About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-100S
The AirTAC SAIJ100X375-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 275 to 375 mm, allowing you to dial back the nominal 375 mm stroke by up to 100 mm during machine commissioning or product changeover.
This specific SKU includes an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. It comes with a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic switches mounted in the dual-side sensor grooves. The extruded aluminum barrel design omits tie-rods, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX375-100S Is Used
Variable End-Stop Machining
Fine-tune the clamping travel window between 275 and 375 mm on the fly to accommodate different raw material thicknesses without changing out the cylinder.
Product Changeover Diverter
Adjust the rear stopper by up to 100 mm during line changeovers to precisely position diverter arms for varying package lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-100S the Right Cylinder?
The 100 mm adjustment range is ideal for applications needing significant end-position variance without swapping cylinders. Because the stroke is 375 mm, an external guide is recommended to prevent excessive side-load on the 25 mm rod. The rear adjuster acts purely as a travel stop for the air cushion and does not hold the load without live air; for true drop-prevention, use a SAIL or BSAI cylinder.
When matching an ISO 15552 replacement, verify the 375 mm stroke, 100 mm adjustment range, PT G1/2 port, and the -S magnet requirement. The rod thread is M20x1.5.
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 SAIJ100AX375-100S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to trim the effective travel back by up to 100 mm from the nominal 375 mm stroke, creating a usable window of 275 to 375 mm. It functions as an end-position stop for the cushion and does not lock the load without live air pressure.
