About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX270-75
The AirTAC SAIJ100X270-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 270 mm travel by up to 75 mm. This yields a usable end-position window of 195 to 270 mm, enabling fine-tuning at commissioning without swapping the cylinder or adding external stops.
This model features a PT tapered G1/2 port and variable air cushions at both ends to decelerate the load smoothly. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the -S magnet. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.

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 SAIJ100AX270-75 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 195 and 270 mm during machine setup to accommodate different material thicknesses without mechanical shims.
Product Size Changeovers
Quickly adjust the effective stroke on packaging lines when switching between product formats, minimizing downtime and avoiding cylinder swaps.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX270-75 the Right Cylinder?
Choose this SAIJ100X270-75 when your application requires heavy thrust and precise, variable end-stops. The 75 mm adjustment range is ideal for product-size changeovers on a line, letting you reposition the stopper rather than replacing the entire cylinder. Because the total stroke is 270 mm, ensure you use an external guide to support the rod and prevent excessive side-load wear.
When matching this for an ISO 15552 replacement, verify the 100 mm bore, 270 mm stroke, 75 mm adjustment, PT G1/2 port, and your required mounting style. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. If you need position feedback, select an equivalent SKU with the -S option to use AirTAC CMSE reed or DMSE electronic sensors.

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 SAIJ100AX270-75 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the nominal 270 mm stroke by up to 75 mm, providing an effective travel window of 195 to 270 mm. It only sets the end position and does not lock the load without live air pressure.
