About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-40S
The AirTAC SAIJ100X350-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 350 mm nominal stroke by up to 40 mm. This yields a precise 310-350 mm usable travel window, allowing exact end-position tuning at commissioning without swapping hardware.
Because it includes a magnet (-S), this model directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves. The rear adjuster acts purely as a mechanical stop to set the travel limit and relies on the integrated air cushions for end-of-stroke deceleration; it is not a locking mechanism and will not hold a 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 SAIJ100AX350-40S Is Used
Product Changeover Dials
Quickly shift the end-stop by up to 40 mm during packaging line format changes without disassembling the actuator assembly.
Commissioning Fine-Tune
Trim the 350 mm stroke down to a 310 mm minimum to perfectly seat components or time press strokes during initial machine setup.
Variable End Stops
Set precise retract positions for multi-tier assembly processes, using the rear stop screw to adapt travel limits on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-40S the Right Cylinder?
The 40 mm adjustment window is perfect for product changeovers or varying end-stops on the fly, replacing the need for fixed-stroke SAI cylinders and external spacers. To match this ISO 15552 footprint exactly, specify bore 100, 350 mm stroke, PT ports, SUS420J2 rod material, and the -S magnet.
At 350 mm, the stroke is substantial, so an external guide is highly recommended to prevent side-loading damage to the M20x1.5 rod thread and cylinder seals. If your application requires true load holding without continuous air pressure, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead, as the SAIJ adjuster only restricts travel. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX350-40S FAQ
At the maximum 1.0 MPa pressure, it can output up to 801 kgf.
The rear adjuster lets you shorten the 350 mm nominal stroke by up to 40 mm, creating a 310-350 mm usable travel window. This mechanical stop fine-tunes the end position at commissioning but does not lock or hold the load without live air pressure.
