, 30 mm adjustment, PT port, and no magnet. Because the 260 mm stroke exceeds 300 mm only marginally, side loads are minimal, but for any unsupported overhung loads, an external guide is still recommended to prevent rod bending.
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 SAIJ100AX260-30 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a 230-260 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
